First of all, are you using session scope of your bean? Or are you putting
it in the request scope?
<jsp:useBean id="bean" scope="session" class="package.BeanClassName" />
If in your controller serlvet you put the bean instance into the request
like so:
request.setAttribute("bean", beanInstance);
Then it will only go back to the JSP page as request scope..which means on
the next request to the server, the bean will be gone..its in the pool for
GC basically. Make sure you are using session scope.
As a side note, make sure if the user gets to say..an END page, that you
remove the session scoped bean from the HttpSession, so you can free up the
resources used. I have personal experience with code where it does not do
this, and we are seeing lots of memory usage problems.
