This is a thread discussion on http://jira.jboss.com/jira/browse/JBMESSAGING-578. For a call on JChannelFactory, we are supposed to send an ID identifying the system. We could have a constant (such as JBOSS_MESSAGING) on that ID, but per my discussion with Brian Stansberry we should have the ID configured. Briand recomended using ${jboss.partition.name:DefaultPartition}-JMS for the Application Server. I will keep the partitionID configurable on the ClusteredPostOfficeMBean then.
