Present Scenario: C++ application puts messages on Mainframe MQ v5.3 and CICS app is receiving with no issues.
Requirement: Java app has to send to same mainframe queue and same CICS application should process the messages.
CICS is not updating the messages (from Java) in their tables where as C++ data is reflecting in tables.
I found the difference in format name when i compared message put by C++ and Java:
C++: MQCICS
Java: MQHRF2
What changes has to be made in application so that we get MQCICS as format name? |

Add the CICS header to the Java message. Just updating the format string isn't enough by itself.... 
Seriously, the format string only describes the section that follows, so for Java it's indicating that the next section is an RFH2 header. If you look in the RFH2, you'll see that the format shown there describes the message format (typically string).
If you look in the C++ message you'll see the next section is the CICS header and the format shown there either indicates an RFH2 (if present) or the message format.

I'm helping out an application guy who doesn't have much experience in sending messages to Mainframe Queue. It would be great if you can help how to add CICS header in message?
Thank You. |

As you're new to the forum, you don't know that I'm the last person to ask about Java coding issues! 
The CICS header is documented in the Application Programming Reference, which is in the product InfoCenter (link at the top of this page). That should give you some insights until a qualified Java poster responds.

If you are posting the message using JMS you need to read the specifics for CICS. I believe you need to use a MapMessage.
You probably should also set the destination JNDI for targetClient to MQ (suppressing the RFH header)
Have fun
