Are there 2 seperate jvm's in WAS..to explain further if i am deploying my ear file in WAS then will the call to ejb be local or remote? Are their seperate web and ejb container and do they run on seperate jvm's?
Cluster == multiple server instance, and there for multiple JVMs. Still though deployed on one server, classes in an EAR and a WAR will run in the same JVM.
