RE: Tomcat problem

Lots of possibilities here, but it is likely an application issue.  I
presume that it is using JSP's for the screen interface?  

 

Is there any sort of persistence layer being used?  Does the application
start and stop threads?  Does it use thread-safe methods or do its own
synchronization?

 

Tomcat is essentially a JVM container.  The Java application code has to
support threading (using locks) or use thread-safe methods or it will crash.

I have 5 users clicking 'submit' at the same time.  And this causes a heap
dump.  Tomcat hosts the App.   I assume it is a threading problem or locked
sessions causing the problem.

can you be a little more specific about what the problem is? Tomcat is just
a webserver? What do you mean by threading? What is being threaded? Do you
just mean the same webpage launched by multiple users?
