Shutting down one instance of tomcat 6 from a listener
Hello, I'm working with tomcat 6 and multiples instances; I'm looking for a solution to stop an instance of Tomcat from a listener. The purpose of this listener is to load and check some configurations files such as Spring configuration. Then, if an error is found, to stop this instance. On a Tomcat with only one instance I was using System.exit(1), this solution isn't good of course with multiples instances. What would be the best solution?

setenv.sh in an individual tomcat catalina base
Hi guys, At the moment i have several catalina bases configured with the following directories, conf logs server webapps work The bin, lib and common directories are all still in $CATALINA_HOME. I now need to add a setenv.sh file in the bin directory but i dont want it to be used by all the catalina bases. I only want 2 out of the 4 catalina bases to use the setenv.sh file. To do this i am thinking of adding a bin directory on the catalina_base/bin that i want to pick up the setenv.sh file. The bin directory will only contain the setenv.sh file and nothing else. Everything else will still be in $CATALINA_HOME/bin/ (ie. startup.sh catalina.sh shutdown.sh etc). This means that some catalina bases will have /bin directories and some wont. Are there any side effects to doing this? Can tomcat use both $CATALINA_BASE/bin/ and $CATALINA_HOME/bin during startup?

HTTP request and responses mixed up
Hi all, We are currently experiencing an issue on our system where user A gets the HTTP response intended for user B. In fact, user A and user B are two completely different users that are logged on to our system. User A and User B both a send a different request and then BOTH users get the same response. This problem occurs sporadically and so far we have not been to reproduce it. Our setup is as follows: We have a server that runs apache and acts as a reverse proxy to the second apache on another server. Both these servers run Apache 2.2.9. The apache on the second server includes the mod_jk module and this server also runs a tomcat which routes the requests to our backend java application. Detail specification of the problem scenario: In the web GUI, user A requests a list of customers and user B requests a list of the current orders (these requests are be handled in different servlets). User A receives the correct list of its customers, however User B gets the same HTTP response! We traced both requests through the entire chain of apache/apache/tomcat/backend etc. and we see both requests (User A and User B) in the logging of our first and second apache. These requests are for completely different servlets, this rules out any coding problems inside the servlet. The reason why we can correlate the HTTP response of User A with the HTTP response User B receives, is the size of the HTTP response in the apache logging. We have looked through the change log of tomcat/apache and we have searched many forums to see if others have encountered this issue. Unfortunately, we have found very little information. It is also very difficult to reproduce this situation, since it occurs randomly and we have only seen it happen 3 times in about 2 months time. System specification: OS: Solaris 10 Apache: 2.2.9 Tomcat: 6.0.16.0 Tomcat_jvm: 1.6.0_07-b06 mod_jk: 1.2.26 java: 1.6.07 The versions of apache/tomcat etc. have not been updated for quite some time (more than a year at least). If anyone could shed some light on this issue or has experienced it themselves: any information would be greatly appreciated.

[OT] Jconsole Perform GC?
Anyone know what exactly what kind of GC the Perform GC button in Jconsole does? I had a Tomcat instance that I'd been monitoring since yesterday morning, because the end users were getting some interesting OOM errors. The initial work was mostly in the Eden space and Survivor spaces for most of the day, then suddenly, a big chunk (nearly 4GB) ended up in the Old Gen space and pretty much stayed there all night. During that time, the Survivor space was mostly flat, with the Eden space showing slow constant growth (45 degree angle) with period resets to near zero. So I came in this morning, and saw this pattern, and knowing that the customer was not using the system yet, pressed the Perform GC button and was surprised that the memory usage dropped to near zero. Reviewing the individual graphs showed that the bulk of the retrieved memory was from the Old Gen space. It had been consistently flat at close to 4.0 Gb since about 4:00 pm until I did the GC, which dropped it to near zero use. Looking at the other individual graphs showed that there had been several instances of GC performed by the JVM during that time, but it took my manual instance to clear the Old Gen. Is this just normal JVM GC processing? Does it not gc a Gen unless it is nearly full? It's been awhile since I read the Sun docs on the subject, so it might be something in the way Java 6 is architected.

Re: setenv.sh in an individual tomcat catalina base
Hi. As I recall, you are using a packaged version of Tomcat (meaning not the original one from the tomcat website download, but one already packaged by the people who do such things for your OS version). You should then look carefully at what scripts are used to start/stop Tomcat on your particular system (starting with /etc/init.d/tomcat e.g.), what they invoke and when, to determine what you can put into CATALINA_HOME/x and CATALINA_BASE/y. For example, these packages often use a file /etc/default/tomcat that sets some environment values, which are later used to determine what other scripts do. What Konstantin indicates below is based on the standard catalina.sh as provided in the standard Tomcat download, but there is no guarantee that this script has not been modified (or is even used) in your particular package.

