If you definitely want to speak with a different broker, then I
believe that's exactly what you must do. Each JCA resource adapter is
designed to communicate with only one enterprise information system.

I have zero detail on the design of your system, but have you
considered just letting the applications communicate with a single
broker and then just network two brokers together? ActiveMQ supports
what is known as a network of brokers, i.e., multiple brokers working
together in a federated manner. See the following page for more info:

http://activemq.apache.org/networks-of-brokers.html

A network of brokers forwards messages between the brokers the brokers
based on configuration and demand for messages. This results in what
some folks call distributed destinations.
