[jboss-user] [Clustering/JBoss] - Re: Unable to run multiple cluster nodes.

I see three things in the server.log

1) The logging subsystem is complaining. Have you packaged log4j.jar in your war? If yes, recommend you remove it if you can.

2) You nextapp.echo2.webcontainer.ContainerInstance class is throwing an NPE. Can't help you there.

3) Your code is trying to pass an object that doesn't implement java.io.Serializable as a value to HttpSession.setAttribute(String key, Object value).  That is not allowed, as all attributes need to be serialized for session replication to work.
