Asynchronous consumer doesn't consume?

Question

Can anyone tell my why my message consumer doesn't consume a TextMessage put in a Queue by a MessageDrivenBean?
Another part of my client successfully sent a message to the MDB, and the MDB put a TextMessage in another Queue (queue\goAdminOut) with this property set on the message:
key="Selector"
value="ADCD"
I know the TextMessage is waiting on the Queue, because I can see it using the servers web-consloe.
Its just that the message does not trigger the onMessage () method of the Listener I set on the MessageConsumer in my client.
The MessageConsumer was created with:
Session.createConsumer(Destination destination, java.lang.String messageSelector)
Here is a list of the relevant code included below.
1. Two classes the mimic my client.
TestConsumerView
-- A JFrame that stays alive till it is closed.
TestConsumer
-- An object that is instantiated as a field in TestConsumerView
-- It establishes the connection, session and message consumer
2. The screen print when I run TestConsumerView
3. A screen print from the JBoss JMX web console confirming that the message is in the queue

Sorry,
I guess I screwed up and put TestConsumerView code twice.
Anyway, the missing TestConsumer code is below.
I am not sure I understand your comment about MDB and a Java GUI client.
Right now I am testing my app on a local server.
Ultimately I intend to use a remote server that mediates between two WebStart downloaded Java GUI clients running on independent PCs.
Kind of a game model with two players.
Both clients can send ObjectMessages to a server side Queue that is listened to by an MDB (i.e. the object would contain all the data needed to enroll a new player, or to describe a new play by one client to the other).
The MDB would process the data in the object attached to the Object Message using Entity Beans and any other server side components required, i.e. to add the new member to the database or update the copy ot the game history.
When done, the MDB would send messages to one or two Queues.
Queue-1 would be listend to by the client that sent the origianl ObjectMessage letting it know if the object was processed correctly.
That is why I want to use a selector. There could be multiple pairs of clients being served by the MDB, so I need to attach a selector to the original Object message that the MDB then sets on its response message so the original client can find the MDB response in Queue-1.
Queue-2 would be listened to by the other client (i.e. to let it know a play has been made). Same concept.
Right now I am just trying to test the original client cycle, i.e. the original client listening to Queue-1 to see if the MDB succeeded.
The Object message to MDB and the MDB message to Queue-1 works because I can use the JBoss web-consloe to see the TextMessaage waiing with the correct selector in the correct Queue.
I just can't seem to write code for an asynchromous consumer in the original client that continuously listens to Queue-1.
Anyway here is the code.
