Automatic Redirect to Login page on Session Expire

[Deepanjali Reddy]

Hi,

Is there any way to handle the session expiry event from web.xml?

usually we will do it in a servlet by checking the session expiry time and if it is expired, we will redirect it to another jsp which is usally the login page with a message saying that the session has expired.

but is it possible to do it from web.xml? i mean in an existing application, where we have thousands of servlets, it is not possible to handle the event in each servlet. I was just checking is there any other way of doing it in a centralized way.

Thanks .
Deepa.

Try using httpSession listener descriped in javax.servlet.http package.

Actually, the best way to handle this is with a filter. That way, the checking code doesn't need to be called from each and every servlet.

A listener isn't a good choice because it's not tied to the request.
