Is there any alternative for this method
HttpSession's getLastAccessedTime();
Thank you in advance.

Hi Ansari
Thanks for reply..
Iam assigning HttpSessionBindingEvent.getSession() to HttpSession variable in a Listener class..
what I need is getLastAccessedTime();and getMaxInactiveInterval()...iam able extract maxInactive interval time...but when I invoke getLastAccessedTime()..it is throwing IllegalStateException....
I thought if there is any alternate way...
Thank you

Well, we encounter IllegalStateException upon invoking getLastAccessedTime() on an invalidated session. Whereas the other method will give you the result anyway.

Can you show the code snippet?

hi Ansari,
I knew that it is being invalidated session..
it goes like this.....
HttpSession session = bindingEvent.getSession();
long l_access = session.getLastAccessedTime();
......
Thanks

Thats what the API says - binding listener gets called when the container is invalidating the session.
So why not make your session variable hold its own copy of the access time, updated every time the session is accessed.

You can set the last accessed time as your session attribute upon each request.

Something like below



I hope you get the point.

As I understand it, you have created a class implementing HttpSessionBindingListener and attach an instance of this class to each new session. In the valueUnbound method you are trying to get at the session with the Event getSession() method so you can use the session method getLastAccessedTime() - this fails because at this point the session is invalid.

What I am saying is to add a timestamp variable to this custom class - update it everytime you process a request. When the valueUnbound method is called you will have the last access time in the object and wont have to call a session method.
