Re: how to get help if no answer from this list?
Dr. Exner, It helps to understand classloading in Tomcat. I just got Axis up and running on the following system. Windows/2000 Professional Java JDK 1.5.0_04 Tomcat 5.59 I will assume that this works the same on my Linux box (Fedora Core 4) since Apache is great in making cross-platform tools. The reference in the Tomcat documentation you want is the following: http://localhost:8080/tomcat-docs/class-loader-howto.html In particular, the following paragraph: For classes and resources that must be shared across all web applications, place unpacked classes and resources under $CATALINA_BASE/shared/classes, or place JAR files containing those classes and resources under $CATALINA_BASE/shared/lib. For my environment, this is what I did. 1) Downloaded axis-bin-1_3.zip 2) Unzipped it someplace convenient (C:\src\axis-1_3) 3) Copied the axis folder under webapps to my $CATALINA_HOME\webapps 4) Ran the Axis Happiness Page and noted I needed the following jars a) activation.jar b) mailapi.jar c) xmlsec.jar 5) Read the instructions and picked up the jars from the appropriate places. The first two are from Sun, and the last one is from Apache. 6) Dropped the jars in $CATALINA_HOME\shared\lib since I expect to write multiple webapps with Axis 7) Stopped and restated Tomcat The Axis Happiness Page now reports happiness. In general, if you need jars in a single web application, put them in WEB-INF\lib of the webapp. If you need to share libraries across all web applications, put the jar in $CATALINA_HOME\shared\lib. If you need to have Tomcat use them as well (for example, JDBC drivers to set up JNDI datasources), then you put the jars in $CATALINA_HOME\common\lib (see http://localhost:8080/tomcat-docs/jndi-datasource-examples-howto.html) Hope this helps. /mde/ --- Dr. Exner [EMAIL PROTECTED] wrote: Thanks for this hint, but it did not work.

You might try using existing environment variables. %HOMEPATH% is the user's home path, but they might not like having temporary files stuffed into their Documents and Settings directory. Maybe %HOMEPATH%\My Documents wouldn't be too bad. Or, you could use the TMP or TEMP environment variable. Just type: set at a command prompt to see what environment variables are available to use. Finally, if you do use one of those environment variables, it might be nice to rewrite the batch file so that it creates a subdirectory if one doesn't exist. Cleaning up when you shut down would also be nice.

There are lots of reasons to run Apache in front of Tomcat, and lots of reasons not to. This just depends on your use cases and web site. At any rate, here's one way to find out in your case if the Apache -- ajp13 -- Tomcat process is your bottleneck. 1. Get jmeter at http://jakarta.apache.org/jmeter/ 2. Design and run tests against your web site as: http://yourhost/yoursite/ 3. Design and run test against your web site as: http://yourhost:8080/yoursite/ Caveats 1. Your static content will have to be available to Tomcat 2. Tomcat will have to run the http connector on 8080 (or another port - check server.xml) 3. You will have to be able to connect to your web site on the port listed in caveat 2. just some random thoughts . . . . /mde/ __ Do You Yahoo!? Tired of spam? Yahoo!

Re: Site Configuration on 5.5.15 Pt 2
There are probably a couple of things going on here. On the Aliasname/Alias, do you really need Tomcat to respond to the host name of www? You probably just want Tomcat to respond to www.theuniquepear.com and theuniquepear.com. I don't think the Aliaswww/Alias is necessary. It looks like www.theuniquepear.com is a CNAME for theuniquepear.com. A CNAME is resolved to the underlying name, so I think the resolution goes like this: a) www.theuniquepear.com is a CNAME for theuniquepear.come b) theuniquepear.com is used to get the address Google comes back with theuniquepear.com in its search results. Instead of a CNAME, you could use a separate A record to resolve www.theuniquepear.com to your web site. That still would leave you with a certificate problem if someone entered theuniquepear.com in the browser address bar. Maybe reversing the CNAME entries is what you need. In other words: www.theuniquepear.com IN A 66.128.124.198 theuniquepear.com IN CNAME www.theuniquepear.com That would get Google to return www.theuniquepear.com in irs search results. There would still be a certificate issue if someone typed theuniquepear.com in the browser address bar. Some thoughts on a solution: a) Not respond to theuniquepear.com as a web site. b) Virtual host that responds to theuniquepear.com consisting of a single page with a redirect to www.theuniquepear.com.

RE: Virtual Hosts [mostly solved]
You may find that the default host loads all of the web applications. In order to solve this, make sure that each of the contexts are not some subdirectory of another context. Host name=localhost appBase=vhosts/local / Host name=foo.mydomain.com appBase=vhosts/foo / Host name=bar.mydomain.com appBase=vhosts/bar / Host name=eggs.mydomain.com appBase=vhosts/eggs / You can use an absolute path to place this structure outside of your Tomcat installation. For large structures I think this is nice, because then you can upgrade Tomcat without disturbing your applications. Cutover would involve installing a parallel Tomcat, modifying server.xml. shutting down the old version, and starting up the new version. If the new version failed, recovery is just shutting down the new version and starting up the old version. If you want a one-stop place for all of your web applications, please ignore this comment. For a root context, I usually set up an application.xml file in conf/Catalina/hostname/ with the appropriate path= in the Context element, or a context.xml file in the web application's META-INF directory with the same context information. Once you separate each of the virtual hosts so that subdirectories don't overlap, I think you will find that multiple manager applications work. The manager application will then be specific to the virtual host, and you'll have to access that manager application by going to the specific virtual host (ie, http://hostname:8080/manager/html) HTH /mde/ . . . . . just my two cents --- Gormley, Josh [EMAIL PROTECTED] wrote: With the help of several people on this list, I've been able to get my server configured [mostly] the way I wanted it configured.

Re: tomcat install/testing help.
Tom, I tried responding to you off-line, but alaska.gov does not seem to like your mail address. Basically, it sounds like you have a permissions problem with the account under which Tomcat runs. By default, the Tomcat service runs as the Local System account, so that account needs appropriate access to %CATALINA_HOME% (where Tomcat is installed), and its subdirectories. I hope that helps. /mde/ --- On Fri, 7/17/09, Burton, Tom (DOR sponsored) tom.bur...@alaska.gov wrote: From: Burton, Tom (DOR sponsored) tom.bur...@alaska.gov Subject: tomcat install/testing help.

Re: Trouble setting up virtual host
As usual, late to the thread. I'll use C) then: C) on another workstation : - close the browser and re-open it. - in the browser, find the place where you can clear the cache. - do it (clear the cache) - request the URL : http://adm138/InfoViewApp - indicate the result here : A: Internet Explorer cannot display the webpage This usually means that the other workstation cannot translate between the name you gave the host on the other workstation (adm138) and the IP address of your server. I also noticed that while you use the fully qualified name in the other example (www.fmdreports.vcu.edu) you use the short name in your tests (adm138). There are several things to try here, to see where the breakdown is. I'll use numbers since everyone else is using letters. 1. From another workstation, open a DOS window (if it's Windows) or a UNIX shell command (if it's UNIX), and type the following: ping adm138 1a) If you get: Ping could not find the host adm138, then the other workstation does not know how to translate between the name and the IP address. 1b) If you get: Four lines with a bunch of numbers, then the other workstation knows how to translate between the name and the IP address 2. From another workstation, open a DOS window (if it's Windows) or a UNIX shell command (if it's UNIX) and type the following: ping adm138.fmdreports.vcu.edu 2a) If you get: Ping could not find the host adm138.fmdreports.vcu.edu, then the other workstation does not know how to translate between the name and the IP address. 2b) If you get: Four lines with a bunch of numbers, then the other workstation knows how to translate between the name and the IP address adm138.fmdreports.vcu.edu may be the fully qualified name, but this depends on how your network administrator has set up something called DNS. Firewall check == Windows comes with a built-in firewall. On XP/Professional it's located in Start-Control Panel-Network Connections. You'll have to single-click on the active network (the one your server connects to) to see Change Firewall Settings on the left hand side. Once you click on that (Change Firewall Settings), you should be able to edit the settings by selecting Exceptions tab. Hopefully you'll see two entries for Java(TM) Platform SE Binary. Make sure that the JRE you're using to run Tomcat is there (by clicking on edit and reading the properties). Short term fix (once you've checked your firewall) == If you have administrative privileges on the other workstation (Windows) or root access (UNIX), you can add some information in a file called hosts. On Windows, it's located in the %windir%\System 32\drivers\etc directory. In UNIX it's located in /etc The line you need to add is the following: aaa.bbb.ccc.ddd adm138 where aaa.bbb.ccc.ddd is the IP address of the machine with your Tomcat server. If the fully qualified name is supposed to be adm138.fmdreports.vcu.edu, then add this line instead to the hosts file aaa.bbb.ccc.ddd adm138 adm138.fmdreports.vcu.edu where aaa.bbb.ccc.ddd is the IP address of the machine with your Tomcat server. Long term (proper) fixes = There are really two parts to this fix. The first part is to get your network administrator to add this hostname and IP address to your campus DNS server. The DNS server is responsible for translating between human-readable names and IP addresses. Once the name you have chosen for your server is in DNS, all machines using DNS servers will know how to interpret the name of the host. The second part of the fix is to alter your virtual host definition in server.xml. In general, it's a good idea to only use fully qualified names in the server.xml file. So, in part, your host element should look like this: Host name=fully-qualified-host-name . . . . /Host For example: Host name=adm138.fmdreports.vcu.edu . . . /Host However, if you want to have this virtual host respond to other names, you can add aliases for each name. To do that, just add an alias element for each name you want. Host name=fully-qualified-host-name . . . . Aliassome-other-name/Alias Aliasstill-another-name/Alias /Host For example: Host name=production.fmdreports.vcu.edu . . . Aliasadm138.fmdreports.vcu.edu/Alias Aliasanother.fmdreports.vcu.edu/Alias /Host If you want those aliases to be visible to other select workstations, then you will have to edit the hosts file for each workstation like I've shown above. Obviously, this is not a permanent fix if you have to edit 1000s of hosts on campus. If you want to have those alias names reachable from workstations that are not your server, then tell your network administrator what those names should be. Please remember if these names are going to be globally visible, you will have to use fully qualified names, not
RE: Someone Please: Why Is Tomcat Looking In The Wrong Directory?
As an additional comment: Based on earlier comments, it looks like the vendor's application is using the system property tomcat.home to create the file path to open. As you found out this will prevent using CATALINA_BASE or creating virtual hosts under one Tomcat. The vendor might look at using something like: getServletConfig().getServletContext().getRealPath(virtual) and then getting virtual fed in via a context-param in the web.xml file. That should return the real path to the file. It will fail when the application is being served from a .war file, but requiring the war file to be exploded should be OK. Just some random thoughts at the end of the thread. /mde/ --- Robinson, Eric [EMAIL PROTECTED] wrote: Okay, so I finally connected with someone at the vendor. Surprise!

