Hi,
I found a way to loop through the DLQ.
Just change the below constant
private const string QUEUE_NAME= “test.queue”;

private const string QUEUE_NAME= “ActiveMQ.DLQ”;

This is really great stuff and Easy to understand.

Hi,
This code is working very well for me. Thanks for the sample.
I would like to read the DLQ and reprocess the Message. Is there any sample .net code available for this?

Thanks
Murali

I have written a Windows Service using code very similar to what is posted above. Occasionally, I receive messages in a different sequence than they were put on the queue. Is this expected behavior for the MessageListner? Should I rewrite to use consumer.receive instead?

Thanks

Adam, I'd suggest having a look at this article as a starting point. It's not something I've looked into in any detail.

Great Article!

Do you know if there are any plans with incorporating XA Transactions with NMS?

Thanks.

I ma trying to put this into a Windows Service. My main thread looks like this:

private void ThreadRun(){
using (QueueConnection connection = factory.CreateTransactedConnection(ConsumerQueue))
{
using (QueueListener listener = connection.CreateQueueListener(new MessageProcessor(traceLogging, ServiceName, ConnectString, emailProps)))
{
while (threadrun)
{
Thread.Sleep(interval); //interval = 1000
}
}
}
}

The while loop just spins to keep the thread and the listener alive.

Once in a while, I will start the service with messages waiting on the queue but they do not get processed by my service. No errors are logged it just acts like they are not there,

1. Is my ThreadRun method the best way to keep the listener alive and..

2. Has anyone come across the problem I describe where messages are not seen?

Thans for the great article – it helped me a lot.
I am trying to make message groups working with AMQ 5.0.0 and NMS.
I don’t see easy way to configure it via classes. I tried add exclusive=true on destination url but consumer doesn’t get messages in order.
I’ll appreciate any tips
