Using the ma88 classes I've written a Java application and also a threaded applet to get & put messages.

I read the PDF that comes with ma88 and in particular Chapter 12 on JMS. I don't understand JMS yet and my immediate needs would be met if my humble applet could apply an MQRFH header.

In my code msg_put is an instance of class MQMessage. I wrote the following line.

msg_put.format = MQC.MQFMT_RF_HEADER_1; // Apply 'MQHRF '

However the format still appears blank in the message which is put to queue.
What else do I have to do ? My next step (had the format appeared as 'MQHRF ') would be to create the associated header in the data portion of the message by prepending it to the existing data.

Many thanks in advance

My understanding is that with JMS the RFH header is present unless you specifically state that the destination is a non-JMS application.

See setTargetClient in the Destination class.
JMSC.MQJMS_CLIENT_JMS_COMPLIANT
JMSC.MQJMS_CLIENT_NONJMS_MQ

On the other hand, if you are using base MQ Java rather than JMS, which it looks like you might be, I don't know the answer.
