Hi,
We have a flow that sends a message including an RFH2 header to a queue.
Then we have a Java module that picks up the message from that queue using JMS. The problem we experience is that the JMS class fails to parse the RFH2 header. The class crashes when we try to open it. We have tried both "MQRFH2" and "MQSTR" in the MQMD.FORMAT field. The result is the same.
Is there anyone that can help us with this one?
We are using WMQI 2.1, CSDE 0.2 on an NT-machine. We are using Websphere MQ 5.3.
Regards Kjell |

Hi,
If you want to suppress the RFH2 header in output message. Do the following things in the message flow.
1. If you have selected copy message headers button in compute node then de-select it. (You should have both buttons in compute de-selected)
2. Use the following code to copy headers
SET OutputRoot.MQMD = InputRoot.MQMD;
SET OutputRoot.Properties = InputRoot.Properties;
SET OutputRoot.MQMD.Format = 'MQSTR';
This has worked for me so I think it should work for you as well.
Thanks

It's actually MQHRF2. That's why it's always better to use the defined constants, MQFMT_RF_HEADER_2.
Now, is the RFH2 header coming in to the flow, or are you building it.
If it's coming in, then you shouldn't have to change anything in either the MQMD or the RFH2. It should just flow through.
If you have to change any of the attributes in the RFH2, then remember the specification of the Field is slightly differerent than normal:
SET OutputRoot.MQRFH2.(MQRFH2.Field)Format = MQFMT_STRING;
Lastly, if you have an RFH2 coming in, and you don't want it in the output, then:
SET OutputRoot.MQRFH2 = NULL;
Cheers,
