BTW.. if your interested in tracing the path a message, you might want to use a BrokerPlugin like:
https://svn.apache.org/repos/asf/activemq/trunk/activemq-core/src/main/java/org/apache/activemq/broker/util/UDPTraceBrokerPlugin.java which will generate UDP messages for each operation on the broker. If someone whips up a nice GUI to interpret the events I'm sure you could get a very nice view of where messages are in your system. On 7/24/07, Rob Davies <[EMAIL PROTECTED]> wrote:
