The JBoss generic JMS JCA RA uses a JMSProviderLoader for many of its configuration details. The JMSProviderLoader exposes 3 different attributes for a connection factory:

-FactoryRef
-QueueFactoryRef
-TopicFactoryRef

The JCA RA completely ignores the FactoryRef and it uses the QueueFactoryRef or TopicFactoryRef based on if it is connecting to a queue or a topic for which it uses a javax.jms.[XA]QueueConnectionFactory or javax.jms.[XA]TopicConnection factory respectively. There is no support for factories which just implement javax.jms.[XA]ConnectionFactory even though the created connection is eventually cast to a javax.jms.Connection.
