What you're describing is JMS where a JMS destination serves as the
meeting point. But I think your point is that ActiveMQ is technically
not a component plugged into the NMR using the JBI APIs. OTOH, maybe
what you're seeking is the WS-Notification service engine. But like I
said earlier, the WS-Notification implementation is built on top of
JMS.
I don't feel that a JMS service engine is needed because ActiveMQ is
already being run inside the same JVM as ServiceMix. Also, the
Normalized Message Router makes use of ActiveMQ to send/receive
messages to/from JBI components plugged into the NMR.
