I made a mistake in my post. the two servers are started up with the commands: Server1 ./run.sh -c all -b 10.200.90.103 -Djboss.messaging.ServerPeerID=10 -Djboss.messaging.groupname=TestPostOffice -g TestPartition1 Server2 ./run.sh -c all -b 10.200.90.105 -Djboss.messaging.ServerPeerID=11 -Djboss.messaging.groupname=TestPostOffice -g TestPartition1 Thanks for your time, Patrick View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4241568#...
