Artemis: Enumerating messages without consuming them
In Artemis, using the management API (ClientRequestor, ManagementHelper), is there a way to browse the contents of a queue without consuming the messages?
We need more than just the count, we actually need to examine each message.
Thanks
John

Yes, you could definitely use a JMS QueueBrowser. I didn't mention it because you were already using the core API. If you used the core JMS client then the QueueBrowser implementation would use the core API's browse-only consumer under the covers. The advantage with using JMS is that it's an API and you can swap out implementations if you ever need/want to (e.g. if you switched brokers). The disadvantage is that it adds more dependencies to your code (although that might not be significant for your use-case).

I also see that I could use a JMS QueueBrowser. Is there an advantage to one over the other?

It is possible to browse the messages of a queue using the management API. This is what the web console does when it displays the messages in a queue. However, if you're using the core API then the most straight-forward way to browse messages on a queue is with a browse-only consumer (e.g. using o.a.a.a.a.c.c.ClientSession#createConsumer(SimpleString, boolean) [1]).
