first, use a META tag for monitoring the max session inactive timeSee code below..<meta http-equiv="refresh" content="<%= session.getMaxInactiveInterval() %>;url=error.jsp">

Hi ,

I ran into another problem using the code below

When MaxInactiveInterval Period over the error.jsp page gets displayed . But then sessionListener notifies that session gets destroyed after another 10 minutes which is set in web.xml under <session-timeout> .

Is the reason for this is page refresh is an activity and container terminates the session after 10 mins.

If so how this can be resolved ?

Thanks

Maybe you're overridding maxInactiveInterval manually using HttpSession#setMaxInactiveInterval()? If so, don't do that if you want to use the time-out as it is definied in the web.xml.

Yep It was there but i removed setMaxInactiveInterval() to avoid overriding the web.xml setting. Still the problem is there

Is it the "refresh" in meta tag which causes some page activity.As am noticing in HtpsessionListener the

sessionDestroyed(HttpSessionEvent arg0)method gets invoked 15 mins after the error.jsp is displayed .

I need this method be invoked immediately inorder to remove session objects from SessionMap in jsf.

Is there any other way i can acheive it.?

Thanks
