I have the need to do some cleanup work after a session ends. In ASP (oh my!) this can be done using session.onEnd in the global.asa.
How can this be done in JSP?

Hi Liz,
do you want to know when the session is destroyed ,that is ends?? If that is the case then check out API documentation for HttpSessionListener interface in package javax.servlet.http

Yes...I want to clean up some records in a table if the user ends the session. Do you know of another place that describes this more clearly than the API?

You can use class which act as session listener in your application and register it in deployment descriptor (web.xml) . It extends HttpSessionListener and implements method sessionCreated(HttpSessionEvent se) and sessionDestroyed(HttpSessionEvent se).
You can put your code for clean up in method sessionDestroyed().
The web container will invoke or notify sessionDestroyed() when your application invalidates sessions or the sessions are timeout.
Hope this help...
Correct me if i am wrong...

If you make your class that contains the data a SessionBindingListener, the object will be notified when the session is destroyed and you will have the data right there. You don't have to register a SessionBindingListener.