Re: tomcat JSP Servlet Apache JK2
There are a lot of issues here, mostly having to do with how you've structured your virtual hosts. However, I think the following should get you up and running quickly. In your VirtualHost directive, add the following line: DirectoryIndex index.html index.html.var login.jsp That should bring up the login.jsp as a default index when someone just goes to the directory. Note, I have not tried this, but I do use this to serve up .pl and .php index files. I normally don't have a login.jsp page as the entry point into my web application. I normally put an index.html splash page with a note about the web application, and then on that page provide a link to the login page should the user want to log in. As I said above, there are a lot of potential issues with the way you've constructed virtual hosts, both with Apache and Tomcat. The Tomcat issues are certainly on topic for this mailing list, but the Apache issues are probably not.

Re: Measuring traffic pr. virtualhost
If you want to do logging on at the Engine, Host, or Context level, then you can use the access logging valve in Tomcat. Configuration information can be found here: http://tomcat.apache.org/tomcat-5.5-doc/config/valve.html Note that if you serve static material with a front-end Apache server, that will NOT be logged by the access logging valve (obviously). If you use mod_jk in Apache 2.0 (or I assume mod_proxy_ajp in Apache 2.2), then the web server can log everything. Just set up a log file per each VirtualHost. There is a lot of documentation in the httpd.conf file and in the Apache manual for setting up logging on Apache. The Tomcat logs are in the Apache common format (by default). There are many web statistics packages that will parse and analyze these files. If you want more detailed help, I would be happy to correspond with you off the mailing list, since log configurations for the Apache web server are probably not on topic here. /mde/ Just my two cents . . . . --- Lars Nielsen Lind [EMAIL PROTECTED] wrote: Hi.

This should be like any other web application. I just set it up as a test on my machine and it works fine.

This basically sends everything from: www.mydomain.com/mmbase/* to Tomcat. There are other ways of doing this, but this is sort of the minimalist approach.

Re: Tomcat dies suddenly
Carl, A couple of random thoughts . . . I'm not familiar with the Slackware monitoring tools, but I am with the various tools that come with Fedora / Redhat. One of the things that I've noticed with those GUI tools is that they add cache and buffers to the free memory total. Tools like top and vmstat should give a more complete picture of your memory. With vmstat you can watch free, cache, buffers, and swap conveniently. With top, you can actually do a command line monitor and watch a particular PID. From the taroon-list: If you're running a 32 bit Linux and run out of low memory, it doesn't matter how much high memory you have, the OOM killer will start killing processes off. Since you're running a 64 bit Linux, this should not be the problem. A discussion on stackoverflow.com may be more relevant to your situation. It turns out (according to the discussion) that calling Runtime.getRuntime().exec() on a busy system can lead to transient memory shortages which trigger the OOM killer. If Runtime.getRuntime().exec() or similar calls do not exist in your application, then please skip the following speculation. I've made some comments concerning host resolution at the end of this message which might be helpful. If Runtime.getRuntime().exec() is used, the scenario goes like this: 1. call Runtime.getRuntime().exec() 2. fork() gets called and makes a copy of the parent process 3. System runs a different process At this point you have two processes with largish memory requirements At this point the OOM killer may get triggered 4. exec() gets called on the child process and memory requirements go back down. At least that's how I read the this reference: http://stackoverflow.com/questions/209875/from-what-linux-kernel-libc-version-is-java-runtime-exec-safe-with-regards-to-m Since processes that fork a lot of child processes are high on OOM killer's kill list, Tomcat gets killed. See for example: http://prefetch.net/blog/index.php/2009/09/30/how-the-linux-oom-killer-works/ As to why it would happen on the newer production systems and not the older system, my only idea concerns the version of the kernel you're using. Memory management has been significantly reworked between the 2.4 and 2.6 kernels. If you use a 2.4 kernel on your older system, this could explain some of the differences with memory allocation. So, if Runtime.getRuntime().exec() is used, what are some possible solutions? 1. Reducing Xms, Xmx while adding physical memory If you do this, then the fork() call without the exec() being called directly afterwards won't be as expensive. Your application will be able to serve more clients without potentially triggering the OOM killer. Garbage collection may be an issue if this is done, so tuning with JMeter is probably a good idea. 2. Create a lightweight process that forks what Runtime.getRuntime().exec() calls and communicate with the process over sockets. This is pretty unpleasant, but you might be able to treat this as a remote process server. You could then end up using a custom object, JNDI lookups, and pooling, much like database pooling. As I've said, this is all based on an assumption that the application is requesting a transiently large amount of memory caused by Runtime.getRuntime().exec() or other similar action. If this is not the case, then the above arguments are null and void. DNS Thoughts As for the ideas concerning DNS - I've never seen DNS issues actually take down an environment. However, I've seen orders of magnitude performance issues caused by poorly configured DNS resolution and missing DNS entries. One way to test DNS performance issues is to set up a client with a static IP address, but don't put it in your local DNS. Then run JMeter on this client and stress your server. Finally, add the client into DNS and stress your server with JMeter. If you notice a difference, then there are some issues with how your server uses host resolution. Make sure that nonexistent address resolution services (nisplus, nis, hesiod) are not listed as sources on the host line in /etc/nsswitch.conf (or wherever Slackware puts it). At least put a [NOTFOUND=return] entry after dns but before all the other services listed on the hosts: line of the nsswitch.conf file. So, here's a summary to all of this rambling: 1. Monitor memory with vmstat and top to get a better picture of the system memory 2. If Runtime.getRuntime().exec() is used, then transient memory allocations could trigger the OOM killer on a busy system 3. Make sure host resolution works properly, and turn it off in server.xml OK, enough rambling - hope this is useful. /mde/ --- On Wed, 2/3/10, Carl c...@etrak-plus.com wrote: From: Carl c...@etrak-plus.com Subject: Re: Tomcat dies suddenly To: Tomcat Users List users@tomcat.apache.org Date: Wednesday, February 3, 2010, 5:07 PM Chris, Interesting idea.

Re: Mod_JK connector configuration Error

Carl was using 32-bit Linux, which he isn't :( Correct, which made the whole point moot, so I'm not sure why Dan even brought it up. I just mentioned the 32-bit Linux behavior for completeness. I did state that I realized 32-bit Linux is not in play. AFAIK, 64-bit Linux has a wide-open memory addressing scheme. Maybe it considers everything under 17 billion GiB to be low memory, now :) No, the hardware restrictions don't exist in 64-bit mode. This is what I've read as well. If you use 64-bit Linux, this problem goes away. There are also some ways to build the 32-bit kernel in order to reduce this problem. All this is moot since a 64-bit Linux kernel is being used. As to the copy-on-write behavior for fork()d processes, it would help if I read the man pages: Under Linux, fork() is implemented using copy-on-write pages, so the only penalty that it incurs is the time and memory required to duplicate the parent’s page tables, and to create a unique task structure for the child. It turns out that things are a little bit more complicated than that, in that since version 2.3.3 fork is actually a wrapper to clone(2) with the appropriate flags to give the same result as a traditional fork(2) call. All of this is moot however if there is no Runtime.exec() call in the application. I'm a bit curious though about several points: 1. The application runs fine on an older system. Do we have the glibc and kernel versions for all systems? 2. Different usage patterns (?) seem to cause the outages at different rates (if I remember an account of one Friday). What paths in the application were being exercised most heavily during that time?

The old system: P4. 1GB memory, 1.3GB swap. Uses swap on a regular basis. kernel is 2.4.25. Java is 1.5.0_01-b08. Tomcat is 5.5.23. Glibc is version 2.3..1. New systems: Server A (Dell T110) is a Xeon 3440, sever B (Dell T105) is an AMD. A has 4GB memory and 19GB swap which is never used. B has 6GB memory and 10GB swap which is never used. A and B both use kernel version 2.6.29.6, Java 1.6.0_18-b07 and Tomcat 6.0.24.. Glibc version is 4.3.3 for both A and B. A couple of observations here: Both the old new kernels end in odd numbers. From memory, I thought the odd kernel numbers were experimental, while the even numbers were production or mainline. I don't remember when this numbering system took place, but certainly by the time the 2.6 kernels were released. From kernel.org, I didn't see a 2.6.29 release marked as stable. The thread implementation has changed between the 2.4 and 2.6 kernels. You can see the thread implementation change by running: getconf GNU_LIBPTHREAD_VERSION I'd be interested in knowing the result of that and getconf GNU_LIBC_VERSION on both systems, since I don't recognize 4.3.3 as a glibc version (latest stable is 2.11.1, so I'm assuming 2.4.3.3?). glibc has some thread bugs that were fixed, but not until 2.8 or 2.9. There was also a persistent bug for 32-bit systems that bites Java applications (not your concern since you're running 64-bit) that wasn't fixed until 2.10.1. So in short, I'm guessing this may be a glibc NPTL issue. There are some observations that don't match, in that you're using Java 6 (most problems are reported with Java 1.4 and Java 5), and that you've used OpenSuSE (kernel, glibc version?) with the same Tomcat failure. However: For some of the earlier 2.6 kernels, you could get around NPTL problems by setting this environment variable: export LD_ASSUME_KERNEL=2.4.1 which forces the use of the old linuxthreads model. I don't know if that option is available with the 2.6 kernel that you are using. Another work-around has been posted on the Java bugs forum, albeit for a different threading problem and Java 5: -XX:ParallelGCThreads=1 sets GC to single threads. It's not fixed in the Java bugs database, because later versions of RedHat Linux don't exhibit the SIGSEGV problem. Some people report that single-threading GC solves their problems, while other people report that it doesn't. Some things to try I guess: 1. export LD_ASSUME_KERNEL=2.4.1 (maybe in startup.sh?) if your kernel supports this.. 2. set -XX:ParallelGCThreads=1 in catalina.sh (JAVA_OPTS). This is an experimental switch, not documented here: http://java.sun.com/javase/technologies/hotspot/vmoptions.jsp, but documented here: http://java.sun.com/javase/technologies/hotspot/gc/gc_tuning_6.html 3. Move to an even-numbered kernel with a glibc of 2.10.1 or better. 2.10 might be OK for your environment since the bug fixed in 2.10.1 causes problems for 32-bit systems only. just my two cents . . . . /mde/ - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

