The ClusterRoundRobingDistributor aways favour the local queue on the Cluster.

   public Delivery handle(DeliveryObserver observer, MessageReference ref, Transaction tx)
  |    {             
  |       //First try the local distributor
  |    	
  |    	if (trace) { log.trace(this + " first trying with local distributor"); }
  |    	
  |    	Delivery del = localDistributor.handle(observer, ref, tx);
  |    	
  |    	if (trace) { log.trace(this + " local distributor returned " + del); }
  |    	
  | 
So.. if you have your MDB on ServerA and Producer on ServerA, the MDB on ServerA will aways receive the messages.


If you were sending to a ServerC with no consumers on it, then the load would be balanced between ServerA and B.

If you need that kind of load, you could be using two producers, on two distinct connections created by a ClusteredConnectionFactory.
