JCAActivator looks for the ResourceAdapter from JBoss ResourceAdapterRepository, so the RAR must have been deployed before the SwitchYard application which has JCA binding. Just adding jboss-deployment-structure.xml with a dependency on the RAR should solve the problem, except HornetQ. The problem here is, since HornetQ RAR deployment is embedded into JBoss subsystem, just adding a dependency on org.hornetq.ra with jboss-deployment-structure.xml doesn't work. We need to investigate how we can hook the HornetQ RAR deployment event.
