I have overloaded the SessionCleanup and setup the listener in zk.xml.
If I call session.invalidate() my cleanup class get's called. The problem I am having is that it does not get called if the user goes to a different URL from my application, or if the user closes the browser.
I have checked the docs and could not find anything on this.
So what I want is for my session cleanup class to get called when the user leaves my application by going to a new URL or by closing the browser.
I swear I had a sample app that did this last year but can't find my code (of course).
All help appreciated

My Files listings :

In my web.xml :

<description>Used to cleanup when a session is destroyed</description>
<display-name>ZK Session Cleaner</display-name>
<listener-class>org.zkoss.zk.ui.http.HttpSessionListener</listener-class>
</listener>
..

In my zk.xml :
<zk>

<!-- NOTE Hacked my jboss install to create the conf directory under /opt/jboss../bin so
that ZK could find my i3-log.conf file. Need to figure how to to tell ZK where to find
it instead of me moving it. -->
<log>
<log-base>org.zkoss</log-base>

</zk>

and my class :

public class DHzSessionCleanup implements SessionCleanup {
private static Logger logger = Logger.getLogger(DHzSessionCleanup.class);

public void cleanup(Session session) throws Exception
{
logger.info("\nDHzSessionCleanup::cleanup" + session.getLocalName());
}

}
