Tomcat JSP session beans not being removed at the end of the session

[John Smith]

I am using Tomcat 4.0. I have a number of JSP beans with scope="session".
The beans a simple and do not contain any circular references. When a
session times out I have noticed the beans are not cleaned up. I have
checked this by adding a finalize to the classes and this does not indicate
them being removed.

Any ideas?

Thanks Jon

Are you sure that GC has been run? Invalidating a session just
removes the reference, your finalize won't show up until GC runs.

Tomcat is made with java and like all java applications memory is freed
by garbage collector and finalize method is called when gc is going to
free object from memory. If you need information about when session is
dying use javax.servlet.http.HttpSessionListener interface.
