Message Listener Listening to only 1 queue in distributed queue setup!

Question

Hi guys,
This may be the wrong place to place this post.
We created a message system with OSB proxies moving messages back and forth between distributed queues. After all this shuffling messages around, the messages end up in a distributed queue where a java client is waiting to pick up results. Our problem is, it's only reading one of the queues in this distributed queue.
The following is the code segment that waits for the message with a specific id:
public Message receiveMessage(String queueName, String messageId) throws FrameworkException {
BytesMessage bytesMessage = null;
if (null == queueSession) {
init();
try {
Queue receiveQueue = lookupQueue(queueName);
QueueReceiver queueReceiver = null;
String selector =null;
if (null == messageId) {
queueReceiver = queueSession.createReceiver(receiveQueue);
} else {
selector = "JMSCorrelationID = '" + messageId + "'";
queueReceiver = queueSession.createReceiver(receiveQueue, selector);
bytesMessage =(BytesMessage) queueReceiver.receive();
queueReceiver.close();
}catch{...
Will queueReceiver.receive() listen to every member in a distributed queue (spread across 2 managed servers in a cluster)?
Thanks alot

Yes, the uniform distributed queue should be available on all targeted servers, providing that the jms module has been targeted to all of the OSB servers, and that your java app ( .war file? ) is targeted to both.
You can stop the java application so that messages remain in the queue "long enough" for you to see them from within the WL console. Then you can shutdown nodes in your cluster individually, so conform that the message is truly being distributed. Then the issue is whether the java app is reading from the entire distributed queue instead of just one node.
When you use the monitoring tab on your queue, do you see a queue entry for each jms server ( each mgd server needs one )?
Or is the issue that the java client is only reading from one server?