Single webapp multiple contexts
Hello Tomcat Users, I am trying to create multiple 'dynamic' contexts using just a single code base. For example we currently deploy a webapps within a context of let's say 'A'. This listens quite happily for requests coming in the form of http://localhost/A/index.htm. What I need to be able to do is have this same code base also listen for requests in the form of http://localhost/B/index.htm. I have played with using 'fake' context.xml e.g. A.xml = Context useHttpOnly=true docBase=C:/0600/ieseries.war path=/A / B.xml = Context useHttpOnly=true docBase=C:/0600/ieseries.war path=/B / This seems to work but the war is expanded into both contexts and what I really need is a single code base preferably without the requirement of using a .war file. I have looked at virtual hosts but this seems to involve changing the host name which is also not what I am trying to achieve. Using Tomcat 6.0.29 under Java(TM) SE Runtime Environment (build 1.6.0_14-b08). CATALINA_HOME is C:/0600. Can anyone give me a gentle push in the right direction if this is at all possible. Thanks in advance. Rob

Subject: Single webapp multiple contexts
Hello Tomcat Users,
I am trying to create multiple 'dynamic' contexts using just a single
code base. For example we currently deploy a webapps within a context
of
let's say 'A'. This listens quite happily for requests coming in the
form of http://localhost/A/index.htm. What I need to be able to do is
have this same code base also listen for requests in the form of
http://localhost/B/index.htm. I have played with using 'fake'
context.xml e.g.
A.xml = Context useHttpOnly=true docBase=C:/0600/ieseries.war
path=/A /
B.xml = Context useHttpOnly=true docBase=C:/0600/ieseries.war
path=/B /
This seems to work but the war is expanded into both contexts and what
I
really need is a single code base preferably without the requirement
of
using a .war file. I have looked at virtual hosts but this seems to
involve changing the host name which is also not what I am trying to
achieve.
Using Tomcat 6.0.29 under Java(TM) SE Runtime Environment (build
1.6.0_14-b08). CATALINA_HOME is C:/0600.
Can anyone give me a gentle push in the right direction if this is at
all possible.
Thanks in advance.
Rob

Hi Andre, I am using a standard Tomcat installation downloaded from tomcat.apache.org.

As I recall, you are using a packaged version of Tomcat (meaning not the original one from the tomcat website download, but one already packaged by the people who do such things for your OS version). You should then look carefully at what scripts are used to start/stop Tomcat on your particular system (starting with /etc/init.d/tomcat e.g.), what they invoke and when, to determine what you can put into CATALINA_HOME/x and CATALINA_BASE/y. For example, these packages often use a file /etc/default/tomcat that sets some environment values, which are later used to determine what other scripts do. What Konstantin indicates below is based on the standard catalina.sh as provided in the standard Tomcat download, but there is no guarantee that this script has not been modified (or is even used) in your particular package.

Tomcat log files
I'm trying to clean up Tomcat logging to use log4j. I've read the Tomcat logging guide that comes with my version of Tomcat 6.0.28. I'm really confused with all the different log files that are being generated in the default Tomcat before log4j configuration. Why are there so many different log files: admin, manager, localhost, manager, host-manager, catalina log files and then System.out and System.err get appended to catalina.out? What's the purpose of each of these log files? When I configure log4j in tomcat I will have this single tomcat.log file but will that contain everything in the default log files that I previously listed in addition to catalina.out? Or will I need to use both tomcat.log and catalina.out to get a full picture of all of my logging? I tried to delete the logging.properties file in my Tomcat 6.0.28 and I get a NoClassDefFoundException in doing so.

Backend Cookie Validation
Hi all, A little stumped on how to accomplish this: I am trying to have a cookie validated in Tomcat against a mysql entry, if it validates it should proceed to the requested resource, and if not, it should redirect to a different page (which writes the cookie on successful login). The idea is to have tomcat somehow capture the http request, check for the cookie presence, capture the cookie contents and compare them against the db (I already have this), and proceed with the request if everything checks out, or redirect to a login page (which is outside of the tomcat app, I think it is running on rails). Any ideas on how to do this? Much appreciated! - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

