tomcat thru netbeans 3.6
I've got this problem and I'm not sure how to solve it. I'm hoping someone can steer me the right way. My problem is that I have my static files for the webapp located right off of the webapps directory like this. $tomcat/webapps/myapps $tomcat/webapps/myapps/images Now on my production server I use jk and apache and I was able to JkMount / myapps/* ajp13 and this allowed by webapp to see the images directory and the other static include files it works correctly. BUT on my development machine (I'm switching from a win98 to a linux) Anyway I'm using Netbeans 3.6 and the builtin tomcat server that it comes with (5.0.19) I setup my complier for external and netbeans places all the classes in the correct way, I can compile the entire app. But when I run tomcat I can run my app but the references to the images, my include scripts.js, don't load. Can someone help me with where in either tomcat's server.xml, web.xml or with the apps web.xml that I place the correct config info so that tomcat allows the app access to these directories.

if i understand the question right i have a few suggestions:
-if ur using unixes u can just symlink via ln -s /newdir /oldir.
-or, on the old dir you can change the index.jsp to redirect to the
new dir via meta refresh or forward or include.

Re: Pass info between Tomcat Valve and Filter
An invocation of a Tomcat Valve gives you a Request object. This is a facade to a ServletRequest, which you can access via the getRequest() method. You could set your info object as an attribute on the ServletRequest. This should then be visible to your filter. http://jakarta.apache.org/tomcat/tomcat-4.1-doc/catalina/docs/api/index.html Just curious, why the custom Valve?

Re: webdav servlet problems with Tomcat 5.0.24 and IE
Mark, First of all it is worth pointing out that this works quite happily for me on WinXP using TC5.0.24 and IE6. Ah, the wonderful world of M$. There are difference between how tomcat 4 and 5 handle redirection from www.yourhost.com/webdav to www.yourhost.com/webdav/ Either should be valid but the webdav implementation in IE doesn't handle http redirection responses correctly. This is why TC4 works with / but TC5 sometimes has trouble with IE clients. Needless to say when I tried to report this to Microsoft they refused to acknowledge this as a bug and said I needed to pay to get any further support. Do you know how the TC4 handles the redirection issue? We have a webapp to which we are adding webdav support. Our webdav implementation has exactly the same problem as the TC5 implementation when using IE clients. If we set the url-pattern to /* we break our webapp. A few other thoughts: - does it work if you run TC5 on a windows box? Have not tried this. I'll install on one of our boxes and test. - are you using the webdav servlet as it comes with TC5? We are.

Re: running Tomcat from jsvc daemon under Linux as user tomcat
I have set everything in the entire $CATALINA_HOME directory tree to be owned by user tomcat, group tomcat. I even tried setting them to user.root and put tomcat in the root group. Still, Tomcat cannot write to the work dir. When I try to run jsvc as user root, I get a java.lang.reflect.InvocationTargetException. But when I run as root using startup.sh, everything's fine. And once I've compiled the jsps in the work directory and the class files exist, then I can run them under the daemon. So there's definitely something fishy with the jsvc daemon that is preventing me from compiling. I carefully set up the init.d tomcat script so that it mimics startup.sh as much as possible. Still no dice. I've turned on debugging and I see that when the daemon kicks off, it lists its parsed command line arguments (I've posted the output below). There are options such as run as service, install service, etc. Should I be trying to run as service? ..Bob. catalina_home is /usr/local/tomcat5 setting classpath classpath is @/usr/lib/java/lib/tools.jar:/usr/local/tomcat5/bin/commons-daemon.jar:/usr/local/tomcat5/bin/commons-logging-api.jar:/usr/local/tomcat5/bin/bootstrap.jar@ jsvc debug: +-- DUMPING PARSED COMMAND LINE ARGUMENTS -- jsvc debug: | Detach: True jsvc debug: | Show Version:No jsvc debug: | Show Help: No jsvc debug: | Check Only: Disabled jsvc debug: | Run as service: No jsvc debug: | Install service: No jsvc debug: | Remove service: No jsvc debug: | JVM Name:server jsvc debug: | Java Home: /usr/lib/java jsvc debug: | PID File:/usr/local/tomcat5/logs/catalina.pid jsvc debug: | User Name: tomcat jsvc debug: | Extra Options: 8 jsvc debug: | -verbose jsvc debug: | -Dcatalina.home=/usr/local/tomcat5 jsvc debug: | -Djava.io.tmpdir=/usr/local/tomcat5/temp jsvc debug: | -Djava.endorsed.dirs=/usr/local/tomcat5/common/endorsed jsvc debug: | -Dcatalina.base=/usr/local/tomcat5 jsvc debug: | -Djava.class.path=/usr/lib/java/lib/tools.jar:/usr/local/tomcat5/bin/commons-daemon.jar:/usr/local/tomcat5/bin/commons-logging-api.jar:/usr/local/tomcat5/bin/bootstrap.jar jsvc debug: | -Xms256m jsvc debug: | -Xmx384m jsvc debug: | Class Invoked: org.apache.catalina.startup.Bootstrap jsvc debug: | Class Arguments: 0 jsvc debug: +--- jsvc debug: user changed to 'tomcat' jsvc debug: User 'tomcat' validated jsvc debug: Attempting to locate Java Home in /usr/lib/java jsvc debug: Attempting to locate VM configuration file /usr/lib/java/jre/lib/jvm.cfg jsvc debug: Found VM configuration file at /usr/lib/java/jre/lib/jvm.cfg jsvc debug: Found VM client definition in configuration jsvc debug: Checking library /usr/lib/java/jre/lib/i386/client/libjvm.so jsvc debug: Found VM server definition in configuration jsvc debug: Checking library /usr/lib/java/jre/lib/i386/server/libjvm.so jsvc debug: Found VM hotspot definition in configuration jsvc debug: Checking library /usr/lib/java/jre/lib/i386/hotspot/libjvm.so jsvc debug: Checking library /usr/lib/java/lib/i386/hotspot/libjvm.so jsvc debug: Cannot locate library for VM hotspot (skipping) jsvc debug: Found VM classic definition in configuration jsvc debug: Checking library /usr/lib/java/jre/lib/i386/classic/libjvm.so jsvc debug: Checking library /usr/lib/java/lib/i386/classic/libjvm.so jsvc debug: Cannot locate library for VM classic (skipping) jsvc debug: Found VM native definition in configuration jsvc debug: Checking library /usr/lib/java/jre/lib/i386/native/libjvm.so jsvc debug: Checking library /usr/lib/java/lib/i386/native/libjvm.so jsvc debug: Cannot locate library for VM native (skipping) jsvc debug: Found VM green definition in configuration jsvc debug: Checking library /usr/lib/java/jre/lib/i386/green/libjvm.so jsvc debug: Checking library /usr/lib/java/lib/i386/green/libjvm.so jsvc debug: Cannot locate library for VM green (skipping) jsvc debug: Java Home located in /usr/lib/java jsvc debug: +-- DUMPING JAVA HOME STRUCTURE jsvc debug: | Java Home: /usr/lib/java jsvc debug: | Java VM Config.: /usr/lib/java/jre/lib/jvm.cfg jsvc debug: | Found JVMs: 2 jsvc debug: | JVM Name:client jsvc debug: | /usr/lib/java/jre/lib/i386/client/libjvm.so jsvc debug: | JVM Name:server jsvc debug: | /usr/lib/java/jre/lib/i386/server/libjvm.so jsvc debug: +--- jsvc debug: Using specific JVM in /usr/lib/java/jre/lib/i386/server/libjvm.so jsvc debug: Invoking w/ LD_LIBRARY_PATH=/usr/lib/java/jre/lib/i386/server:/usr/lib/java/jre/lib/i386 jsvc.exec debug: +-- DUMPING PARSED COMMAND LINE ARGUMENTS -- jsvc.exec debug: | Detach: True jsvc.exec debug: | Show Version:No jsvc.exec debug: | Show Help: No jsvc.exec debug: | Check Only: Disabled jsvc.exec debug: | Run as service: No jsvc.exec debug:

Re: The tomcat not accept more connections
Ok, I don't know about timings - that is an entirely different question. Tomcat is not accepting connections because you've run out of processors to create them (defined in server.xml - this example is for my SQL connection): !-- Define an AJP 1.3 Connector on port 8009 -- Connector className=org.apache.ajp.tomcat4.Ajp13Connector port=8009 minProcessors=3 maxProcessors=15 acceptCount=10 debug=0/ If you are running out of processors it is because you are creating connections and then not closing them after use, it is important that you do this. If you are connecting to a database then when you creat a new connection eg. Connection conn = dbClass.getConnection() you must close that connection when you have finished interrogating the DB. IN this case you would use conn.close(); HTH. Adam On Thu, 2004-05-20 at 20:25, Software wrote: OK but is that the reasos that the tomcat not accept more connections?

Upon application shutdown, non-serializable attributes will be removed so that upon restart, the non-serializable attributes won't exist in the session. Not sure if that is your problem here, but it's a good thing to note. http://archive.apache.org/dist/jakarta/tomcat-5/v5.0.25-alpha/ Jake Well, yes and no. That is, on the remote server it is 5.0.19 but locally on my laptop (Win2K) and on a Linux box (FC1) I downloaded and installed 5.0.24. I wrote a pair of simple test jsp's and the version on the Win2K machine certainly has problems as the session is different on every submit. The remote server and the Linux box seem better. After reading your note I uninstalled the 5.0.24 version then downloaded and installed the 5.0.25-alpha version (the alpha part scared me which is why I went with the 5.0.24 before). Interestingly enough it also seems to exhibit the same behaviour (new session on every submit).

Re: Session Timeout and Direct Reference to login page

Yeah, that seems like it would work. I'm wondering if I could maybe use a

1. Intercept all requests with a filter.
2. Get the HttpSession out of the request. Get the session ID by calling
HttpSession.getId();
3. Get the cookie array and see if there is a cookie named jsessionid. If
there is, compare the two session IDs. If they are different forward to
sessionexpired.jsp to display error page. Otherwise, continue as normal.

RE: equivalent of DefaultContext element for Host
Hi, The spirit of the servlet specification calls for every webapp to be self-contained and portable. Using DefaultContext by definition means your webapp depends on server-global settings. It's a subtle but significant difference from it depending just on its own server configuration (in this case its own Context element or its equivalent in other servers). This is not the end of the world as far as portability or self-containment goes, and if this is your worst design mistake then you're in great shape, but nonetheless try not to overuse it. And of course your point about having many hosts mitigates your choice.

RE: Memory leak with Tomcat 5.0.19
I added the request.registerRequests=false to jk2.properties yesterday, but I still do not have a definite confirmation on whether this problem is fixed. The JVM did grow to over 600MB, which is more that my Tomcat 4.1.x instances, but Tomcat crashed the site yesterday at about 7pm, so I didn't have a chance to see if the memory continued to grow. (there was about 200MB free of the 624 MB allocated at the time of the crash - I'll have to deal with that later). I read the documentation on jk2.properties, but didn't really get much there. Is there anyone with a good documented jk2.properties files that would care to share? BTW - for all interested, I also set development to false, and fork to true in web.xml. I have also removed jsvc from the equation just to make sure it is not part of the problem.

Also note that Tomcat-5.0.24+ is very strict about objects in the session being serializable (where 5.0.19 was less so).

Tomcat 5: Location of 3rd party JNDI datasource jars in $CATALINA _HOME/common/lib
Hi all, This probably a simple question but I cannot find any answer to this in the FAQ or buglist. Why is it that the required jars for 3rd party JNDI datasource (such as JDBC pools) have to be placed in $CATALINA_HOME/common/lib? Why does the Tomcat instance not use $CATALINA_BASE/[common|shared]/lib instead? I've tried various different ways but the only one that works is the CATALINA_HOME approach. From the JNDI Datasource HOW-TO: NOTE: Third Party drivers should be in jarfiles, not zipfiles. Tomcat only adds $CATALINA_HOME/common/lib/*.jar to the classpath. NOTE: Do not install these jarfiles in your /WEB-INF/lib, or $JAVA_HOME/jre/lib/ext, or anywhere else. You will experience problems if you install them anyplace other than $CATALINA_HOME/common/lib. There may be something blindingly obvious that I am missing here but it seems to mean that you can only have a partially shared tomcat installation. Resource jars from the different instances have to be placed in the CATALINA_HOME common area somewhat negating the benefits of using a separate server via CATALINA_BASE.

