I'm new to the JMS and so I'm looking for a free and simple JMS Broker. Is JBossMQ a Broker or is this the implementation of the JMS Client API? Are there some free JMS Broker on the net?
I'm going to be releasing an open source toolkit for EAI soon, called "Proteus", which will include a message broker. The broker will address a variety of sources and sinks, including JMS, native MQSeries, and databases. License will be GPL. I'm still working on the documentation and website but I can shoot you a copy if you email me.
