Hi,
I am new on this subject, have a project deadline coming and I can't find a solution for this problem.

Originally I had this code, it worked fine....

MQMessage sendMessage = new MQMessage() ;
MQPutMessageOptions pmo = new MQPutMessageOptions() ;

pmo.options = MQC.MQPMO_SET_IDENTITY_CONTEXT | MQC.MQPMO_FAIL_IF_QUIESCING ;
sendMessage.replyToQueueName = replyQueueNameMem ;
sendMessage.replyToQueueManagerName = queueManagerNameMem ;
sendMessage.format = MQC.MQFMT_STRING ;
sendMessage.expiry = 6000 ; // never expire
sendMessage.persistence = MQC.MQPER_NOT_PERSISTENT ;
sendMessage.messageId = MQC.MQMI_NONE ;
sendMessage.correlationId = pCorrId; // where pCorrId is the

//try-catch removed

sendMessage.writeString(InArg) ;

then, we changed to JMS. now, I can't get the right mapping on the Reply Queue! I am reading from a .bindings file but even as I change the value there and I see it in the 'watches' of my IDE, when it's posted on the queue it is different!
I am using the following options for the reply_q:

q_Reply.setPersistence(JMSC.MQJMS_PER_PER);//persistence
q_Reply.setPriority(1); //1
q_Reply.setExpiry(0); //unlimited
q_Reply.setTargetClient(1);//MQ target
q_Reply.setCCSID(546);

and the following options to send it

QueueConnection conn = qcf.createQueueConnection();
QueueSession session = conn.createQueueSession(false, Session.AUTO_ACKNOWLEDGE);

QueueSender queueSender = session.createSender(reply_q);
queueSender.setDeliveryMode(DeliveryMode.NON_PERSISTENT);
queueSender.setPriority(1);

TextMessage outMessage = session.createTextMessage(SMBJMSMessage.getData());
outMessage.setJMSMessageID("");
outMessage.setJMSCorrelationIDAsBytes(msg.getJMSMessageID().getBytes());//where msg is the original request
queueSender.send(outMessage);

Apart from the different mapping, one annoying thing is as you see I am setting the message body but when I see the queue it has the content : "RFH "

Any help, suggestion, orientation or comment will be greatly appreciatted...

Thanks
