I guess this is the behavior that is described as cluster in the Jboss Messaging Documentation. | Chapter 7. JBoss Messaging Clustering Configuration | ... | | JBoss Messaging also supports clustered temporary topics and queues. All temporary topics and queues will be clustered if the post office is clustered | ... | | This is just message routing between multiple server nodes..? I would argue that a Clients Connection is with the Cluster, not a specific node within the cluster. The specific node connection is a temporary 'internal' state for the cluster connection. When the Cluster Connection does a failover, the internal state changes, but the Clients ClusterConnection remain the the same. -aslak- View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4085437#...
