If you look at the JavaDoc for the MQMessage class (http://www-01.ibm.com/support/knowledgecenter/SSFKSJ_8.0.0/com.ibm.mq.javadoc.doc/WMQJavaClasses/com/ibm/mq/MQMessage.html)

it extends the MQMD class (http://www-01.ibm.com/support/knowledgecenter/SSFKSJ_8.0.0/com.ibm.mq.javadoc.doc/WMQJavaClasses/com/ibm/mq/MQMD.html)

and this has all the MQMD values on it.. so this code for example will show you the replyTo & type values

  System.out.println("MsgType="+ rcvMessage.messageType);
  System.out.println("ReplyToQ="+ rcvMessage.replyToQueueName);
  System.out.println("ReplyToQmgr="+ rcvMessage.replyToQueueManagerName);
