It sounds like you are using JMS to put a message and you have your targclient property set to JMS. Try setting it to MQ and you won't get the header in the first place.
If this doesn't make any sense, check out the table in the Using JMSAdmin section of the Using Java manual or post back. |

| Alternatively use JMS instead of base java and the header will be removed automatically |

Hi Thanks for the replys.
I am new to this and only have the base MQ sample programs to use so if anyone can point to the same examples for JMS then that would be good. However I have no choice to set the client type on the message this is done by the application. I have to retrieve the messages from one queue and add to another but because the messages were added by a JMS app and I am using the base MQ API I am unable to find any method to remove the header.
How do I set target client to MQ when retrieving a message with a JMS header using base java? I can then add the message back to the second queue in MQ format
Thanks |

These should have been installed, as long as you did a Custom install and selected Java.

This sounds like you are acting as a "middle man" here, just to strip off the RFH2. Why can't the receiving application do it. Or write this in JMS.

That option is only for the application that PUTs the message.
If you are using the normal API set, or non-JMS Java, then the RFH2 header comes in as part of the payload. It would be easy enough to check the Format of the incoming message, and if it's an RFH2, then one of the fields in the RFH2 gives the total length of the header. Just skip that part, and PUT what's left. You will have to "move" a couple of fields from the RFH2 header back to the MQMD, like the Format, to ensure it's still described correctly.
Cheers,

| You can only set the TargetClient property for WebSphere MQ JMS resources. If you are running with the embedded JMS, then it is expected that you are communicating with other JMS applications and the default is to have it set. |

Yeah known problem. Go into the corresponding xml resource file and change "JMS" to "MQ" on the corresponding queue attribute, save and reboot the server. Now it should stick.
Had the same problem a while back....
Enjoy  |
