We have Message Driven Beans listening to the queue.
We have a client which is sending JMS messages to the Queue. It sends 100s of messages one by one. On the server, eight messages are being listened to and processed. The rest are ending up in the pending messages.

Do you have any idea what could be going wrong and why would it not process the rest of the messages. I'm trying to debug using the eclipse, what I found out was, after eight messages, the listener method on the MDB, which is 'onMessage' is not at all called again.

Its very little information I have provided. If you want to know anything, like configuration details or code snippets, please let me know.

how are you handling ACK of the messages? What transactionality handling is set for the MDB?

ACK is AUTOACKNOWLEDGE
Transaction Type is REQUIRED.


This is snippet from the thread dump once the server stopped receiving any messages:

"ExecuteThread: '6' for queue: 'weblogic.kernel.Default'" daemon prio=5 tid=0x28 9b8410 nid=0x634 in Object.wait() [2af1f000..2af1fdb0]at java.lang.Object.wait(Native Method)

been a while since I've worked on Weblogic, but it definitely looks like its waiting on a transaction... unless you are actually doing some transaction related processing in the MDB set the Transaction Type to "NotSupported", otherwise it could be waiting for an XA transaction to be commited somewhere....

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

Thanks a lot. It worked after changing the transaction type to NotSupported. :-)
