I checked out JBM2 code from SVN (revision 6038) and did the following: - Build the code. - Installed the build to 2 different Linux servers. - Configured the cluster (I set the tag "clustered" to true). - Configured a valid multicast ip address. - I saw that the "rmi.server.hostname" was not injected so I added the following to "run.sh" to fix the issue "-Djava.rmi.server.hostname=" Then I started both servers - all the examples were working fine in both nodes (servers) except the ClusteredQueueExample. [TextMessage message2 = (TextMessage) messageConsumer.receive(5000);] message2 was null which means the cluster didnt work for me. Could you please tell me what I am missing? I set the logging to DEBUG mode but didnt see significant information about the cluster failover -Abdel View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4216287#...
