Does JMQ provide message persistence?

I would like to know if JMQ provides persistence i.e. what if I have messages queued up and the JVM goes down or server shuts down?

JMQ's persistence works as specified in the JMS spec. The messages aremaintained by the JMQ router. If the router crashes the persistent messageswill still be there when the router is restarted. If the messages werenot persistent then they will be lost.
