Hi
I am trying send messages through MQ to external Mainframe systems. The specification those Mainframe guys have told me is just that I need to send the messages in EBCDIC format  Now how do I manage to do this from my Java program!
Is there any way I can specify it as a part of Queue/ Channel property? Kindly reply asap. Thanks a ton in advance.
Thanks and Regards

You need to tell the mainframe guys to set MQGMO_CONVERT in their program.
And you need to ensure that you either use a TextMessage if you are writing JMS or that you set Format to MQFMT_STRING if you are using the Java API.

Thanks a lot for the info Jeff.
Is there any way of handling the same through MQ Properties? I mean setitng some property values in the Queue Manager or Channel? If the above is the only way, then kindly pardon my ignorance on the same.
Thanks and Regards,

You can instruct the channel to convert the message.
You don't want to do this, though. It is not recommended.
And you will still have to ensure that your message is either a TextMessage or has MQFMT_STRING Format.

Thanks a ton again Jeff.
If you could let me know how to instruct the Channel to do that, it would be extremely helpful. Kindly help me out.

Your MQ admin will know how to do it, and should hopefully recomend against it when you ask.

One thing you can do in JMS is play around with the Q definition:
| Code: |
String myqstr = "queue:///myremoteq?targetClient=1&CCSID=500";
Queue thequeue = Session.createQueue(myqstr); |
This is from memory so you might want to read up on the using java manual.
The CCSID or targetClient can as well be set through the JNDI layer.
Enjoy
