Hermes JMS is an open source JMS Browser tool ,this works with Weblogic JMS implementations. I have found that this tool is very useful for me to verify view/move/delete JMS messages in queues and topics.
We can download the latest version of Hermes on http://sourceforge.net/project/showfiles.php?group_id=61713
The latest version will support weblogic 10gR3 version and it can be use with oracle application servers also
