how to check session has been expired in java?

Question

Is there any other way to check expiry of session other than this

session.isNew()

Answer 1

Yes:

• you can call HttpServletRequest.getSession(false) and you'll get a null instead of a session if there isn't one active already.

• you can define a lifecycle listener (using HttpSessionListener) in your web.xml. That way you can get notified the moment a session bites the dust.
