5:18 a.m.
I am trying to cluster 2 JBOSS instances running on different server. The cluster deploy
works fine without any problem. If I take one server down it is removed from the cluster.
If I start the server it is added in cluster without any problem. I have Configured
external Load Balancer using mod-jk. However, it is not replicating sessions on cluster.
i.e. If I am accessing the web app on load balanced URL and shutdown the server on which
request is going I again get the login page instead of session being continuous. When
checked the logs I get following error.
