Thanks! So it sounds like I can browse the queue, find matching messages, and then use the delete-by-ID call? Can I get the ID from a JMS message, or do I need to be at the AMQ API level for that?

Please use caution responding, opening attachments or clicking embedded links. *** If you want to remove messages from a queue via the management API there are a couple of methods you can use: - removeMessage[1]: this method takes a messageID which allows you to remove a specific message (assuming you know its ID) - removeMessages[2]: this method takes a filter [3] which allows you to remove any message which matches the filter; if you pass an empty/null filter then *all* the messages will be removed The main thing to keep in mind with filters is that they operate on message headers and properties only. They don't operate on the *content* of the message. The only exception to this is if you're using an XPath filter [4], but that requires your message to be XML formatted text.

I would like to remove one or more matching messages from a queue. But I can’t quite see how to do that. The “matching” requires deserialization of the message to examine its contents. It doesn’t need to be fast.