RE: Tomcat 5: Location of 3rd party JNDI datasource jars in $CATALINA _HOME/common/lib
If a class needs to be accessed by both server components and web apps, it must be in the common classloader. The classes in the common class loader are all in $CATALINA_HOME. $CATALINA_BASE is for instance specific information, and the shared class loader is for classes that only need to be available to web apps (not server components); all $CATALINA_BASEs share the same server classes. The unpredictable behavior mentioned is that the classloaders that web apps use do not necessarily delegate to their parents (ie, by default they prioritize the local version of a class), which means you might get nasty class definition errors if you put copies of the same classes in, say, shared/lib and server/lib.

Also note that Tomcat-5.0.24+ is very strict about objects in the session being serializable (where 5.0.19 was less so). Upon application shutdown, non-serializable attributes will be removed so that upon restart, the non-serializable attributes won't exist in the session. Not sure if that is your problem here, but it's a good thing to note. http://archive.apache.org/dist/jakarta/tomcat-5/v5.0.25-alpha/ Jake Well, yes and no. That is, on the remote server it is 5.0.19 but locally on my laptop (Win2K) and on a Linux box (FC1) I downloaded and installed 5.0.24. I wrote a pair of simple test jsp's and the version on the Win2K machine certainly has problems as the session is different on every submit. The remote server and the Linux box seem better. After reading your note I uninstalled the 5.0.24 version then downloaded and installed the 5.0.25-alpha version (the alpha part scared me which is why I went with the 5.0.24 before). Interestingly enough it also seems to exhibit the same behaviour (new session on every submit). I guess this means that all the straining and heaving to get things to work on a local Tomcat 5 server before deploying them remotely was a wasted day.

RE: Tomcat 5: Location of 3rd party JNDI datasource jars in $CATA LINA _HOME/common/lib
Thanks for the info Ben. The only counter argument I have is ...$CATALINA_BASE is for instance specific information Making a datasource reference available to a single instance would imply CATALINA_BASE. ALL Tomcat instances would imply CATALINA_HOME. It's a picky point and maybe I misunderstand the use of CATALINA_BASE. To me CATALINA_HOME is the a basic installation and CATALINA_BASE is the fully configured instance (including shared resources). Not every instance based off a shared tomcat installation would use the same resources. Dtasources would be specific to individual instances.

Why is it that the required jars for 3rd party JNDI datasource (such as JDBC pools) have to be placed in $CATALINA_HOME/common/lib? Why does the Tomcat instance not use $CATALINA_BASE/[common|shared]/lib instead? I've tried various different ways but the only one that works is the CATALINA_HOME approach. From the JNDI Datasource HOW-TO: NOTE: Third Party drivers should be in jarfiles, not zipfiles. Tomcat only adds $CATALINA_HOME/common/lib/*.jar to the classpath. NOTE: Do not install these jarfiles in your /WEB-INF/lib, or $JAVA_HOME/jre/lib/ext, or anywhere else. You will experience problems if you install them anyplace other than $CATALINA_HOME/common/lib. There may be something blindingly obvious that I am missing here but it seems to mean that you can only have a partially shared tomcat installation. Resource jars from the different instances have to be placed in the CATALINA_HOME common area somewhat negating the benefits of using a separate server via CATALINA_BASE.

The integer i should be the length of your result set (by the way, don't
get confused with RecordSets which are VB - I used to do that all the
time!) at the end of the loop - assuming of course that you start from
the start of the set, you could use rs.first() to ensure this.

If the result set is scrollable you can iterate through it counting the number of

The other option (one I prefer) is to load the records into an ArrayList, you can then
determine the size quite easily.

A faster aproach if you are using TYPE_SCROLL_INSENSITIVE is to call

I use this all the time and have not had any problems as of yet.
To get back to the beginning is to then call rs.beforeFirst()

RE: Tomcat 5: Location of 3rd party JNDI datasource jars in $CATALINA _HOME/common/lib
I understand where you're coming from. Maybe Yoav will correct me if I'm wrong, but the important caveat is that classes are only specific to the instance if the app server classes don't need to know about them. The problem with JNDI is that the naming context is created by the app server, and not the web app - but of course, the web app is the one that uses the naming context. If you wanted to isolate the drivers by instance, you could forego JNDI as the access mechanism for the JDBC pools (create some singleton pool in the shared classloader, etc.)- although this would need kludging some things like password files, etc. It would, though, give you some ways to leave the code in shared/lib.

Why not just leave the JSP's in the iPlanet docroot, but use a service directive for the .jsp file extension to send all of those requests to Tomcat? Then you just need to make the iPlanet docroot the docbase for the root webapp in Tomcat. That's what I'm doing with iPlanet 6 right now, and it seems to be working just fine. Benjamin J.

jk2 cluster groups
Hello There, I finally managed to install and configure modJk2 with Apache 1.3 and Tomcat 5. It's running fine and the new graceful shutdown functionality is doing a good job :-) Now I want to set up in memory session replication. The problem I see with that is when I shutdown the first node, deploy the new code and restart it I would have two nodes running on a different code basis trying to replicate session information. The newly started Tomcat instance gets all the session data from the running node before it eventually opens all the ports and lets people connect to it, doesn't it?! There's now switch enabling me to activate and deactivate session replication on runtime (like JK2 offers configuration reloading by accessing the jkstatus page). Please correct me if I'm wrong... Assuming the above I think I'll need FOUR tomcat instances (1a, 1b, 2a, 2b) to implement a real failover solution. I would assign two instances to one group (1a, 1b) and the other two to a second group (2a, 2b). The tomcat instances would replicate session states just with other instances in the same group, i.e 1a with 1b and 2a with 2b respectively. This way I would be able to graceful shutdown one group (e.g. group 1) and deploy the new code without affecting the other group (e.g. group 2). Also one of the tomcat instances could fail (e.g. 1a) because there is always a 'backup node' in the same group (1b). Now the question (sorry for the long introduction to my problem): How can I assign the tomcat instances to different groups running under the same loadbalancer? Is that possible at all or is there a better solution for the scenario described above? Thanks TJ - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: session data in Tomcat 5
Certainly ! They are attached (please don't laugh at them tooo much ) BTW, I'm finding that my test server on FC1 (Tomcat 5.0.24) is working quite well, fast response, can deploy, undeploy reliably and sessions seem to work as expected. On Win2K however the 5.0.25 version is considerably slower, often has to be re-started to get a successful deploy and every touch is a new session. This is as configured by the installer (I have not changed any of the config files other than setting up a manager id/pwd) and the only change on install was to modify the install directory from c:\... to d:\... In the past I've had Tomcat 4.0 4.1 working solidly on Win2K even jk'd to Apache.I must admit that I'm not a Tomcat expert, our main deployment platform is IBM's WAS but I like to make sure that our product runs on Tomcat as some prefer a different servlet container. I guess what I'm trying to say is I wonder if some of my woes have been due to trying to use Tomcat 5 on my Win2K laptop rather than a real server box.

RE: Tomcat 5: Location of 3rd party JNDI datasource jars in $CATA LINA _HOME/common/lib
I couldn't agree with you more about the logical differences between the web app(s) and the app server itself. However, I would have thought that the CATALINA_BASE is the instance of the app server which requires the classes and not the raw installation in CATALINA_HOME. I am trying to understand why jars in $CATALINA_BASE/common/lib are not included in the app server (common classloader) classpath. The base common/lib augments the home/common/lib. I realise that there will be problems if you placed conflicting versions of the jars in the base that were already in the home but if you were halfway sensible that wouldn't be done. Cheers again, Chris -Original Message- From: Benjamin Armintor [mailto:[EMAIL PROTECTED] Sent: 21 May 2004 15:27 To: Tomcat Users List Subject: RE: Tomcat 5: Location of 3rd party JNDI datasource jars in $CATALINA _HOME/common/lib I understand where you're coming from. Maybe Yoav will correct me if I'm wrong, but the important caveat is that classes are only specific to the instance if the app server classes don't need to know about them. The problem with JNDI is that the naming context is created by the app server, and not the web app - but of course, the web app is the one that uses the naming context. If you wanted to isolate the drivers by instance, you could forego JNDI as the access mechanism for the JDBC pools (create some singleton pool in the shared classloader, etc.)- although this would need kludging some things like password files, etc. It would, though, give you some ways to leave the code in shared/lib.

