The tomcat clustering is not compatible with JGroup.
Thanks Jean-Frederic for reply.
I haven't enable the tomcat/jboss cluster yet. I have setup the non-cluster environment for testing.
I also tested Event notification by using 2 tomcat and it's working fine.
Issue is that when we try to test application with different container i.e one JBOSS and other TOMCAT. the event notification works doen't work
Note : For event notification we are using JGroup.
ok that looks like a question for Jgroups then, please ask them.
