     The immediate Java problem is that the RMQObjectFactory class does
does not implement the InitialContextFactory interface, so an RMQOF
instance cannot be cast to ICF.

     ... which is no help at all: It's like saying "The reason this man
can't walk is that he has no legs," and not addressing how he lost his
legs nor why the legless man is trying to walk in the first place.

     Although I personally have no experience with RabbitMQ (nor with
anything JNDI, for that matter), it appears to me you should seek
Rabbit advice rather than Java advice.  A quick look around the Web
finds several Rabbit-oriented sites; maybe some of them can help you.
