Hi,
I put a message on an MQSeries (v5.3) queue using a java client application. I have a listner MDB running on WAS which picks up the message and inside this MDB I want to lookup a user defined property. This is what I plan on doing inside the MDB txtMsg.getStringProperty("SpecialProp")
How do I set this up in my java client which is dealing with raw MQ. Essentially, I want to know how to map MQ message to a JMS message so I can create new property fields. |

It will be easiest, if you want to get using JMS, if you also put using JMS. Is this a possibility?
A "raw" MQ message can't have user-defined properties, unless you define the binary format yourself. The way MQ's JMS does this is by encoding in text using an XML-like format, and placing this in the "raw" MQ message. The MQ JMS classes in putter and getter apps have all this built in. |

Well, a little more technically, the MQ JMS API uses the MQRFH2 header in a very well documented manner, and includes 'folders' in that header that end up containing the properties.
And it will be a significantly large project to build a proper JMS header yourself. So as mvic says... Use JMS.
Or don't use JMS Properties.
