Possible to use a message bridge for access to message copies?

Question

I'd like to be able to consume copies of messages that go across a queue so that they can be validated during testing.
I've been unable to find any mechanisms for authenticated message monitoring which exists in other JMS brokers such as TIBCO EMS and so I'm going down the route of seeing whether a message bridge could help me. My thinking is that I can bridge from QueueA onto TopicA - where the message stays on QueueA and a copy is sent to Topic A which can be safely consumed by the testing tool
First question - is this a workable solution, ie does the message sent to QueueA stay on QueueA until is is consumed normally, or is the message forwarded to the bridged TopicA thus removing the original message?
Second question - I've tried to get a bridge working but encounter an error when trying to use it. The monitoring tab shows the bridge is up OK but I get the exception below in the admin console
<11-Oct-2010 13:55:12 o'clock BST> <Warning> <MessagingBridge> <BEA-200026> <Bridge "Bridge-0" encountered some problems in one of its adapters or underlying systems. It stopped transferring messages and will try to reconnect to the adapters shortly. (The exception caught was javax.resource.ResourceException: Error sending message.)>
Any help and advice appreciated

Answer 1

One approach is to use a topic; producers send to the topic and both of your application consumer and your auditing consumer consume from the topic. If you have multiple application consumers, you could have a bridge to forward the messages from the topic to a queue and your applications consumers can consume from the queue, while your auditing consumer consumes from the topic.
There is a message life cycle logging capability in WLS JMS, which may be helpful. It can be enabled on a per destination basis. It logs an event in a file when a message is produced, consumed, removed, expired and etc. However the message body is not available in the log. The details can be found at
