But it is not what we want all cases

If it's designed for generic JMS integration with ANY JMS provider then it fails on its own requirement with JBM

Sounds like the design is broken. You are forcing us to always be always used as XA, because you use instanceof to tell the XAConnectionFactory and ConnectionFactory apart.

I.e. the JCA implementation currently implicitly assumes that the a particular JMS provider won't use the same class to implement XA and non XA interfaces.

As you yourself mentioned earlier in this thread, another solution which should work with all (read JBM) JMS providers is to add extra field "isXA" in the JMSProviderAdapter config.

Or perhaps something like this - with explicit extra fields:


  |    <mbean code="org.jboss.jms.jndi.JMSProviderLoader"
  |           name="jboss.messaging:service=JMSProviderLoader,name=JMSProvider">
  |       <attribute name="ProviderName">DefaultJMSProvider</attribute>
  |       <attribute name="ProviderAdapterClass">org.jboss.jms.jndi.JNDIProviderAdapter</attribute>
  |       <attribute name="NonXAFactoryRef">java:/NonXAConnectionFactory</attribute>
  |       <attribute name="NonXAQueueFactoryRef">java:/NonXAConnectionFactory</attribute>
  |       <attribute name="NonXATopicFactoryRef">java:/NonXAConnectionFactory</attribute>
  |       <attribute name="XAFactoryRef">java:/XAConnectionFactory</attribute>
  |       <attribute name="XAQueueFactoryRef">java:/XAConnectionFactory</attribute>
  |       <attribute name="XATopicFactoryRef">java:/XAConnectionFactory</attribute>
  |    </mbean>