Re: Log4j logging doesn't work when a web application is moved outside Tomcat/webapps directory
I just hacked together a quick example on Windows/XP Professional. I imagine it
will work the same way on my Linux machine.
Environment:
OS: Windows/XP Professional - all the latest patches
Java: 1.6.0_20 from Sun
Tomcat: 6.0.26
IDE:NetBeans 6.8
I am reworking the Spring Developer's Notebook bike store example, so I can
understand Spring testing and using mock objects. I've run into a lot of
interesting issues, mostly having to do with Spring test libraries versus
Junit versus mock objects. However, that's a topic for another discussion.
At any rate, I set up the following system:
Tomcat location: C:\Apache\apache-tomcat-6.0.26
localhost webapps: C:\Apache\apache-tomcat-6.0.26\webapps
foo webapps: C:\Apache\hosts\foo-hosts\webapps
bar webapps: C:\Apache\hosts\bar-hosts\webapps
I like to put my virtual hosts outside of the Tomcat directory tree. That way,
when I upgrade Tomcat I don't have to worry about virtual host applications.
Next, I duplicated the Host/Host node in server.xml for the foo and bar
hosts. The resulting Host/Host nodes from my server.xml are shown below.
Host name=localhost appBase=webapps
unpackWARs=true autoDeploy=true
xmlValidation=false xmlNamespaceAware=false
/Host
Host name=foo appBase=C:/Apache/hosts/foo-host/webapps
unpackWARs=true autoDeploy=true
xmlValidation=false xmlNamespaceAware=false
/Host
Host name=bar appBase=C:/Apache/hosts/bar-host/webapps
unpackWARs=true autoDeploy=true
xmlValidation=false xmlNamespaceAware=false
/Host
Note that I didn't change any of the logging prefixes and suffixes, so all
common logging gets mixed together. Since this is just a proof of concept, I
don't really mind.
Next, I copied manager.xml from conf/Catalina/localhost to conf/Catalina/foo,
and conf/Catalina/bar.
I also copied the manager and ROOT web applications to foo-host\webapps and
bar-host\webapps (full path above). It's nice to have a generic welcome page on
test hosts just to make sure your servers are running. The manager application
is useful as well, although I can just copy war files around.
Finally for my setup, I added 127.0.0.1 foo and 127.0.0.1 bar to my hosts file
in WINNT\system32\drivers\etc (this is an upgraded Windows/2000 Professional
machine).
Upon starting up this mess, all three hosts were visible at localhost:8080,
foo:8080, and bar:8080 as you would expect.
I then took the web application, and created three war files. The only
difference in each of the war files was the location of the log file. An
example is shown below.
### direct messages to file dnb-02.log ###
log4j.appender.file=org.apache.log4j.FileAppender
log4j.appender.file.File=${catalina.home}/logs/dnb-02.log
log4j.appender.file.layout=org.apache.log4j.PatternLayout
log4j.appender.file.layout.ConversionPattern=%d{ABSOLUTE} %5p %c{1}:%L - %m%n
### set log levels - for more verbose logging change 'info' to 'debug' ###
log4j.rootLogger=warn, file
### Spring Framework logging
log4j.logger.org.springframework=info
For the other two war files, I just changed dnb-02.log to foo-dnb-02.log and
bar-dnb-02.log.
I really should use a different environment variable and pass it in via
JAVA_OPTS. That way I can set it easily in my IDE to do testing that will
include logging.
I then used the Tomcat manager on all three virtual hosts to load up the
appropriate applications.
To test, I caused different warnings to be logged in different virtual hosts,
then grepped the logs for the results.
As expected, I got three different log files, and the warnings (along with time
stamps) were in the right log files.
Note that I do not have any non-Tomcat jar in apache-tomcat-6.0.26 besides JDBC
jars at this point.
Just for completeness - here's the web.xml:
?xml version=1.0 encoding=UTF-8?
web-app version=2.5

RE: Tomcat 6 error compiling JSPs with nested @include directives
It also sounds like that there are CVS version control files in the deployment. While I cannot think of any security issues with this on a servlet container, there are known problems with this model when doing straight web development. I can think of two variations to your development process that would address the issue. 1. Do a CVS export of the project you are working on when you're ready to test in a servlet container. This means that you will have to check in potentially buggy code to the CVS server. In a multi-developer environment this may or may not be acceptable. 2. Use a private branch for your changes, then work on that branch (checking in, and exporting). Using branches will keep you from adding potentially broken code to the main line. It's also a great way to try out and abandon new ideas without foregoing the advantages of SCM. I also find that I don't need to run a web application in a servlet container as often if I make use of JUnit, EasyMock (or another mock solution), and the Spring test jars (if I'm working with Spring). The only times I run things in a servlet container are for integration testing and JSP - heavy applications. This is a bit far from the Tomcat core subject, but I agree with Chuck. Set up the correct environment when doing development and testing. This makes software release management and deployment much easier, and you're much less likely to break production environments. just my two cents . . . /mde/ --- On Wed, 5/5/10, Caldarale, Charles R chuck.caldar...@unisys.com wrote: From: Caldarale, Charles R chuck.caldar...@unisys.com Subject: RE: Tomcat 6 error compiling JSPs with nested @include directives To: Tomcat Users List users@tomcat.apache.org Date: Wednesday, May 5, 2010, 6:35 AM From: Nuno Faria [mailto:nuno.m.fa...@gmail.com] Subject: Re: Tomcat 6 error compiling JSPs with nested @include directives That would be a pain because I develop and maintain over 20 apps in a CVS system and would force major changes on the dir estructure for our development environments.

Date: Thursday, May 13, 2010, 12:55 PM
Hello -
I have a DB2-backed legacy app on a legacy platform that
I'm trying to modernize. My objective is to modernize
the platform underneath the app (Gentoo Linux for now,
Tomcat 6.0.26, Sun JDK 1.6.0.20) and do so in a way that a
longtime Java/Tomcat integrator would readily recognize (I'm
not one). App uses Hibernate and c3p0; Hibernate is
packaged in the app's war but c3p0 is not; I've installed
c3p0 through Gentoo's usual package management system.
I've also brought in the jar for the proper version of IBM
DB2 JDBC driver and its corresponding license jar to match
the DB2 instance version (versioning between DB2 and JDBC
driver are tightly coupled).
On the legacy Tomcat 5.0 / JDK 1.5 platform, the database
connection configuration info is handled in a seemingly
customized way - something to do with virtual hosts.
At the top of the Tomcat-instance-wide server.xml file is
this structure:
!DOCTYPE web-app[
!ENTITY vhosts SYSTEM vhosts.xml
]
But for now, I'm not interested in dealing with any kind of
virtual host arrangement. The impetus behind that was
so that users can run two independent sessions of the app in
two separate browser tabs or windows .
In the vhosts.xml file is info that looks like it ought to
belong in the app's context.xml file. I understand
that how context sections are written have changed since 5.0
and I *think* I've got that worked out.
The app's original MANIFEST.MF file has this in it:
Classpath:
WEB-INF/classes/mycapp/resource
WEB-INF/classes/myapp/resource
/tld
WEB-INF/classes/elms/resource/hbm/MYAPP
So: given a working platform and after deploying the
app war that I've been given (let's call it myapp.war),
here are the post-deploy steps I've worked out so far:
* Create a symlink for
$CATALINA_BASE/webapps/myapp/WEB-INF/lib/c3p0.jar to where
the package manager has put c3p0.jar
* Create symlinks for db2jcc.jar and db2jcc_license_cu.jar
in $CATALINA_BASE/webapps/myapp/WEB-INF/lib to where I've
put them under /usr/src
* Generate a new
$CATALINA_BASE/webapps/myapp/META-INF/context.xml (see
below) and symlink
$CATALINA_BASE/conf/Catalina/localhost/myapp.xml to it
* Add the following to
$CATALINA_BASE/webapps/myapp/WEB-INF/web.xml, before the
closing /web-app:
resource-ref
descriptionDB connection pool for
MYAPP/description
res-ref-namejdbc/myappqa/res-ref-name
res-typecom.mchange.v2.c3p0.ComboPooledDataSource/res-type
res-authContainer/res-auth
/resource-ref
I've created a context.xml that looks like:
Context
docBase=${catalina.home}/webapps/myapp path=
reloadable=false
Resource name=jdbc/myappqa
description =
MYAPP connection pool
auth=Container
type=com.mchange.v2.c3p0.ComboPooledDataSource

brevity applied - more parameters set
.

/Context
I've been able to browse to the app and get a login page,
but things explode at login attempt, i.e., first attempt to
access the data source.
Question 1: For this to work, do I need to add
WEB-INF/lib to the Classpath: list? There are
about 80 jar files (including log4j, ftpbean, Hibernate) in
there aside from the symlinks I've added for the c3p0, JDBC
driver, and license jar files.
Question 2: In my context.xml, is that one parameter
supposed to be driverClass or driverClassName?
I've seen both used seemingly for the same purpose.
Question 3: Some customization has been done
involving hibernate.properties which I don't think is
necessarily causing a problem (its meat has been replaced
by a reference to another file much like server.xml), but in
there I've noticed this:
property
name=hibernate.connection.pool_size15/property
As I understand it, setting this parameter activates
Hibernate's own connection pooler and further that
Hibernate's own connection pooler is not supposed to be used
in any capacity other than learning and testing. Does
having this setting be in here mean that this app was built
(intentionally or not - likely not) to use Hibernate's
connection pooler and c3p0 end-to-end?
Thanks in advance
Re: Porting app from Tomcat 5.0.28 to 6.0.26
I'm not familiar with the earlier versions of Hibernate, so I can't reliably comment. However, the principles should be the same even if some of the names have changed. If you are relying on Hibernate for database connections and database pooling, then you'll want to put all of that information into the Hibernate configuration files and none of it in META-INF/context.xml and WEB-INF/web.xml. Just a quick skim of the documentation at http://simoes.org/docs/hibernate-2.1/reference/html/index.html and a forum message concerning cp30 configuration doesn't reveal any name changes, but your mileage may vary. Also, according to the migration document found at http://community.jboss.org/wiki/HibernateCoreMigrationGuide30, there are a lot of code changes between Hibernate 2 and Hibernate 3, but apparently no configuration changes. Hopefully, the c3p0 / Hibernate managed database connection configuration given at the bottom of the Wiki page should work for Hibernate 2.x. just my two cents . . . . /mde/ --- On Fri, 5/14/10, Jeff Hubbs jhubbsl...@att.net wrote: Also, this wiki says Hibernate ships with the CP30 connection pooling classes, so as long as the Hibernate jars are in WEB-INF/lib directory (which they should be), they should be available.

Re: sneaky JDBC connection (was: THANK YOU ALL for help)
I apologize to the list, the last message got truncated and sent. I hit return
twice while editing in Yahoo (normally edit off-line).
OK - for the database leak.
Use try / catch / finally blocks around all connection code (Hibernate or
otherwise). I think someone posted boilerplate code to the list not too long
ago.
// try catch finally pseudocode
// review and use at your own risk
Session session = HibernateUtil.getSessionFactory.openSession();
Transaction tx = null;
try {
tx = session.beginTransaction();
// do your database stuff here
tx.commit();
}
catch (Exception e) {
if (tx != null) {
tx.rollback();
}
// do something meaningful here - log and recover
}
finally {
if (session != null) {
session.close();
}
The Hibernate documentation advocates using filters to get and close sessions,
especially if you're using a secondary cache.
Secondly, there have been some permgen leaks fixed in the latest versions of
the MySQL JDBC driver. Make sure you're using 5.1.12 (latest version). 5.1.11
fixed a permgen leak from java.util.Timer.
Here's the permgen leak bug notation:

it's lazily created if need be per-instance, and torn down when
the connection is closed.
Again, sorry for the earlier message.

