Open-Source Applications using Java JMS?

Does anyone know of open-source applications that are built on top of Java JMS? I am looking to find ap开发者_JAVA技巧plications so I can study them and see how they are used.

This earlier post has examples of hypothetical uses for JMS, but I am looking for actual code!

Thanks, Nels

Apache CXF supports JMS as a transport for SOAP messages. Lots of source code to read.

Are you just looking to learn the JMS API? If so, it is actually one of the simplest parts of Java EE so you shouldn't have a problem finding more specific help here.

To answer your question more specifically, have you looked at Apache ActiveMQ or JBoss Messaging? Both are open source JMS providers and they have a lot of API examples and documentation on their sites.
