Notification of stale session?

[Kevin Whitley <ke...@podtech.net>]

Is there some way to receive notification that a session has become  
stale?  I'm looking for something like the javax.servlet interface  
HttpSessionBindingListener.  I have various resources associated with  
a session and I'd like to free them up when the session times out   
not waiting for somebody to hit the session (and notice it is stale).

Thanks,

There are many ways to do this, the most common and simplest is using a 
simple pageValidate, but if you need something more complex for whatever 
reason, you can also wire a listener using hivemind or even use your 
web.xml file

i.e.
web.xml
<listener>
    <listener-class>
        com.test.application.SessionListener
    </listener-class>
</listener>

public class SessionListener implements 
HttpSessionListener,HttpSessionAttributeListener  {

}

or using hivemind:
<implementation service-id="tapestry.error.StaleSessionExceptionPresenter">
        <invoke-factory>
            <construct class="application.StaleSessionListener"></construct>
        </invoke-factory>
 </implementation>

public class StaleSessionListener implements StaleSessionExceptionPresenter{
    public StaleSessionListener(){ 
    }
    public void presentStaleSessionException(IRequestCycle cycle, 
StaleSessionException exception) throws IOException {
        System.out.println("a stale session was detected");
    }
         
}