Re: problems at thejarbar.org
I think you are running into a MySQL database connection timeout. You can use a MySQL admin interface (command line, PHPAdmin, MySQL Workbench, etc.) to verify the idle connection timeout limit. There have been comments on the web concerning this. One such discussion and a solution are here: http://lists.mysql.com/java/6578 The explanation of the parameters given in the above link can be found here: http://dev.mysql.com/doc/refman/5.0/en/connector-j-reference-configuration-properties.html Based on those two references, you'll need to modify your Realm database URL: connectionURL=jdbc:mysql://localhost:3306/yucca123_thejarbarautoReconnect=truereconnectAtTxEnd=true Note, I have not tried this, so test before production. The other solution mentioned is to use a DataSource Realm. This requires you to configure a JNDI datasource describing your database connection as well as the DataSource Realm. You can add all of this information in your web application's META-INF/context.xml file if it's application-specific. If this is a host or service-based definition, then you'll have to define the JNDI resources in a GlobalNamingResources element. See the following: http://tomcat.apache.org/tomcat-6.0-doc/config/globalresources.html Note the warning that this resource will not be available to an individual web application unless you use a ResourceLink in your META-INF/context.xml file. See the globalresources link above for an example. Since you're using this connection for container managed authentication and authorization, I'm not sure why your web application would need access to this resource. However, it's 3 am, so I may have missed a few points that Chuck, Charles, or Pid will be happy to correct. To summarize - it seems the easiest fix is to add the following properties to your JDBC url: autoReconnect=true reconnectAtTxEnd=true Add them to the end of the URL, connected with ampersands. I hope this gets you up and running. . . . . . just my two cents /mde/ --- On Sun, 5/30/10, Yucca Nel yucca...@live.co.za wrote: From: Yucca Nel yucca...@live.co.za Subject: Re: problems at thejarbar.org To: Tomcat Users List users@tomcat.apache.org Date: Sunday, May 30, 2010, 9:34 AM Yes, but I am using JDBC and followed the setup step by step from tomcat docs ?xml version=1.0 encoding=UTF-8?

Re: problems at thejarbar.org
Chris, based on what you're saying and the server.xml posted earlier in this thread, the following should be done? 1. Remove the JDBCRelm from the Engine node 2. Create a GlobalNamingResources Resource entry with the following: Resource name=jdbc/auth description=The Jar Bar user authentication type=javax.sql.DataSource auth=Container driverClassName=com.mysql.jdbc.Driver maxActive=10 maxIdle=3 maxWait=1 password=MyPassword url=jdbc:mysql://localhost:3306/yucca123_thejarbar validationQuery=/* ping */ SELECT 1 username=MyUser/ This is basically what I would normally put in the context.xml file of a web application for an application-specific database connection. 3. Then create a DataSource Realm under the Engine node to replace JDBCRealm. Realm className=org.apache.catalina.realm.DataSourceRealm userTable=users userNameCol=user_name userCredCol=user_pass userRoleTable=user_roles roleNameCol=role_name dataSourceName=jdbc/auth It was a little unclear to me from the documentation that I could put all of the resource attributes in a GlobalNamingResources Resource entry. It was also a little unclear to me that I could just refer to a global resource name with dataSourceName in the Realm.

Don't use autoReconnect as a parameter to the JDBC driver. Instead, use the validationQuery on the connection pool to have the pool verify that the connection is still valid. MySQL Connector/J even supports a ping query that can gracefully fall-back to driver versions that don't support it. I highly recommend that you: 1. Use a Tomcat-configured DataSource 2. Use a DataSourceRealm coupled with #1 3. Tell Hibernate to use #1 That way, all your db configuration is in one place. Add this parameter to your DataSource configuration (it configures the connection pool): validationQuery=/* ping */ SELECT 1 This will cause the connection pool to execute that query every time a connection is requested from the pool, just to verify that it's properly connected.

[OT] Re: problems at thejarbar.org
Chris, I think it all depends what you need your Realm to manage. In this instance (single application on Tomcat), then it probably doesn't matter if the Realm sits at the application, Host, or Engine level. Like you've pointed out before it's nice to have a self-contained application with all of the database configurations in one spot. Having some database configurations in META-INF/context.xml, and others in Tomcat's server.xml seems to be a maintenance / migration challenge waiting to happen. If you have multiple applications using the same Realm information, then it might make sense to move the Realm to a Host or Engine level. However I cannot think of a good use case off the top of my head to potentially run multiple hosts under one Engine with the same authentication Realm . . . . Maybe a better place to document all of this and some use case scenarios would be the Wiki. Since I'm thinking about this, I'll see what I can cobble up in the next few days.

Re: hibernate not finding global resource datasource defined by tomcat
Please read the following for a detailed description on how to configure Hibernate to use JNDI resources supplied by Tomcat. http://wiki.apache.org/tomcat/TomcatHibernate Then you will need a ResourceLink element in META-INF/context.xml to make the resource in GlobalNamingResources available to your application. The configuration for that information can be found here: http://tomcat.apache.org/tomcat-6.0-doc/config/context.html#Resource%20Links Finally, unless you place Tomcat's manager and admin application's authentication and authorization information in your database, removing the UserDatabaseRealm from GlobalNamingResources will prevent you from using the manager and admin application. You can place more than one Resource element in the GlobalNamingResources element of your server.xml. I'm trying to finish up a document on DataSourceRealms.

If you're running as a service, why don't you make use of --StdOutput and
--StdError as documented here:
http://tomcat.apache.org/tomcat-6.0-doc/windows-service-howto.html
Also, if you're running as a service, the Tomcat Monitor allows you to change

Hi All,
Before we upgraded from Tomcat 6.0.18 to 6.0.26 I was able
to redirect
stdout/stderr of tomcat.exe using the following Python
code;
from subprocess import Popen
logfile = open('tomcat.log', 'w')
p = Popen(r'C:\Program Files\Apache Software
Foundation\Tomcat
6.0\bin\tomcat6.exe', shell=True, stdout=logfile,
stderr=logfile)
but with 6.0.26, the above code fails to redirect the
output to tomcat.log,
all of the output goes to the console (cmd.exe).
Has something changed in 6.0.26 (Windows) that would effect
this behaviour ?
Cheers

Re: No members active in cluster group
A quick question:
Does the Windows Server stop multicast packets? I was exploring clustering
today
on Fedora 13, and I had to modify my firewall rules to allow multicast.
Here's a nice tool from an earlier thread about clustering. If you run this on
your local machine you should see messages.
See the thread: http://marc.info/?t=10831889571r=1w=4
And for the tool, see this particular mail message:
http://marc.info/?l=tomcat-userm=108319193624084w=4
Another thing to look out for is broadcasting to 127.0.0.1. From the document
at
http://tomcat.apache.org/tomcat-6.0-doc/cluster-howto.html
3. The IP broadcasted is java.net.InetAddress.getLocalHost().getHostAddress()
(make sure you don't broadcast 127.0.0.1, this is a common error)
Hope this helps.

Re: Is FarmWarDeployer is working?
Shammi, I have something working for 3 Tomcat 6.0.29 nodes on Fedora 13 using Sun JRE/JDK 1.6.0_21. I've not tried undeploying a web application yet. Here's what I've found so far on Tomcat 6.0.29. 1. You have to place the Cluster node under the Host element. Tomcat 6.0.29 complains that the element Cluster/Deployer element is not understood at the Engine level. 2. One node needs to have watchEnabled=true, all other nodes watchEnabled=false 3. deployDir is the same as appBase This last is a guess, but it seemed logical (and works). Based on my reading of the scant documentation, the war file gets deployed there for Tomcat to run (hence the deployDir name). There is some noise in the documentation about deploying ROOT in this fashion, but I've not experimented with that yet. I've not read the javadoc (yet) nor looked through the source code (on my list of things to do). So basically, here's my Deployer configuration for a three node cluster running on one machine (fronted by Apache and load balanced via mod_jk). Deployment node: a. Change the [name] to fit your implementation or leave out the Alias elements. b. Change $CATALINA_BASE/name to be your absolute path to the directory Host name=localhost appBase=webapps unpackWARs=true autoDeploy=true xmlValidation=false xmlNamespaceAware=false Alias[a-host-name]/Alias Alias[another-host-name]/Alias !-- cluster must go here in order to use farm deployment -- Cluster className=org.apache.catalina.ha.tcp.SimpleTcpCluster Deployer className=org.apache.catalina.ha.deploy.FarmWarDeployer tempDir=$CATALINA_BASE/temp-dir/ deployDir=$CATALINA_BASE/webapps/ watchDir=$CATALINA_BASE/watch-dir/ watchEnabled=true/ /Cluster /Host Other nodes: a. Same notes apply - change [name] to suit your implementation or leave out Alias b. Replace $CATALINA_BASE with the absolute path to the directory Host name=localhost appBase=webapps unpackWARs=true autoDeploy=true xmlValidation=false xmlNamespaceAware=false Alias[a-host-name]/Alias Alias[another-host-name]/Alias !-- cluster at host level for farm deployment -- Cluster className=org.apache.catalina.ha.tcp.SimpleTcpCluster Deployer className=org.apache.catalina.ha.deploy.FarmWarDeployer tempDir=$CATALINA_BASE/temp-dir/ deployDir=$CATALINA_BASE/webapps/ watchDir=$CATALINA_BASE/watch-dir/ watchEnabled=false/ /Cluster /Host I haven't tried this on the subversion trunk, and I've seen some recent commits to the clustering components.

First time I am using FarmWarDeployer. I only knows that using this we can deploy our application in one node in the tomcat cluster rather than deploying in all the nodes. Unfortunately, there isn't much documentation on the FarmWarDeployer. Here's what I've been able to find: http://tomcat.apache.org/tomcat-7.0-doc/cluster-howto.html ...which gives a configuration example: Deployer className=org.apache.catalina.ha.deploy.FarmWarDeployer tempDir=/tmp/war-temp/ deployDir=/tmp/war-deploy/ watchDir=/tmp/war-listen/ watchEnabled=false/ It also says: The default tomcat cluster supports farmed deployment, ie, the cluster can deploy and undeploy applications on the other nodes. The state of this component is currently in flux but will be addressed soon. There was a change in the deployment algorithm between Tomcat 5.0 and 5.5 and at that point, the logic of this component changed to where the deploy dir has to match the webapps directory. For more info, Please visit the reference documentation I suspect the phrase the cluster in the first sentence really means one particular node in the cluster. The reference documentation mention at the end is currently blank :( There is also, of course, the javadoc: http://tomcat.apache.org/tomcat-7.0-doc/api/org/apache/catalina/ha/deploy/FarmWarDeployer.html The documentation seems all messed-up: The javadoc says deployDir - the directory where we watch for changes and applicationDir - the directory where we install applications but it's clear that the former is where the apps are installed, the latter is fictional, and the real watch directory is called watchDir. Then after some reading what I did is : I created /tmp/war-deploy , /tmp/war-app , /tmp/war-listen and /war-temp directories. Good. What is /tmp/war-app for? What does your Deployer element look like? I suspect something
Clustering within a single system
I apologize for the wall of text.
I'm working through the clustering and farm deployment documentation
for Tomcat 6 / Tomcat 7. To that end I've set up a 3 node cluster load
balanced by an Apache web server on a single system.
The environment and configuration particulars are at the end of the mail
message.
Problem summary:
The application is a quick sample that does the following:
1. Form-based login
2. Some personal information that can be customized (session variable)
3. Random pet generated from a pet factory and a properties file (session
variable)
4. Exit message on logout containing the chosen pet and the personalization info
If I pre-deploy the distributable application to all three nodes, I
get reasonable log entries, and the application works as expected.
If I start up Tomcat and then deploy the application to the three
nodes, I get error messages in the logs, and the application is not
available until the last timeout for clustering has expired (default
of 60 seconds). However, once this timeout has passed, clustering
seems to work.
I observe similar problems when using the farm deployer. The application
does not seem to be available until it is deployed across the 3 nodes
and the cluster timeout has passed.
I have not tried these tests in a controlled fashion using Tomcat from
subversion.
So, how do I remove the errors from the logs?
. . . . just my two cents.
/mde/
Sequence of events which works cleanly:
1. Copy the RPets.war file to each of the three $CATALINA_BASE/webapps
directories
2. Start up each Tomcat instance - wait 5 seconds between startups so
ports can be chosen for clustering (I could configure these)
3. Test the application

