[syed mraza]

hi everyone
I'm performing some actions whn user logs out (hence session invalidates) If i have a *friendly user* means user logs out properly then every thing is ok. but if s/he doesnt? then how to know wht session times out??? and how can i perform those actions on session time out? is there anny thing like session listener??? actualy Servlet 2.3 does have session listener but unfortunately i'm using servlet 2.2. any help/suggestion/idea would be realy appriciated.
thnx

You can implement the HTTpSessionBindingListener interface. When the session terminates, any object object that's bound to the httpSession object will get unbound.
