J2EE - difference between using invalidate() & sessionDestroyed

preethisingh · 23-01-07, 10:47 PM

Whats the difference between using invalidate() & sessionDestroyed for sessionclosing.

**t_mohan** · 25-01-07, 01:41 PM

As far my knowledge is concerned, invalidate() methods unbinds any object associated with the servlet and invalidates or destroys the session when called explicitly

Where as sessionDestroyed() method will be called when we specify a session timeout and will be called when a session is destroyed, this will be invoked by the web container. and also when a invalidate() method is also called, it follows the execution

Let me know your questions, If im wrong , pls tell me

Thank You

tats correct mOhan.
also when u say session=null...which is a crude and most undesired way of destroying a session, as far as i feel, the sessionDestroyed method of the HttpSessionListener is called before making the session 'null'.

I definitely need some clarification ont he point I have made. any givers?....
