RE: How to detect that session has expired ?
If you use container authentication or filters, this isn't an issue. The user will never get to an action class with an invalid session.

Re: How to detect that session has expired ?
When a session restarts, its context is empty, so all objects stored in the session context have disappeared. To detect if a session has restarted, you need first to store an object in the session context, then each time you need to know if the session has restarted, you test its presence in the context. If it is not there anymore, then the session has restarted.

RE: How to detect that session has expired ?
Thomas, You mean to say that I should put this logic in ActionClass. But then I would need to put it in all my Action Classes. Can't I do something similar in JSP because then I would do it in a common JSP which is included in all other JSPs of mine. Or is there a common solution which can take care all Action Classes.

RE: How to detect that session has expired ?
Seems this is not supported by many containers yet(J2EE 1.4). You could use a filter to check for session expiry but what if it expires after it passes the filter. Then each JSP should have a check in the beginning.

RE: How to detect that session has expired ?
You ought not to refer directly to any jsp pages anyway. Always refer to an action which forwards to your jsp. Then you can put your JSPs inside WEB-INF if you want (insures they can never be directly accessed) and you never have to add any tag(s) to check for valid user. As Ed points out, Inheritance is your friend. Get to know him, and his cousin, Poly. Poly Morphism.
