Correct. Basically you need a MDB that listens to your queue/topic and calls the jBPM service.  I've seen this scenario multiple times out in the wild. jBPM is 'just a jar' and as such we don't ship it with JMS listeners etc.

Is this possible, or would I have to launch all of the required workflows from my service, which would mean knowing which workflows need to be executed. 

Unfortunately, there is no such thing currently in JPDL. I know that it a use case which tends to pop up sometimes - and it is also defined in BPMN2 spec... so my current approach would be to attach in some way or the other metadata (perhaps using the process definition key - prefixes or something) to the process definitions, which is used when such an event is received.