An alternative is the following:
ResultSet rs;

while( rs.next() ) {

}
The integer i should be the length of your result set (by the way, don't
get confused with RecordSets which are VB - I used to do that all the
time!) at the end of the loop - assuming of course that you start from
the start of the set, you could use rs.first() to ensure this.
There's tons of useful info on Java methods and classes on suns site:

Also look on www.sun.com for good java mailing lists where this kind of

If the result set is scrollable you can iterate through it counting the number of
iterations, then set it back to the start when you want to process the records.
The other option (one I prefer) is to load the records into an ArrayList, you can then
determine the size quite easily.
If anyone else has any neater solutions i'd like to hear them too as I've had to do

A faster aproach if you are using TYPE_SCROLL_INSENSITIVE is to call
rs.last() then call rs.getRow()
I use this all the time and have not had any problems as of yet.
To get back to the beginning is to then call rs.beforeFirst()
then begin using as usual.
Hope that helps.

Re: RE: Re: Tricky situation
Yes thats a good idea.. I am very much interested to know how have you done that using iPlanet... I will try the same over here (can u pls give the exact file name and command u used) our corporate vision is to remove iPlanet and want to use tomcat for serving pages in the future... [So I keep this thread still open for ideas] -Raj Why not just leave the JSP's in the iPlanet docroot, but use a service directive for the .jsp file extension to send all of those requests to Tomcat? Then you just need to make the iPlanet docroot the docbase for the root webapp in Tomcat. That's what I'm doing with iPlanet 6 right now, and it seems to be working just fine. Benjamin J.

RE: session data in Tomcat 5

They are attached (please don't laugh at them tooo much ) BTW, I'm finding that my test server on FC1 (Tomcat 5.0.24) is working quite well, fast response, can deploy, undeploy reliably and sessions seem to work as expected. On Win2K however the 5.0.25 version is considerably slower, often has to be re-started to get a successful deploy and every touch is a new session. This is as configured by the installer (I have not changed any of the config files other than setting up a manager id/pwd) and the only change on install was to modify the install directory from c:\... to d:\... In the past I've had Tomcat 4.0 4.1 working solidly on Win2K even jk'd to Apache.I must admit that I'm not a Tomcat expert, our main deployment platform is IBM's WAS but I like to make sure that our product runs on Tomcat as some prefer a different servlet container. I guess what I'm trying to say is I wonder if some of my woes have been due to trying to use Tomcat 5 on my Win2K laptop rather than a real server box.

SSL shutdown after socket write error
Hi, I am developing a couple of web apps and have been getting the following exceptions appear in the log file: java.net.SocketException: Software caused connection abort: socket write error Until recently I have just been ignoring these errors as they didn't affect the functionality of the system. However, I have just added an SSL connector to tomcat which works on my development server, but on the live machine every time I get one of these exceptions over a secure connection, the SSL connector is apparently shutdown as no further requests to https:// respond. I have to restart Tomcat and then it's up for a very short time until the expection is thrown again. The exceptions seem to occur when navigating through pages quickly (not waiting for them to load entirely). I'm not worried about stopping the exceptions occuring just stopping the secure connection from going down. Any help would be greatly appreciated.