And messages are written into catalina.out file.
I would like to write cluster messages in a cluster.out file but in the

Re: DB connection error and broken images while changing webapp context path
Astghik, As has already been pointed out: 1. Don't put Context elements in server.xml - use either: a. META-INF/context.xml in your web application b. $CATALINA_HOME/conf/Catalina/[hostname]/[application].xml 2. Don't use docBase in your Context element. Tomcat will figure that out 3. Don't use subdirectories of one appBase as the appBase for another host - this will probably get you double deployment. If you want your application to be known as both http://localhost:8080/ and http://my.ip.com:8080/ then you can do the following: 1. Rename your war file ROOT.war. This is the name used for the root application 2. Add an Alias element to your original Host element - something like this: Host name=localhost appBase=webapps unpackWARs=true autoDeploy=true xmlValidation=false xmlNamespaceAware=false Aliasmy.ip.com/Alias /Host From your path statements, it looks like you're using the default Ubuntu-distributed Tomcat (and maybe OpenJDK)? This has led to some problems in the past. I recommend downloading the latest tar.gz of Tomcat 6 (6.0.29) from tomcat.apache.org, and the latest version of Java (1.6.0_21) from Oracle/Sun for your platform. If you're having trouble getting Hibernate to work with Tomcat, and especially Tomcat's database connection pooling, you might want to see the following Wiki article: http://wiki.apache.org/tomcat/TomcatHibernate If you really are interested in virtual hosts rather than just an Alias, then you might want to see the following Wiki article: http://wiki.apache.org/tomcat/TomcatDevelopmentVirtualHosts Once you get all of this digested, then post your information (Tomcat server version - complete with minor revision numbers, JRE version, OS, server.xml with no comments and sensitive info blanked out, web.xml from your application, hibernate.cfg.xml, Spring configuration files, and where your images are located in your web application structure) if you're still stuck.

Re: JNDI: LDAPv3 with StartTLS
A couple of things come to mind: Could this be a remote firewall issue? If you have an LDAP client that can go against your server, that would answer that question. I did a quick search, and there are a lot of messages concerning Debian and java.net.SocketException: Network is unreachable messages. The underlying theme seems to be IPv6. Although I didn't see any IPv6 listings in your netstat command, you might try adding -Djava.net.preferIPv4Stack=true to JAVA_OPTS (make a file called setenv.sh in $CATALINA_HOME/bin and set it). Other than that, I'm just guessing at this point. . . . . just my two cents. /mde/ - Original Message From: Igor Galić i.ga...@brainsware.org To: Tomcat Users List users@tomcat.apache.org Sent: Sun, August 15, 2010 9:28:31 AM Subject: Re: JNDI: LDAPv3 with StartTLS This is getting out of hand... i.ga...@pheme /opt/tomcat6 % sudo netstat -nalpt | grep -w LISTEN|grep 80 tcp0 0 0.0.0.0:80880.0.0.0:* LISTEN 30503/traffic_manag tcp0 0 0.0.0.0:80910.0.0.0:* LISTEN 30513/traffic_serve tcp0 0 127.0.0.1:8000 0.0.0.0:* LISTEN 17112/httpd-prefork tcp0 0 127.0.0.1:8001 0.0.0.0:* LISTEN 16454/httpd-worker tcp0 0 0.0.0.0:80 0.0.0.0:* LISTEN 30503/traffic_manag tcp0 0 0.0.0.0:80810.0.0.0:* LISTEN 30503/traffic_manag tcp0 0 0.0.0.0:80830.0.0.0:* LISTEN 30503/traffic_manag tcp0 0 0.0.0.0:80840.0.0.0:* LISTEN 30513/traffic_serve i.ga...@pheme /opt/tomcat6 % java -version java version 1.6.0_21 Java(TM) SE Runtime Environment (build 1.6.0_21-b06) Java HotSpot(TM) 64-Bit Server VM (build 17.0-b16, mixed mode) i.ga...@pheme /opt/tomcat6 % sudo rm -rf logs/* i.ga...@pheme /opt/tomcat6 % sudo /etc/init.d/tomcat6 start Starting Tomcat6 Container: :Using CATALINA_BASE: /opt/tomcat6 Using CATALINA_HOME: /opt/tomcat6 Using CATALINA_TMPDIR: /opt/tomcat6/temp Using JRE_HOME:/usr/lib/jvm/java-6-sun/jre Using CLASSPATH: /opt/tomcat6/bin/bootstrap.jar i.ga...@pheme /opt/tomcat6 % less logs/catalina.out Aug 15, 2010 4:25:30 PM org.apache.coyote.http11.Http11Protocol init SEVERE: Error initializing endpoint java.net.SocketException: Invalid argument at java.net.PlainSocketImpl.socketBind(Native Method) at java.net.PlainSocketImpl.bind(PlainSocketImpl.java:365) at java.net.ServerSocket.bind(ServerSocket.java:319) at java.net.ServerSocket.init(ServerSocket.java:185) at org.apache.tomcat.util.net.DefaultServerSocketFactory.createSocket(DefaultServerSocketFactory.java:56) at org.apache.tomcat.util.net.JIoEndpoint.init(JIoEndpoint.java:540) at org.apache.coyote.http11.Http11Protocol.init(Http11Protocol.java:176) at org.apache.catalina.connector.Connector.initialize(Connector.java:1014) at org.apache.catalina.core.StandardService.initialize(StandardService.java:680) at org.apache.catalina.core.StandardServer.initialize(StandardServer.java:795) at org.apache.catalina.startup.Catalina.load(Catalina.java:524) at org.apache.catalina.startup.Catalina.load(Catalina.java:548) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at org.apache.catalina.startup.Bootstrap.load(Bootstrap.java:261) at org.apache.catalina.startup.Bootstrap.main(Bootstrap.java:413) Aug 15, 2010 4:25:30 PM org.apache.catalina.startup.Catalina load SEVERE: Catalina.start LifecycleException: Protocol handler initialization failed: java.net.SocketException: Invalid argument at org.apache.catalina.connector.Connector.initialize(Connector.java:1016) at org.apache.catalina.core.StandardService.initialize(StandardService.java:680) at org.apache.catalina.core.StandardServer.initialize(StandardServer.java:795) at org.apache.catalina.startup.Catalina.load(Catalina.java:524) at org.apache.catalina.startup.Catalina.load(Catalina.java:548) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at org.apache.catalina.startup.Bootstrap.load(Bootstrap.java:261) at org.apache.catalina.startup.Bootstrap.main(Bootstrap.java:413) Aug 15, 2010 4:25:30 PM
Re: JNDI: LDAPv3 with StartTLS
Reading your original request, you're using an external certificate to go
against your LDAP server, right?
If so, you might try using Felix's code, and then adding
authentication=EXTERNAL to the Realm configuration.
Your JNDIRealm configuration would then end up looking like:
Realm className=org.apache.catalina.realm.JNDIRealm
connectionURL=ldap://mail.brainsware.org:389/;
alternateURL=ldap://mail.esotericsystems.at:389;
commonRole=admin
connectionName=uid=whatever
connectionPassword=securityisgreat.
userBase=ou=people,dc=brainsware,dc=org
userPattern=(uid={0})(postOfficeBox=internal_projects)
startTLS=true
authentication=EXTERNAL
userSearch=(uid={0}) /
That is, if I'm reading the StartTLS tutorial, Realm configuration docs, and
org.apache.catalina.realm.JNDIRealm.java code correctly . . .
Another approach to using Felix's code is to create a separate class, put it
in
a jar, and then add that jar to $CATALINA_HOME/lib. You'll have to add an
MBeans descriptor as well. How to do all that is documented:
(Realm) http://tomcat.apache.org/tomcat-6.0-doc/realm-howto.html#Overview
(MBeans) http://tomcat.apache.org/tomcat-6.0-doc/mbeans-descriptor-howto.html
That way you'll have a generic Tomcat instead of a patched version.

Re: Installation problem [newbie]
A couple of things: The list in general strips attachments, so your log did not make it through. The file httpd-2.2.16-win32-x86-openssl-0.9.8o.msi is for installing the Apache web server. The Apache web server is useful if you are planning to write PHP, Perl, Python, or Lisp/Scheme web sites. The file apache-tomcat-6.0.29.exe is the file for installing Apache Tomcat as a service on Windows. Tomcat is useful if you are planning to write Java web sites. If you run Tomcat on Windows as a service, the installer will figure everything out. The service installation is good enough for many uses. Documentation for service installation is here: http://tomcat.apache.org/tomcat-6.0-doc/setup.html#Windows Documentation for managing the service under Windows is here: http://tomcat.apache.org/tomcat-6.0-doc/windows-service-howto.html If you are going to actively develop Java web applications, then it's sometimes useful to install from the zip archive. Many IDEs use the batch files from the zip archive to start and stop Tomcat. Just unzip the archive in a directory that you have read/write access to. Add an environment variable called JAVA_HOME and point it to your installation of the Java JRE. On Windows the JRE is usually located in C:\Program Files\Java\jre6 (for the latest versions of Java). Now to run the unzipped version of Apache Tomcat, just open a DOS command window, navigate to the bin directory under where you unpacked the zip file. For example, if you unpacked the zip file in C:\, the bin subdirectory would be in C:\apache-tomcat-6.0.29\bin. Type startup (which will run startup.bat) to start Tomcat, and shutdown (which will run shutdown.bat) to stop Tomcat. To get your IDE to work with Tomcat, it's best to ask on the IDE mailing list (for example, NetBeans or Eclipse). On my XP system, I've installed both. I set the service startup to manual, and I point my IDE (NetBeans) to the zip file installation. . . . . just my two cents /mde/ From: Jonathan Camilleri camilleri@gmail.com To: Tomcat users@tomcat.apache.org Sent: Wed, August 18, 2010 11:17:59 AM Subject: Installation problem [newbie] I ran into an installation problem, and, hope you can help me out with it.

