Catching Jboss shutdown notification

[general]

Hi

I find it is really a challege for web developers to do something when user logouts. Because they don't know when user logouts, especially under this case: admin shuts down Jboss. It seems they don't get any chance to show their coding talent.
Before I thought session listeners in web appliaction could get such a chance. I thought Jboss would destroy all the sessions so I could listen to the session-destroyed event. Today it was proved that this is not correct. No such a event happened when admin shut down Jboss.
Is there a way to catch such a similar event? Such as monitor, notification listener or any others?

Thanks!

Its a known issue that is being looked at:

Thanks, scott! Let me know servlet context can get a notification.

I looked at that bug following the URL. I think it is a bug only on single machine. Web server and app server are on the same machine. For distributed environment, whether it is a bug depends on the sequence which admin shuts down the web server and app server following. If admin shuts down web server before app server, then that it not a bug. However if admin shuts down app server firstly, it is still a bug except that when app server is shutting down, it notices web server and then web server terminates automatically.
