Brian, Just went through your proposed solution - the problem with the solution is that if there are 2 clusters, each with @Clustered SFSBs with identical ejbNames, when a bean in cluster A looks up a proxy in cluster B and then invokes on that proxy, we will get a local invocation instead of the remote invocation. Seems like we need a way, other than ejbName, to identify if the container is local. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4027614#...
