[jboss-user] [Messaging, JMS & JBossMQ] - Re: MDB and connection to a remote queue with transaction

[hoigh]

As already stated, posting to the remote queue works fine if I use

  | QueueSession session = connection.createQueueSession(false, QueueSession.AUTO_ACKNOWLEDGE);
  | 
instead of

  | QueueSession session = connection.createQueueSession(true, -1);
  | 
It makes no difference whether I use ConnectionFactory or XAConnectionFactory.

To find more details on the problem I examined the server logs and switched the logger for org.jboss.qm to DEBUG level.

Astonishingly, there seems to be no difference in the log if I use the transacted session instead of the normal one.
Here are some extracted snippets:

Sending within MDB.onMessage() on local host:

The strange exception causing the ServerSocketManagerHandler to exit on IOE seems to be independent of my original problem and is always there: no difference between successful send and failure.
Sometimes there is also an

  | java.io.EOFException
  |         at java.io.ObjectInputStream$BlockDataInputStream.readByte(ObjectInputStream.java:2666)
  |         at java.io.ObjectInputStream.readByte(ObjectInputStream.java:875)
  |         at org.jboss.mq.il.uil2.SocketManager$ReadTask.run(SocketManager.java:290)
  |         at java.lang.Thread.run(Thread.java:595)
  | 
instead of the SocketException. But it seems to make no difference, too. Whether the one or the other exception occurs is undetermined.

I hope that the snippets could help a little. Perhaps there is also another log setting to find a clue on the problem?