Re: war not redeploying
Are you starting and stopping Tomcat under Cygwin? I've seen some interesting file locking problems (as well as the terminate batch job? question) when running Windows applications under Cygwin. How are you deploying your web application? Are you copying the new war file into $CATALINA_HOME/webapps, using the manager application, or deploying via an IDE? I'm on Linux at the moment, so I can't explore this. However, here are some things you might try. 1. Run everything under DOS. If you're a UNIX person, then this is not going to be as comfortable as running Cygwin, but it will remove some unintended consequences. Or as Konstantin suggested, run things on Linux. 2. Use the manager application for deployment. If you are looking at a command line mechanism for deploying applications to production, you might take a look at the Ant tasks. Documentation for the Ant tasks can be found here: http://tomcat.apache.org/tomcat-6.0-doc/manager-howto.html#Executing_Manager_Commands_With_Ant (sorry for the wrapped line) 3. Use the IDE in a development environment Both NetBeans and Eclipse allow you to deploy to a running Tomcat (and start / stop Tomcat) from within the IDE. In a development environment I find that much more convenient than opening a shell and executing commands. Some quick notes on your web application (which I don't think will affect its loading and unloading): 1. Debug is no longer a valid attribute for the Context element. 2. There appear to be some issues with with your Resource element describing your JDBC connection. 3. Some of the connection pool threads issues could be due to a JDBC driver. If you're using MySQL, make sure you have the latest JDBC driver. Versions before 5.1.11 did cause problems. . . . . just my two cents. /mde/ - Original Message From: Sean McEligot seanmc...@gmail.com To: Tomcat Users List users@tomcat.apache.org Sent: Wed, August 18, 2010 12:04:46 PM Subject: Re: war not redeploying On Wed, Aug 18, 2010 at 11:56 AM, Konstantin Kolinko knst.koli...@gmail.com wrote: 6.0.25 An odd version...

I will certainly not respond to addresses I don't recognize very quickly. Thanks. I'll make comments inline. Well, I've installed the webserver (1st file), however, no services are running, and, no page is running on http://127.0.0.1:8080 (IIS runs on port 80). Which 1st file? If you've installed the httpd-2.2.16-win32-x86-openssl-0.9.8o.msi file, that is not Tomcat. That is the Apache web server which much like IIS (I think it's much better than IIS, but that's my opinion). If you're going to install that, you'll need to switch your IIS server service to manual and shut it down. If you installed apache-tomcat-6.0.29.exe, then you should see the Tomcat Monitor application in your system tray. This can be used to start and stop Tomcat. Make sure you have administrator privileges, and that you've allowed Tomcat / Java in your firewall. When you first run Tomcat, Windows will prompt you for this.

Previously i had tried a simple way; my index.jsp file called itself on form

request.getParameter(txt_userid) + ') AND a.PASSWORD = '+ epass +';
boolean hasdata=false;
java.sql.ResultSet rs = connection.executeQuery(query);
Wow: this is a SQL injection attack just waiting to happen. What happens
if I submit the txt_userid request parameter as ') OR 1; or, even
better, '); DELETE FROM LOGIN_INFORMATION; or some other evil thing?
I believe that certain JDBC drivers will not execute more than one query
per executeQuery() call, but you can't really count on that. It's easy
to use a PreparedStatement and just do it properly: poof! SQL injection
attacks are a thing of the past (unless the driver is broken, but they
test those things very well).
Also, most SQL databases perform case-insensitive string comparisons, so
your LOWER(a.USER_ID) = LOWER(...) can probably be simplified. Note that
it also means you likely have case-insensitive passwords (though you
haven't shown us what epass is -- is could have been hashed.
while(rs.next()) {
hasdata=true;
session.setAttribute(user_id,rs.getString(USER_ID));
session.setAttribute(user_name,rs.getString(NAME));
session.setAttribute(branch_code,rs.getString(BRANCH_CODE));
Re: Best practices for deployment on cluster environment
I haven't tried this in production (yet) so your mileage may vary.
In the cluster setup, there's a FarmDeployer element that can be used to deploy
across the cluster.
The host that does the deploying:
Deployer className=org.apache.catalina.ha.deploy.FarmWarDeployer
tempDir=${catalina.base}/temp-dir/
deployDir=${catalina.base}/webapps/
watchDir=${catalina.base}/watch-dir/
processDeployFrequency=4
watchEnabled=true/
And the hosts that get the web application:
Deployer className=org.apache.catalina.ha.deploy.FarmWarDeployer
tempDir=${catalina.base}/temp-dir/
deployDir=${catalina.base}/webapps/
watchDir=${catalina.base}/watch-dir/
processDeployFrequency=4
watchEnabled=false/
For large web applications and frequent deployments, this might generate a lot
of network traffic.
Also, it's not intuitive (to me) how processDeployFrequency works, but I need
to
look at the code. In any case, you might have the Tomcat doing the deploying
not
actually serving content.
I found out that you can use ${variable.name} in configuration files, so it's
now much easier to clone installations and just edit setenv.sh(bat) as
appropriate.
Hope this helps.

Could you share your experience with this kind of environment? Is this the

way to deal with deployment?
Scripting your deployment process is a Good Idea. It will also mean
that it happens the same every time, according to whatever your scripted
procedure is.
Upload them separately to each server, check integrity and then run a
local script to finish the process and deploy them to appBase do
server restarts if needed.
If you're deploying to production servers with auto-deployment enabled,
make sure the upload occurs to a separate temp location, before copying
it into the appBase.
You could SCP files up to a location on the server, using a user account
configured with a password-free key pair.
SSH will let you limit a given key to specific commands, so the account
could be configured solely for uploading the files then running the
local deployment script.

Weird. I just updated my environment (on Fedora 13) to support 4 Tomcats and it worked as expected.

Re: To JAAS or not to JAAS
As an alternative, maybe you could write an ant script that would add the libraries, read values from a properties file to write the jaas.config file, and populate the database? Copying files with ant is easy, and http://db.apache.org/ddlutils/ makes it pretty easy to dump and recreate databases. Editing jaas.conf with property substitution might be a bit tricky, but possible if your authorization / authentication requirements aren't too complex. The Jetspeed Maven plugin does some similar work as well, but I've found it to be a bit invasive at times. . . . . just some random thoughts. /mde/ From: Gabriele Bulfon gbul...@sonicle.com To: Tomcat Users List users@tomcat.apache.org Sent: Mon, September 13, 2010 2:55:09 AM Subject: To JAAS or not to JAAS Hello, I have a web application written with JAAS authentication, using my own login modules. This is fine as long as the deployment is made by a system administrator who knows how to configure jaas.config and to place needed jars in the tomcat lib directory, following my instructions. Also, JAAS mode requires the sysadmin to prepare the backend db himself with a sql file of mine, and configure the context.xml with db informations. Now, I would like the same web app to be deployable in 2 ways, both with JAAS and without JAAS, to simplify deployment by less experienced deployer who will just put the war file inside webapp and access the application. During the first access I would like the application to understand that is not working in JAAS mode, check for a properties file inside the webapp, that when not existsant will trigger an installation sequence via web (to configure db access and so on). This will create this properties file that will be the reference configuration, substituting the context.xml / jaas config. My simple idea would be to have this war without the context.xml definitions, then have an init parameter of the application in web.xml to define Use Jaas = Yes/No that will let the webapp understand and do what I described.

Are you using connection pooling provided by tomcat? Did you put MySQL driver

Re: Issues with Memory Leaks on Tomcat 6.0.28
I'll do some of this inline:
WARNING: [SetPropertiesRule]{Server/Service/Engine/Host/Context} Setting
property 'debug'
to '0' did not find a matching property.
Two things here:
1. Place your context in a META-INF/context.xml file in your web application,
not in server.xml
2. Remove the debug attribute, since it hasn't been valid for a long time.
WARNING: No rules found matching
'Server/Service/Engine/Host/Context/Logger'.
I don't see a reference to a Logger in the Context documentation for 5.5, 6.0,
0r 7.0. If you're trying to log at the Context level, take a look at the
documents for your version of Tomcat (which you've not mentioned) and add the
appropriate Valve element.
SEVERE: Error listenerStart
This is the problem (as pointed out before). The code you're using in your
Listener isn't working as expected. I suspect that you're trying to start up
iBatis (now MyBatis), and that the code is failing.
SEVERE: The web application [/Simon] created a ThreadLocal with key of type
[java.lang.ThreadLocal] (value [java.lang.threadlo...@3e0d1329]) and a value

[com.ibatis.sqlmap.engine.impl.sqlmapsessioni...@4c650892]) but failed to

remove it when

This is fallout from your failed listener (as has been pointed out).
When you write a listener class, you have both a
contextInitialized(ServletContextEvent sce) and a
contextDestroyed(ServletContextEvent sce) method.
It looks like your contextInitialized method is failing, and you've not written
a contextDestroyed method. You'll need to fix the first, and then write the
second so that when the context is destroyed (like undeploying the
application),
you shut down all of your resources gracefully.
I've not used iBatis, so I am not aware of how the listener should be written.
I've done this for Hibernate.
I'm also guessing that you're setting up iBatis to control the database pooling
and access. You can let Tomcat manage the connection pool with iBatis. This may
simplify your listener code somewhat. An iBatis thread concerning that can be
found here:
http://markmail.org/message/pocthjsiw4cdhohj#query:+page:1+mid:pocthjsiw4cdhohj+state:results
So:
1. Fix your contextInitialized method
2. Write a contextDestroyed method
3. Configure iBatis to use Tomcat's database pooling (which may eliminate the
need for 2)
. . . . just my two cents.

Re: deploy a war file
You can, although you'll have to reconfigure Tomcat in order to do this. However, it sounds like you want to place your war file where Apache httpd can see it (after enabling the mod_userdir and configuring it). If you do this and serve that directory with Apache httpd, some very unpleasant things will happen. kc8pdr/WEB-INF, and kc8pdr/META-INF will be visible. If you are using a Resource element in context.xml (stored in kc8pdr/META-INF), any information (like user names and passwords) will be visible to the world. Although you can prevent this by doing some more configuration work in Apache httpd, this requires extra steps. JSP pages will come across as text and code, not HTML. Servlets will come across as binary files, which users will be asked to download. Apache httpd does not run JSP, servlets, or any other Java-based technology. If you want to serve Tomcat applications via Apache httpd, you'll have to connect the two with mod_proxy_http, mod_proxy_ajp, or mod_ajp. To get an understanding on how to use mod_ajp, go here: http://tomcat.apache.org/connectors-doc/ Doing this passes requests for your Java web application from Apache httpd to Tomcat. Tomcat is doing all the work, and depending on your requirements (not stated), Apache httpd will e contributing little more than complexity. If you are only serving Java web applications, then you might just be better off not running Apache httpd and switching Tomcat to port 80.

