RE: clustering help
I have two jsp's for the same app on ebot servers(the code that sets and
retrieves the session is below). When i hit the jsp on the first server a
session is created and the id returned. Now i pass this as a parameter to
the second jsp and it retrieves the session associated with this id from the
second server and i can set the attribute value.
server 1:
<%
session.setAttribute("killer", "ant");
out.println("The session id generated is "+session.getId());
%>
server 2:
<%
String id = request.getParameter("id");
HttpSession _session =
request.getSession().getSessionContext().getSession(id);
if(_session == null){
out.println("session not available id: "+id);
return;
}
String test = (String) _session.getValue("killer");
out.println("The killer value of session with ID "+ id +" is "+test);
%>

Nandish Rudra

the logs are showing that everything is replicating fine.
you can't change the browser url when switching to the other server,
how are you testing if it works or not?

The issue is that microsoft (article Q316431) will not display a file from a SSL site if the cache is set to no-cache. It seems that Tomcat automatically generates a "Contect-Type" header that includes this parameter. I have not yet found out how to change it. If you look in the /conf/web.xml file under mime type mappings you will see this. Hopefully someone will have the answer.

We have a Tomcat 5.0.25 based web site for uploading images and assorted files and managing them.

Running Tomcat 5 Headless
Hello Everyone, Can any one tell me how to make tomcat start "headless" and what it exactly means, I am new to this term? I am running a webapp on redhat 9 machine (without X11) and using awt for manipulatiing images. The browsers look for X11 session whenever i try to access the servlets. From what I understand, a headless tomcat can solve my problem.

RE: OutOfMemory Exceptions AGAIN
Hello QM, As Matt had suggested, i check and there was a jsp from one of the other apps running, that was not invalidating sessions. I found 9000+ sessions of that jsp. The jsp now invalidates its sessions and hopefully things will be better. As the app is still under development the load is almost nothing hence the needs of the heap should not be great. I have been running the same app on my machine locally and have not had any memory issue as of yet. Thanks for the help guys.

If you look at the tomcat manager app it will tell you how many there are and you are likely to see this number increasing. The reason that it starts bloated is because when you shutdown the sessions get serialised and then reloaded once you restart tomcat. To stop it starting up bloated remove the SESSIONS.ser file from your context's work directory, while the server is shut down. As a more permanent solution you should explicitly invalidate the sessions in your code or reduce the session inactive timeout but i'd suggest the former.

One is that your webapp maintain static or shared references to objects that prevent them from being garbage collected, and therefore memory from returning to the heap. Another is that a webapp undeploy is not guaranteed to reclaim all memory used by the webapp anyways so to count on this behavior is not smart. It is expected that every time you reload your webapp the overall memory usage of the server will go up a bit, as not all objects are gone (for example, if you have a static reference than the old classloader and anything that references it strongly will remain in memory).

RE: Tomcat Out Of Memory
Hi, Chances are your app is not releasing memory properly. You can fine tune the jvm size, or use a java profiler to find where the memory leak is and fix the problem. I recommend JProbe if you wish to use a profiler.

Memory Usage - Tomcat 5.0.25
Hello Everyone, I am writing about this error from yesterday. I used JProfiler to monitor my memory usage. And am now sure that each and every static object is trashed when the application is undeployed and the profiler shows that memory is free and all instance of the objects are GC'd. This works on a Windows 2000 setup of Tomcat 5.0.25 with Java 2 SDK version 1.4.2_04 and Ant 1.6.1, but fails miserably on GNU Linux 2.4.20-8 setup. this happens with both tomcat 5.0.25 and 5.0.27 Any ideas why something like this could be happening.

One is that your webapp maintain static or shared references to objects that prevent them from being garbage collected, and therefore memory from returning to the heap. Another is that a webapp undeploy is not guaranteed to reclaim all memory used by the webapp anyways so to count on this behavior is not smart. It is expected that every time you reload your webapp the overall memory usage of the server will go up a bit, as not all objects are gone (for example, if you have a static reference than the old classloader and anything that references it strongly will remain in memory).

RE: Memory Usage - Tomcat 5.0.25
Hello Yaov, You are correct I do have a few static varibles that point to running threads and some other objects. When the application is shutdown I ensure that each thread is destroyed and all static varibales are set to null, including thread identifiers, this should let my call to GC clear the memory. You are also right in saying that i should not depend on undeploy to reclaim all memory that the webapp was using, and I don't. Like I mentioned I do make sure all static variables get set to null before the application shuts down. It would be understandable if not all memory utilized by the webapp is reclaimed, but in my case absolutely no memory is being reclaimed. For example, say, i start tomcat and it starts with 30M initial memory usage without the application. Now when i deploy the application the size jumps by 8M to 38M. As the app is undeploy and re-deploy the memory usage jumps from 38M to 46-47M. Now this, if I am not wrong, is not how things should be. I would appreciate anymore suggestion that you or anyone may have.

Memory Usage - Tomcat 5.0.25
Hello, I am having some memory issues while deploing/undeploying web applications to Tomcat. I am using Tomcat 5.0.25 with Java 2 SDK version 1.4.2_04 and Ant 1.6.1 on GNU Linux 2.4.20-8. I use ant to compile my web application and Tomcat's catalina-ant.jar to deploy it automatically. Here is my problem. When I undeploy/remove an application, Tomcat does not reclaim the memory being used by the web application and when the application is re-deployed/re-installed a significant increase in memory is seen. This increase is obviously the memory usage by the new instance of the web application. Does anyone have any idea as to why this is happening?

RE: Tomcat stops responding
Check logs for outofmemory exception. If the log has no exceptions check your memory usage.

Tomcat 4 cluster - drops members
Hello, I have an application deployed on a tomcat 4.1.30 cluster. I retrieved a jar from http://cvs.apache.org/~fhanik/ , a tomcat 5 clustering jar that has been made portable for tomcat 4. We followed the instructions and setup the server.xml for the cluster. The application is deoplyed using ant auto deployment task. Now when the cluster is started the groups is successfully established. Suppose we have two servers A and B. When a browser hits the server A, a session is created on server A and an attempt is made to replicate session to server B. During the process server B hangs and is knocked off the cluster. Any ideas why this could be happening. Nandish Rudra - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Tomcat 5 replication question
Hi, I am using Tomcat 5.27 for clustering 2 server. The web application running on thses server maintains a TreeMap that needs to be replicated across the cluster. Currently, I use JGroups to do my own clustering, but now that tomcat 5 has built in clusteing i would like to use it. I cannot use sessions to replicate the tree bacause the data is not session specific, the web application is more of a service. Is there a way of making tomcat take over the replication task and if so, what do i need to do or where can i find documentation for it?
