I have an old web app in JSP. Now I'm trying to apply some changes with ZKJSP. When I use the application it seems to be perfect and the session is replicated between both instances. But after click 3 or 4 links the session crash and the navigator creates a new one and everything start to fail.

If I unplug ZK, the session always replicates perfectly, so, it only fail when i deploy the webapp with ZK.

Also the webapp with ZK runs perfect when the app is deployed without cluster environment.

Finally, i think that the problem is when you mix ZK + glassfish Cluster.

I have tried this zk.xml configuration and also without the ClusterSessionPatch listener.

<system-config>
<ui-factory-class>org.zkoss.zk.ui.http.SerializableUiFactory</ui-factory-class>
</system-config>
<listener>
<listener-class>org.zkoss.zkplus.cluster.ClusterSessionPatch</listener-class>
</listener>