RE: Tomcat 5: Location of 3rd party JNDI datasource jars in $CATA LINA _HOME/common/lib
CATALINA_BASE allows you to have separate config files and a separate shared/lib (along with a separate webapps and work dirs). However, most everything such as core libraries in server/lib and common/lib are used in each CATALINA_BASE instance. I guess it would be nice if there were a place to put jars which the core server can see, but can be different per/CATALINA_BASE. For instance when configuring a datasource, one app might need a certain set of, say... Oracle drivers while another might need different ones. Tomcat must be able to see the driver in order to use container managed datasources but, as things stand, the only place to put them is in common/lib which would be seen by all CATALINA_BASE instances. The only solution is to have two entirely separate Tomcat installs. I think that is what you'll have to do unless the classloading hierarchy gets changed. As a side note (and this probably wouldn't solve the problem above, but...) it would be nice if Tomcat supported the deployment of ear files, but only used them for deploying contained .war files and shared libraries (not EJB's, of course). That would make deploying related apps and shared libs so much easier and under the control of the developer/deployer rather than the server admin since. Anyway, just a thought. Jake Quoting CARROLL, Chris, FM [EMAIL PROTECTED]: I couldn't agree with you more about the logical differences between the web app(s) and the app server itself. However, I would have thought that the CATALINA_BASE is the instance of the app server which requires the classes and not the raw installation in CATALINA_HOME. I am trying to understand why jars in $CATALINA_BASE/common/lib are not included in the app server (common classloader) classpath. The base common/lib augments the home/common/lib. I realise that there will be problems if you placed conflicting versions of the jars in the base that were already in the home but if you were halfway sensible that wouldn't be done.

Maybe Yoav will correct me if I'm wrong, but the important caveat is that classes are only specific to the instance if the app server classes don't need to know about them. The problem with JNDI is that the naming context is created by the app server, and not the web app - but of course, the web app is the one that uses the naming context. If you wanted to isolate the drivers by instance, you could forego JNDI as the access mechanism for the JDBC pools (create some singleton pool in the shared classloader, etc.)- although this would need kludging some things like password files, etc. It would, though, give you some ways to leave the code in shared/lib.

The only counter argument I have is ...$CATALINA_BASE is for instance specific information Making a datasource reference available to a single instance would imply CATALINA_BASE. ALL Tomcat instances would imply CATALINA_HOME. It's a picky point and maybe I misunderstand the use of CATALINA_BASE. To me CATALINA_HOME is the a basic installation and CATALINA_BASE is the fully configured instance (including shared resources). Not every instance based off a shared tomcat installation would use the same resources. Dtasources would be specific to individual instances.

The classes in the common class loader are all in $CATALINA_HOME. $CATALINA_BASE is for instance specific information, and the shared class loader is for classes that only need to be available to web apps (not server components); all $CATALINA_BASEs share the same server classes. The unpredictable behavior mentioned is that the classloaders that web apps use do not necessarily delegate to their parents (ie, by default they prioritize the local version of a class), which means you might get nasty class definition errors if you put copies of the same classes in, say, shared/lib and server/lib.

Re: session data in Tomcat 5
Well, it works for me on Win2k with Tomcat-5.0.25. Same session every post. You don't have sessions turned off in web.xml by setting the session-timeout to 0 or -1 (can't remember which one, if any, disables sessions) by chance, do you? You might also check for virus or firewall softwared/hardware on your machine. That stuff can mess things up pretty badly. Jake Quoting M.Hockings [EMAIL PROTECTED]: Certainly !

Re: session data in Tomcat 5
I just dropped your JSPs in a box running win2k server and tomcat 5.0.24. They run fine, same session. Once the strings are created, they stay created, no nulls. I'm hitting from a linux box using Mozilla, but I also tried from MSIE on the machine that's hosting your JSPs. All looks good. For kicks, try doing this: In MSIE, click Internet Options - Privacy (tab) - Advanced (button) Then check the Always Allow Session Cookies checkbox. Let me know if that fixes it. -good luck On Friday 21 May 2004 10:36 am, M.Hockings wrote: Certainly !

RE: Problem with error-page
I'm not shure about the response code that is returned in both cases. It's possible that tomcat returns a different response code for a html and a jsp. (Like 200 for html because the html error page was found and some other value for the jsp because the jsp explicitly sets an response code.) Some recommendations to verify that: - Listen with a tcp monitor and watch the headers. - Use a browser (or other tool like telnet) that is able to display the headers . -Original Message- From: Jim Kennedy [mailto:[EMAIL PROTECTED] Sent: Friday, May 21, 2004 6:30 PM To: 'Tomcat Users List' Subject: RE: Problem with error-page The suggestion to change 403.jsp to something like _403.jsp did not work.

If the class is in the webapp's libraries, it's going to try to cast it to an instance of the webapp version of the class, which will be different from the version the valve created.