Re: Configuring which Servlet is invoked
Chris, I'm going to leap into the middle of this discussion. Please feel free to discount what I'm going to say since I've just briefly glanced at the Roller 5.0 RC2 documentation. From what I understand, the intent is to have one Roller application running as the default web application (ROOT) on a Tomcat server, and have it be the default application for multiple blogger domains. From the Wiki page, Roller will handle multiple domains with one application by referring to a properties file, such as: # roller-custom.properties weblog.absoluteurl.photophys=http://photophys.com weblog.absoluteurl.alex=http://greenimp.me weblog.absoluteurl.linus=http://linusjohnson.com I'm guessing that somewhere in the Roller application these absolute URLs are mapped to internal URLs. Maybe this works like an internal mod_rewrite? I don't know, since I haven't looked at the code. Let's assume for a minute that Roller acts as if it has its own URL rewrite engine. If that's the case, then all Tomcat has to do is deliver the multiple URLs to the same application. In other words, photophys.com, greenimp.me, and linusjohnson.com should all be delivered to the ROOT web application of the default host, and Roller will figure out what to do from there. If that's the case, then what I think you need are aliases along with the default host definition. So using the above example, the following Host element can be constructed: Host name=localhost appBase=webapps unpackWARs=true autoDeploy=true xmlValidation=false xmlNamespaceAware=false Aliasphotophys.com/Alias Aliasgreenimp.me/Alias Aliaslinusjohnson.com/Alias /Host You'll have to set up all aliases to resolve to the same IP address that is your host. For testing, this can be done in the hosts file. In Linux it's /etc/hosts as long as your nsswitch.conf includes files for host resolution. In Windows/XP (don't know about other versions), it's in Windows\system32\drivers\etc. Hopefully Roller will do the correct thing internally. Fronting this with Apache httpd should not be too difficult if the above works. Basically, you'll use name-based virtual hosts with mod_jk (or mod_proxy_ajp) to map / and /* back to the same Tomcat server. Again, hopefully Roller will figure things out with the Alias elements. If I'm completely off base, please forgive the rambling. Again, I've not played with Roller (and this appears to be a release candidate), not looked at the source code, nor done more than skim one web page and the PDF docs. . . . just my two cents. /mde/ - Original Message From: Christopher Dodunski chrisfromsquir...@christopher.net.nz To: users@tomcat.apache.org Sent: Mon, October 11, 2010 9:20:48 PM Subject: Re: Configuring which Servlet is invoked Catalina logs contain some entries that may shine some light on the matter...

Re: Tomcat memory leak error launching web app in NetBeans 6.9.1
I saw a mention of this on the Quartz forums. People there seem to think it's a race condition between Quartz's scheduler shutdown and Tomcat's thread memory leak reporting. I wrote a quick Quartz scheduler (1.8.3) application. It does the following: 1. Uses the supplied listener to put a scheduler factory in the servlet context (org.quartz.ee.servlet.QuartzInitializerListener) 2. Uses another listener to add a job that writes to a log file every 5 minutes 3. Uses the provided listener (org.quartz.ee.servlet.QuartzInitializerListener) to shut down all schedulers The supplied listener is configured via parameters to start the scheduler on startup, and shut down the scheduler on application termination. When I watch this using visualvm (1.3.1) on Tomcat 6.0.18 and 6.0.29, I see the four threads that are started by Quartz vanish when the application is undeployed. Tomcat reports the SEVERE error for some of these threads in catalina.out. I ran the test twice and I think that Tomcat reported different threads on each run (didn't save the log files). I also didn't look for any stray classes left after the application was undeployed. The supplied listener can be configured to not start or shut down the scheduler. Starting and shutting down the scheduler can then be managed by the second listener (that adds the job). I've not tried this yet. Finally, there are two ways to shut down the scheduler.

That's what I've read and from the code it's the default. I'm hacking together a listener that rolls the entire chain from scratch rather than depending on the Quartz-supplied listener.

Re: Secondary instance of Tomcat on single server does not process requests
From the RUNNING.txt you will need tomcat-juli.jar in $CATALINA_BASE/bin. That being said, I start up and shut down 4 Tomcat instances when I'm working on cluster issues. Here's a typical directory structure I use for each Tomcat that's a part of the cluster: deimos-host/ ├── bin │ ├── setenv.sh │ ├── shutdown.sh │ ├── startup.sh │ └── tomcat-juli.jar ├── conf │ ├── Catalina │ │ └── localhost │ │ ├── host-manager.xml │ │ ├── manager.xml │ ├── catalina.policy │ ├── catalina.properties │ ├── context.xml │ ├── logging.properties │ ├── server.xml │ ├── tomcat-users.xml │ └── web.xml ├── lib ├── logs ├── temp ├── temp-dir ├── watch-dir ├── webapps │ ├── docs │ ├── manager │ ├── ROOT └── work I've left out the actual web applications and permissions. Here's my startup.sh script for the above host. #!/bin/bash export CATALINA_BASE=/someplace/deimos-host export CATALINA_HOME=/reference-place/apache-tomcat-6.0.29 $CATALINA_HOME/bin/startup.sh The shutdown.sh script is similar. I have a bunch of environment variables in setenv.sh. They reference where log4j logs should go and enables JMX. Those aren't really important. Finally, I start the entire cluster with the following script. #!/bin/bash ( phobos-host/bin/startup.sh ) sleep 5 ( deimos-host/bin/startup.sh ) sleep 5 ( mars-host/bin/startup.sh ) sleep 5 ( xerxes-host/bin/startup.sh ) The cluster shutdown script is similar. There are a few things to note in the above script. The parentheses are necessary around each startup script. If you take a look at the stock startup.sh script in $CATALINA_HOME/bin, you'll find that the last line is: exec $PRGDIR/$EXECUTABLE start $@ exec replaces the current shell. So if you write a script that tries to start multiple Tomcats, the first time you run the stock startup.sh script, your shell gets replaced. I have sleep statements in my script since this is for a cluster and I don't define a port in the Receiver element of the cluster.

Interesting. I'll have to try something similar for my situation. What I'm trying to do is a bit of the reverse.

In looking at the JSPs, the dev team is coding all the paths inside a c:url construct, which is why the context string is getting prepended to every path in the document. What was throwing me off a bit was the default doc was just a redirect as: -- %...@page contentType=text/html pageEncoding=UTF-8% % response.sendRedirect(login); % -- The browser would show this as http://hostname/context/login. My interpretation of the docs had me thinking that the context would get stripped as well, but it wasn't. Thus the confusion. I have managed to get it working with the following: Proxy balancer://mycluster BalancerMember ajp://prtltest01:8009/Portal route=tomcat1 loadfactor=50 BalancerMember ajp://prtltest02:8009/Portal route=tomcat2 loadfactor=50 /Proxy ProxyPass /Portal/static !

I'm trying to keep the Tomcat side of things fairly simple -- pretty much deploy the war direct from dev -- to keep there from being too many steps that could get screwed up when I'm not around and someone else needs to deploy. The process will be documented, but some people refuse to read directions correctly. Plus, the apache server will someday host multiple apps under one host, so having it work with the context as non-root now means less work later. Then again, I bf'ed and didn't put the static stuff in the proper tree structure under the htdocs dir. I just put them there as I got them.

Re: how to setup HOME_PATH for Java and CATALINA_HOME
From this and other messages, it looks like you're running everything installed from the Fedora distribution. While I run Fedora (just upgraded to Fedora 14), I don't use any of the distribution-supplied packages for Java, Tomcat, or the IDE (my preference being NetBeans). To get the Oracle / Sun Java installed, just download the appropriate files from Oracle. If you use the RPM packages, you can then use the alternatives program to switch between the various implementations. A detailed discussion on Fedora's Java implementation can be found here: http://fedoraproject.org/wiki/Java Then you will need to either inject Oracle's Java into the path before the Fedora-supplied Java or use the alternatives program to configure and switch between Java packages. The latter is more in line with the OS, while the former is what I currently do. Here's one link on how to use the alternatives program: http://www.if-not-true-then-false.com/2010/install-sun-oracle-java-jdk-jre-6-on-fedora-centos-red-hat-rhel/ I took a brief look at the Fedora-supplied Tomcat. As with many other distributions, the software is split across multiple packages, and contains extraneous material. If you're doing development, it's far easier to download a copy of Tomcat from tomcat.apache.org, unpack it somewhere handy, and then run it. I maintain multiple copies of Tomcat in ~/Apache along with various modifications to run Solr, Jetspeed, OpenPortal, Pluto, some virtual hosts, and some clusters. No, I don't run all of these at once. Your other problem is when you start using log4j in your application and want to build the war file. Normally when you add a server to NetBeans or (I presume) Eclipse, the IDE will use the server-supplied jar files to resolve references. The IDE will base which jars to pull from the server based on the type of server you've defined for a particular project. The problem is that Tomcat (as others have pointed out) does not come with log4j by default. If Eclipse is using the default definition of Tomcat, then a log4j jar file will not be included in the build path since the default installation does not have it. If you are set on running your application with Fedora's Tomcat distribution, then you will have to include log4j in your Eclipse project, but have it not added to the war file. If you are using a stock version of Tomcat, then you will have to add log4j to your project for both compilation and creation of the war. Since I don't normally use Eclipse, I have no real idea how to do this. My personal preferences are: 1. Install Java JRE/SDK/Docs from Oracle Either alter the path or use alternatives to manage multiple Java versions 2. Install Tomcat from ASF into my home directory for development 3. Install IDE of choice from that vendor. This makes getting help from the various mailing lists (Java, IDE, Tomcat) much easier. The only downside is that you will have to manage updates for these components manually. However, at least Java can be managed via yum (just download the RPM packages from Oracle). . . . . just my two cents /mde/ - Original Message From: Salam Y.

Tomcat will correctly infer the path 3. Place myapp.war in $CATALINA_BASE/webapps Tomcat (by default) will unpack and deploy your application 4. Remove the Manager node from your Context. The Manager node relates to managing HTTP Sessions. The Hibernate sessions relate to Hibernate units of work. 4a. Tomcat: http://tomcat.apache.org/tomcat-6.0-doc/config/manager.html 4b. Hibernate: http://community.jboss.org/wiki/sessionsandtransactions 5. Remove the Resource node from your Context. 6. Place the hibernate.cfg.xml file where it will be packaged in WEB-INF/classes. 6a. In a NetBeans project, place it in project-name/src/java 6b. In a Maven project, place it in project-name/src/main/resources 7. Use a ServletContextListener to get a Hibernate SessionFactory. Here's an example: http://community.jboss.org/wiki/UsingHibernatewithTomcat I do things a little differently, by creating a utility class, and then using that utility class in a listener.

The application even starts ok, I can see the logging of my classes. BUT! Each request to the application will throw immediately a HTTP error 400 - bad request. Funny enough, this error will not even be logged anywhere, even when I enabled debug logging in Tomcat! (and got 100M of logs which I searched through). No record of the 400 whatsoever, while I can confirm the Host header IS there - I see it in Firebug (and with the other context it works anyway). What I see different is that the Tomcat's work directory, the work/Catalina/localhost/com.mycomp.myapp directory it created automatically at startup is and stays EMPTY. Now normally there should be the compiled JSP's right? So there's SOMETHING not ok about this automatic deployment, and I'm unable to figure out what it is. There was in May an interesting discussion thread on this list called Misunderstanding deployOnStartup actions, but that guy also ended up using server.xml so...

