It is working fine for small messages, but is giving following exception when message size is large while putting the message in queue javax.jms.JMSException: Failed to route Reference[-1363948824515837952]:RELIABLE to xyzQueue if i use ClusteredXAConnectionFactory insted of JmsXA then the same message is processed successfully.