It seems Tomcat somehow lost the class structure of the original info class...? Anyone got a clue of this? Sounds like a ClassLoader problem. The valve is going to use tomcat's libraries. The filter will use the webapps's libraries, in preference to tomcat's libraries. If the class is in the webapp's libraries, it's going to try to cast it to an instance of the webapp version of the class, which will be different from the version the valve created.

Re: Pass info between Tomcat Valve and Filter
Cool. I guess a Valve is good for that type of thing :) I think Carl and Ralph are right about the ClassClassException being a ClassLoader issue. I've seen similar things before when using custom Realms, JNDI resources etc. Our build process generates a minimal jar for deploying to common/lib which contains all the classes needed by the container classloaders. These classes are excluded from the webapp jars and all is happy. You have to be really careful about dependencies though or virtually all your webapp ends up in common/lib. Try jarring up your info object and putting in common/lib (or common/classes). Or you could use reflection as I've just read in your reply to Ralph ;) Good weekend all, Jon Rui Zhang wrote: Jon, To answer your query, I'm using a custom valve to instrument Tomcat with response time monitoring, as part of the project I'm working on... http://web.comlab.ox.ac.uk/oucl/research/areas/softeng/eWLM/ Cheers, Rui On Fri, 21 May 2004, Jon Wingfield wrote: An invocation of a Tomcat Valve gives you a Request object.

RE: CGIServlet -- tomcat
Alex,
I have been looking after the CGI servlet for the last few months. If you look
in CVS you'll see my name against most of the changes.
Sorry I didn't see your early posts on the user list. I do keep my eyes open for
anything CGI servlet related and must have missed it.
Is the header issue the only one?
I am no perl expert, so if you could post a complete (but as simple as possible)
script test case that doesn't work that would be a big help.

RE: webdav servlet problems with Tomcat 5.0.24 and IE
From: Roy Gardner [mailto:[EMAIL PROTECTED] Do you know how the TC4 handles the redirection issue? We have a webapp to which we are adding webdav support. Our webdav implementation has exactly the same problem as the TC5 implementation when using IE clients. If we set the url-pattern to /* we break our webapp. From what I recall TC4 doesn't actually do a redirection, it handles it inside the mapper. TC5 Sends a 302 - this is what IE seems to have difficulty with in some circumstances although I can't replicate the error now with either mapping. I have searched bugzilla for this and there is more info at http://nagoya.apache.org/bugzilla/show_bug.cgi?id=26449 from the last time I looked at this. The essence is that welcome file behaviour also causes problems. Try specifying welcome-file /. - does it work if you run TC5 on a windows box? Have not tried this. I'll install on one of our boxes and test. Let me know how this goes. What happened with the telnet tests?

I've seen similar things before when using custom Realms, JNDI resources etc. Our build process generates a minimal jar for deploying to common/lib which contains all the classes needed by the container classloaders. These classes are excluded from the webapp jars and all is happy. You have to be really careful about dependencies though or virtually all your webapp ends up in common/lib. Try jarring up your info object and putting in common/lib (or common/classes). Or you could use reflection as I've just read in your reply to Ralph ;) Good weekend all, Jon Rui Zhang wrote: Jon, To answer your query, I'm using a custom valve to instrument Tomcat with response time monitoring, as part of the project I'm working on... http://web.comlab.ox.ac.uk/oucl/research/areas/softeng/eWLM/ Cheers, Rui On Fri, 21 May 2004, Jon Wingfield wrote: An invocation of a Tomcat Valve gives you a Request object. This is a facade to a ServletRequest, which you can access via the getRequest() method. You could set your info object as an attribute on the ServletRequest. This should then be visible to your filter. http://jakarta.apache.org/tomcat/tomcat-4.1-doc/catalina/docs/api/index.html Just curious, why the custom Valve?

jakarta-tomcat-5.0.24.tar.gz really a Windows Dist?
Maybe a silly question. Seems the jakarta-tomcat-5.0.24.tar.gz is really a Windows binary distribution. And then the jakarta-tomcat-5.0.24.zip contains both Windows and Unix distribution. Am I out of my mind here or can someone please confirm what I'm seeing is true? Thanks. Dan Barron - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
