Can the message published in the single topic,will be retrived by multiple subscribers using the content of the message.
I want to send the same message(publishing in single topic) in the different format for the multiple subscribers.I know this is available in MQSI using the subscription point.Can the same function will be implemented in MQ java base classes and JMS. |

i too had similar question early on.i dont think thats possible because only MQSI can parse the messages and make sense out of them.Hope i am right.  |

| If you want to do some kind of message reformatting for various publishers, your going to be using WMQI to get it done since it is what will do the reformatting. |

Hi all ,
Even though,if we go for MQSI.I know we can reformat the message and publish it into different subscribtion point.
But,Can the simple MQ subscribers written in any language will get the messages using the subscribtion point or else all the subscribers needs the MQSI ?

I'm not 100% sure that I understand your last comment. In order for any subscribers in MQ to get messages, they have to work through a broker. This can be the MA0C SupportPac or any of the WMQI products. The MQSeries qmgr by itself doesn't handle the pub/sub. Is this what you are asking?
edited for clarification...Programs will use the regular MQ APIs to get their subscriptions. They won't actually work through the broker. The broker will take the publications and put messages on the subscriber queues.

I think it is mater of design issue. Utilizing MQSI in every possible is good, but there is some performance issues related to that also.
If you can do it in JAVA before sending it out so that MQSI does not have to do anything is good too. It really depends upon your design requirements.
