Dennis,
Not being a JMS coder, I can't help but ask the following.
So, JMS performs the get with Correlid on the MD. Then after
matching, JMS adds the RFH2? Could the JMS coders be performing the
get improperly? Is it necessary to tell JMS, somehow, to look in the
MD for the Correlid?
Or do we need to have a JMS program that just does a JMS get followed
by a put (to get the JMS RFH2 built). Then have the program which
matches on the Correlid execute against the message with the JMS RFH2.
Currently I am sending to JMS a message with the Correlid in the MD
and No RFH2 Header. The JMS guys just can't seem to match the
Correlid from the MD. And I'm really struggling trying to help them
out since I don't know JMS.
Thanks so much for your help.

If the messages are going from from a non-JMS application to a JMS
application, somewhere along the way an RFH2 header needs to be
constructed. Trying to do it in the sending application or in MQIS is
the hard way. Just send a message without the RFH2 header and the JMS
receiver will do it automatically by pulling appropriate info out of the
MD.
Probably the reason JMS is having difficulty without a JMS header on the
inbound message is because of the way JMS transforms msgid and correlid
with an "ID:" prefix when it builds the RFH2 header. It may take som
futzing to figure out exactly how to get JMS to match on correlid, but
you definitely don't need an RFH2 header to do it.

Subject: MQSI 2.1 RFH2 Header for JMS - Help
Hello,
I am working with some JMS Developers on a Request Reply Application.
This application sends a request thru mqsi (where conversion from xml to
copybook occurs) to the mainframe. The mainframe sends the reply back
to mqsi (where copybook to xml conversion occurs) and on to JMS where
JMS matches on Correlid. I have verified that the Correlid is making
the round trip.
Unfortunately, JMS can't seem to pull the message off the Q without
there being an RFH2 Header with jms.Cid equaling the Correlid.
Now that JMS is pulling the message off of the Q, it bombs. Apparently,
JMS is looking for a text message, but since the RFH2 Header exists, it
considers the entire message to be in Byte Format.
Being an MQ person, I am interpreting for our JMS Developers. Did
something get missed in MQSI? Would someone be willing to share some
MQSI code that builds the RFH2 Header for jms? Any thoughts and
directions would be greatly appreciated.
Thanks once again for any help.
Joe
