Ok, I finally got everything up and running on JBAS 4.2.2.GA and JBM 1.4.0.SP1. I use a ClusteredConnectionFactory to push messages to a clustered queue, and it is round-robining them to the partial queues as expected. Each of the services consuming these messages pushes another message on to another clustered queue using XAConnectionFactory, which results in each node pushing the message to its own partial queue. The consumers of these messages are non-clustered windows servers that are both connected to one of the nodes in the cluster using the ClusteredConnectionFactory available through ha-jndi. I expected the messagesucker to move messages from the node with no consumer to the node with consumers but it is not. Is this because those message were pushed using the XAConnectionFactory instead of the ClusteredConnectionFactory?