Re: Tomcat log files
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Timothy, On 11/9/2010 1:48 PM, Timothy Lam wrote: I'm trying to clean up Tomcat logging to use log4j. I've read the Tomcat logging guide that comes with my version of Tomcat 6.0.28. Excellent. I'm really confused with all the different log files that are being generated in the default Tomcat before log4j configuration. Why are there so many different log files: admin, manager, localhost, manager, host-manager, catalina log files and then System.out and System.err get appended to catalina.out? What's the purpose of each of these log files? So, the log files for admin, manager, and host-manager are application-specific log files. Anything the application sends to ServletContext.log() will go to these files. The localhost log is for anything emitted by the Host name=localhost and catalina.out is exclusively for stdout and stderr, and is done via shell redirection (so you shouldn't see any configuration for it anywhere other than bin/catalina.sh). All of these are configured in conf/logging.properties, though they may not have a ton of explanation as to /why/ they are configured the way they are. You are free to change any of this configuration -- for instance, to remove the manager, host-manager, and admin log files. I would recommend not deploying any unused webapps, and enabling logging for any webapps you actually do use. When I configure log4j in tomcat I will have this single tomcat.log file but will that contain everything in the default log files that I previously listed in addition to catalina.out? It should. - From the docs: You can (and should) be more picky about which packages to include in the logging. Tomcat defines loggers by Engine and Host names. For example, for a more detailed Catalina localhost log, add this to the end of the log4j.properties above. Note that there are known issues with using this naming convention (with square brackets) in log4j XML based configuration files, so we recommend you use a properties file as described until a future version of log4j allows this convention. log4j.logger.org.apache.catalina.core.ContainerBase.[Catalina].[localhost]=DEBUG log4j.logger.org.apache.catalina.core=DEBUG log4j.logger.org.apache.catalina.session=DEBUG If you read a bit more about log4j (not covered by the Tomcat docs, of course), you'll find that you can set up logging for different applications by using different appenders like this: log4j.appender.LOCALHOST=org.apache.log4j.FileAppender log4j.logger.org.apache.catalina.core.ContainerBase.[Catalina].[localhost]=LOCALHOST If you repeat this for each of the default loggers defined for the JULI configuration (which you are replacing with log4j), you'll get the same setup. I'm not sure why the documentation doesn't show an equivalent configuration for log4j. Maybe I'll write one and submit it for inclusion. Or will I need to use both tomcat.log and catalina.out to get a full picture of all of my logging? catalina.out will always include whatever goes to stdout/stderr: the use of log4j won't change that. I tried to delete the logging.properties file in my Tomcat 6.0.28 and I get a NoClassDefFoundException in doing so. logging.properties isn't supposed to be necessary, but I seem to recall some issue with the shell scripts choking when logging wasn't completely configured correctly. Have you correctly replaced lib/tomcat-juli.jar and installed lib/tomcat-juli-adapters.jar? If not, you may be falling back to the old logger which requires logging.properties. So there doesn't seem to be any way of really removing java.util.logging from Tomcat in v6.0.28. Yes, it can be done.

User A receives the correct list of its customers, however User B gets the same HTTP response! Have you received reports directly from your users, then? We traced both requests through the entire chain of apache/apache/tomcat/backend etc. and we see both requests (User A and User B) in the logging of our first and second apache. These requests are for completely different servlets, this rules out any coding problems inside the servlet. The reason why we can correlate the HTTP response of User A with the HTTP response User B receives, is the size of the HTTP response in the apache logging.

Re: DBCP abandoned trace - unable to understand the leak
After changing time out value now I am getting this problem org.apache.tomcat.dbcp.dbcp.SQLNestedException: Cannot get a connection, pool error Timeout waiting for idle object On Tue, Nov 9, 2010 at 5:22 PM, Christopher Schultz ch...@christopherschultz.net wrote: -BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Sasidhar, On 11/8/2010 12:31 AM, sasidhar prabhakar wrote: On Thu, Nov 4, 2010 at 9:10 PM, Christopher Schultz ch...@christopherschultz.net wrote: I have found that these exceptions can occur even when there is no leak. Specifically, if your SQL query takes a long time to run (that is, more than the ababdonedTimeout), another request to the connection pool complains about the connection and calls it abandoned. I think your right. Timeout I mentioned 30sec deafault is 300sec. This is my context.xml ?xml version=1.0 encoding=UTF-8? Context path= path is not allowed in context.xml: remove it. validationQuery=SELECT * from dual SELECT *? Wow. How about SELECT 1 FROM dual? testOnBorrow=true removeAbandoned=true removeAbandonedTimeout=30 That's a 30-second abandoned timeout. username=scott password=*** tiger, right? Technically speaking, the connection hasn't been leaked, but the connection pool can't really guess the reason why the connection hasn't been returned. Can you time your queries to see how long they take? Could you post your Resource configuration for your DataSource? For some queries it took more than 30 seconds, from getting data from ip_to_geo table, which has 3 million rows in it. That could be your problem: you should probably increase your removeAbandonedTimeout value to something more appropriate for your application. You might also want a dba to check out your queries and your database structure. 3 million rows isn't that much, even for Oracle :) Another note: I notice that you are using a DataSource object that survives for the life of the DAO object, and is even created by the object in its constructor. Every DAO has only one instance for the entire life of application. Is this correct approach. So Every thread accessing the same datasource object to get connection. It was just a recommendation which gives you flexibility: your webapp (or the container, etc.) has the freedom to discard and completely re-build the DataSource for your webapp if you always go to the JNDI context to get the DataSource. Otherwise, you will force a webapp restart just to get a new DataSource. - -chris -BEGIN PGP SIGNATURE- Version: GnuPG v1.4.10 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAkzZ180ACgkQ9CaO5/Lv0PDicACfZ/rv+FN8cT8JATK2ZlGYgWUW CPoAn2/j0NO6af4RuL9t7j4yH9wXP+bW =l181 -END PGP SIGNATURE- - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
