Hi,
I have a JMS consumer that consumes messages send by JMS or non-JMS producers. Is it possible to detect from where the message originated from after consuming it? Reading the MQ JMS manual, it says that JMS_IBM_Format field will contain MQFMT_RFH2 value if the message is from a JMS producer otherwise it would be MQFMT_STRING or blank. But the problem I am facing is that this field appears blank even though message can from a JMS producer. I would appreciate any help on this matter.
Thanks,
Juzer. |

Check out the using java manual and the mapping from RFH2 and MQMD.
You need to find a mapping that is populated from the RFH2 and that is not present on the MQMD. This is the attribute you can check to determine the type of the producer
Hope it helps some

WebSphere MQ messages are composed of three components:
1 The WebSphere MQ Message Descriptor (MQMD)
2 A WebSphere MQ MQRFH2 header
3 The message body.
The MQRFH2 is optional, and its inclusion in an outgoing message is governed by a flag in the JMS Destination class. You can set this flag using the WebSphere MQ JMS administration tool. Because the MQRFH2 carries JMS-specific information, always include it in the message when the sender knows that the receiving destination is a JMS application. |

Why do you care where it came from anyway?
