Thanks. For whatever reason, that phrasing sunk in and made sense. :-) Two things... 1) I assume that the tc5-cluster.sar has been replaced with jboss-web-cluster.sar in AS 4.2.0? 2) The ejb3-clustered-sfsbcache-service.xml and ejb3-entity-cache-service.xml files don't contain example TCP stacks. Am I correct in assuming that the TCP stack definition from the cluster-service.xml file can be adapted to these other locations? (We have a cluster across subnets with firewalls that filter mcasts, thus the focus on TCP as the communication protocol.)