Re: Modifying logging levels logged in catalina.out at runtime
Hopefully you're not creating custom logging levels. Creating custom logging levels is the classic way to create classloader leaks. See the following as an example: http://blogs.sun.com/fkieviet/entry/classloader_leaks_the_dreaded_java You can create a logging.properties file and place it in WEB-INF/classes. You can then change this file, rebuild your application, and redeploy it without taking down Tomcat. You could also add a WatchedResource element to your Context and point it at WEB-INF/classes/logging.properties. When that file is changed, Tomcat will reload the application. See: http://tomcat.apache.org/tomcat-5.5-doc/config/context.html I'm not really sure you want to do the WatchedResource configuration in a production environment though . . . . . . . just my two cents. /mde/ - Original Message From: Jason Pyeron jpye...@pdinc.us To: Tomcat Users List users@tomcat.apache.org Sent: Wed, December 1, 2010 11:59:28 AM Subject: Modifying logging levels logged in catalina.out at runtime This may be slightly off-topic.

Re: Place .ini conf file inside the war package.
Read about using properties files. They're typically called name.properties.
Snippet of code that can be placed in a ServletContextListener.
String resource = some.properties;
InputStream in = this.getClass().getClassLoader().getResourceAsStream(resource);
try {
props.load(in);
in.close();
} catch (IOException ex) {
ex.printStackTrace(); // ugly
}
Note that this is not a complete ServletContextListener. Normally I create a
separate class, have that class's constructor read the properties file, and
then
use the ServletContextListener to create a servlet context attribute with the
information.
You can use an init parameter to read the resource name from web.xml, and then
pass that information to your class as an argument to the constructor. Catch
exceptions (such as file not found) appropriately.
The Apache commons configuration (mentioned in another message) provides a lot
of nice tools for reading properties files.
Place the some.properties file in src/main/resources of your Maven project.
This
will get it packed up in WEB-INF/classes of your war file once you run maven
package.
Read the javadoc on Class.getResourceAsStream() concerning how to locate the
properties file.

Re: deploy log4j
You don't say the following:
Tomcat version
JRE/JDK version
Platform (OS and version)
That being said, I use log4j (with or without Apache commons logging) for
nearly
every web application I run on Tomcat.
Short answer: You don't manually read in your properties file with log4j.
Read a tutorial on log4j for a more complete explanation.
What follows below is an overview. Please refer to the log4j documentation, the
log4j javadocs, and tutorials around the Internet for a more complete
discussion.
Code:
In each class that you want to use logging, add the following:
package foo; // replace with your package name
import org.apache.log4j.Logger;
public class MyFoo { // replace with your class name
private static final Logger log = Logger.getLogger(MyFoo.class); // note 1
/*
* rest of class including log.(message) where is a level
*/
}
note 1: While it is traditional that one uses getLogger(MyFoo.class), which is
shorthand for getLogger(clazz.getName()), you can also name your loggers with
any legal string. See the javadoc for more information.
Properties File:
In your properties file, you'll need appenders as well individual lines for
non-default logging levels for each logger name.
### direct messages to file foo.log ###
log4j.appender.file=org.apache.log4j.FileAppender
log4j.appender.file.File=${catalina.home}/logs/foo.log
log4j.appender.file.layout=org.apache.log4j.PatternLayout
log4j.appender.file.layout.ConversionPattern=%d{ABSOLUTE} %5p %c{1}:%L - %m%n
# default logging level
log4j.rootLogger=warn, file
# logging for foo.MyFoo - name matches the logger name
log4j.logger.foo.MyFoo.type=info
Since there is only a file listed in the appenders, then that's where the
logging will go.
Note that ${catalina.home} was used for logging. This should probably
be ${catalina.base} just in case more than one copy of Tomcat is run from a
base
installation (see RUNNING.txt). This is a handy way of storing log files.
If you're doing some in-IDE testing where ${catalina.home} or ${catalina.base}
is not set, then hopefully your IDE will let you pass in a Java parameter. Just
set
-Dcatalina.home=some-place (or -Dcatalina.base=some-place) while testing.
Application Structure:
Properties file
Package up the application so that log4j.properties gets placed in
WEB-INF/classes/log4j.properties. Log4j looks for the properties file in the
classpath. Placement in your IDE's project depends on how your IDE packages
files.
Log4j library
Package up the application so that log4j-1.2.15.jar (or whatever version you
are
using) gets placed in WEB-INF/lib/log4j-1.2.15.jar. Placement in your IDE's
project depends on how your IDE packages files.
. . . . just my two cents.

HTTP status 404 description the requested resource (/filename/)is not available Hi. Except the 404 error which your are getting, not much above makes any sense at all. So it is better to forget all that, and start new. You really have to learn to walk before you can run. First, consider the directory structure of a standard Tomcat installation : (CATALINA_HOME) (=CATALINA_BASE) | |- bin (tomcat programs and scripts) |- conf (configuration files) |- lib (global library files) |- logs (logfiles) |- webapps (* web applications *) |- ROOT (the special, top-level, default web application) |- app1 (a web application) |- app2 (another web application) |- ... |- lastapp (another web application) In the above, (CATALINA_HOME) represents the top directory of your Tomcat installation, the one under which the rest of Tomcat is found. For example, on your system it may be C:\tomcat or C:\program files\Apache Software Foundation\tomcat6.0 or /usr/share/tomcat6 or /usr/local/tomcat6 or whatever. The webapps sub-directory is what is important for you now. That is where you will put web applications, composed of static html pages (with or without javascript in them), JSP pages (special html pages with embedded Java code), java servlets (compiled java applications), etc.. The ROOT web application is special. It is the default application. When you use a URL like : http://yourserver.yourcompany.com/abc.html Tomcat is going to look for abc.html under the webapps/ROOT directory. The other subdirectories under webapps are each one separate web application. To access for example the application named app1, you will have to use a URL starting with http://yourserver.yourcompany.com/app1/; For example, if you place a html page named xyz.html in the subdirectory (CATALINA_HOME)/webapps/app1, then the URL to call it up will be http://yourserver.yourcompany.com/app1/xyz.html Under such a web application directory like ../webapps/app1, there is also a structure. It looks like this : (CATALINA_HOME) (=CATALINA_BASE) |- webapps (* dir, top of all web applications *) | |- app1 (dir, contains the web application named app1) - public files (html etc..) - WEB-INF (directory) |- files (private) |- web.xml (configuration file

Re: deploy log4j
cpannon,
I just wrote a very simple web application (2 JSP files, one servlet) and added
log4j. I ran this on Linux and Windows/XP with both console and file logging. I
don't have access to a Windows server platform (all UNIX or Linux) so I cannot
test there. Note, I'm not running under a security manager, and on Windows/XP
I'm running with an account that has administrator privileges (I know, I know).
However, Tomcat is started using the local System account, so its privileges
are
more limited.
I didn't get any errors.
A portion of the log4j.properties file:
### direct log messages to stdout ###
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.Target=System.out
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d{ABSOLUTE} %5p %c{1}:%L - %m%n
The above generates log messages to catalina.out on Linux and stdout_date.log
(in %CATALINA_HOME%\logs) on Windows/XP.
As Chris has pointed out, be careful where you put your log4j jar file. Since
you're logging for a particular web application, place the log4j jar file in
Application/WEB-INF/lib.
I'm not sure what potential classloader issues you will run into if you place
the log4j jar file in $CATALINA_HOME/lib. Definitely do not place the jar file
in both $CATALINA_HOME/lib and Application/WEB-INF/lib.
. . . . just my two cents.

This is the where the differences in the platforms affects the results with

1. On Windows2K Server and Windows2003 Server it fails to find the properly

2. On WinXPP it works perfectly under production TC 6.0.29, finding the

You should probably not be using Class.getResourceAsStream, but instead
ServletContext.getResourceAsStream. The latter will always load
resources relative to the webapp instead of potentially randomly for
whatever ClassLoader you happen to stumble across.
Where is the code you originally posted running? In a
ServletContextListener? Where is the class for that listener located?
If you are playing games with .jar files and/or classes in the wrong
place because you want to save disk space or something like that, you
will end up with these weird kinds of errors, and you will probably end
up with enormous memory leaks if you (hot) redeploy your webapp.

Re: HTTP status 404
Lava, I changed the index.htm to filename.htm then I navigated to localhost:8080/filename and it didn't work , I also copied the filename.war file to the webapps and nothing changed Odd, when I do this and type localhost:8080/Static, I get a 302 and redirected to localhost:8080/Static/ automatically. Then my welcome page (index.html) gets displayed. Hmm, as an aside maybe a 307 is more appropriate (but pre-HTTP 1.1 clients may not understand this, and who knows what IE does)? What is your complete web.xml? the filename pops up, on the manager side its says running but the session stays zero You don't get sessions for free. Sessions are different than connections. I don't know your background, but it sounds like some reading is in order. A book that seems to be helpful is Headfirst Servlets JSP. The second edition covers the servlet 2.5 specifications. You'll need to have a basic understanding of Java in order to use this book, but it does a good job of explaining a lot of material. The exercises are reasonable as well. . . . . just my two cents. /mde/ - Original Message From: Lava Saleem lnsal...@ualr.edu To: users users@tomcat.apache.org Sent: Thu, December 9, 2010 11:40:14 AM Subject: Re: HTTP status 404 Hi Mark, I have changed my web.xml file to the one you send me and added the welcome-file-list so I will not need to navigate to localhost:8080/filename/filename.htm, I changed the index.htm to filename.htmthen I navigated to localhost:8080/filename and it didn't work , I also copied the filename.war file to the webapps and nothing changed however after changing the web.xml file when I navigate to localhost:8080/filename/filename.htm the filename pops up, on the manager side its says running but the session stays zero so to be honest I'm kinda confuse is it working now ?if I changed the web.xml shouldn't be working on localhost:8080/filename/ ?

Change to the directory filename 2. jar cf ../filename.war . 3. cd .. 4. jar tf filename.war (should give you the complete structure) One way to use the war file: 1. Copy filename.war to $CATALINA_HOME/webapps If running, the default configuration of Tomcat will explode the war file and you will see a filename directory in $CATALINA_HOME/webapps along with filename.war.

Re: deploy log4j
Quick question: Are you running under a security manager in any environment? The logs (most likely catalina.out or catalina.date.log) will have lots of messages if you've not modified the default $CATALINA_HOME/conf/catalina.policy file. For example, if I run my simple application that has its first logging instance in a servlet under the security manager using the default catalina.policy, I get as the first line of the error: javax.servlet.ServletException: Error instantiating servlet class simple.controller.SimpleLog If you are doing your first logging in a ServletContextListener, your application will likely not start at all. The configuration can get complicated quickly. There should be a policy that allows the appropriate log4j class to read its configuration file. There should be another policy that allows the appropriate log4j class to read/write in the log directory as well as the appropriate log files. Maybe someone on the list has already written the appropriate catalina.policy lines. If you're not running using the security manager, then please disregard the noise. . . . . just my two cents. /mde/ - Original Message From: cpanon cpa...@yahoo.com To: Tomcat Users List users@tomcat.apache.org Sent: Thu, December 9, 2010 6:43:39 PM Subject: Re: deploy log4j Hello I agree it should be simple and in the IDE it works fine.
