Same for me with Messaging 1.4 and AS 4.2.2.GA Again, I presume I'm missing something ... Took an out-of-the-box configuration, using a combination of the ejb3mdb and cluster examples - deploying the MDB to both nodes and changing the client to send lots of messages (10000+) results in all messages appearing on one (either) node, and failover not working. Anyone got a simple load-balance test configuration which works please? Thanks tim View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4113838#...
