If xa-transaction is specified the ConnectionManager implementation i.e org.jboss.resource.connectionmanager.TxConnectionManager::createConnectionListerner(..) will get the XAResource from the MC::getXAResource
 
Here is the code
 
 public ConnectionListener createConnectionListener(ManagedConnection mc, Object context)
      throws ResourceException
   {
      XAResource xaResource = null;
      
      if (localTransactions)
      {
         xaResource = new LocalXAResource(log);
         if (xaResourceTimeout != 0)
            log.debug("XAResource transaction timeout cannot be set for local transactions: " + getJndiName());
      }
      else
      {
         xaResource = JcaXAResourceWrapperFactory.getResourceWrapper(mc.getXAResource(), isSameRMOverrideValue);
         
         if (xaResourceTimeout != 0)
         {
            try
            {
               if (xaResource.setTransactionTimeout(xaResourceTimeout) == false)
                  log.debug("XAResource does not support transaction timeout configuration: " + getJndiName());
            }
            catch (XAException e)
            {
               throw new JBossResourceException("Unable to set XAResource transaction timeout: " + getJndiName(), e);
            }
         }
      }
 
      ConnectionListener cli = new TxConnectionEventListener(mc, poolingStrategy, context, log, xaResource);
      mc.addConnectionEventListener(cli);
      return cli;
   }
 

 
 
The ConnectionListener/ConnectionManager creates the XASession and non XASession, you will have to implement the getXAResource and getLocalTransaction appropriately.
 
The JCA CM will call these methods approprately during the execution.
You can find more from JCA specs CM chapter.
 
HTH !
