Hi Chris, Session.invalidate() is being called by Tomcat on session timeout, which is the same call that is given when you implicitly invalidate the session in your servlet code. Once session.invalidate() has been called, you no longer have any session properties to get, including your session listener. Also, you're gonna need to add some properties to your session object to determine how/why the session was invalidated. Just using the API calls without any "support staff" will not be sufficient.
