Hi,
I am waving in a difficult state now-a-days that not able to get the solution of the following problem.
I am using MQ Pub/sub -broker (Not WebSphere Business Integration Event Broker and WebSphere Business Integration Message Broker) in my application.
I have one topic and multiple subscriber i.e queues which are interned get listened by individual MDB. My problem is, based on the topic's message-header Id, I need to pass message to different Queues. Actually I want to use the content/header based filtration on the message thru broker to send message to different queues accordingly.
Is there any way to do it? Make sure that I don't want to use MQI or MQIEB or WBIMB etc. I just want to access the control of the broker which comes with WebSphere MQ V5.3 support pac MA0C (WebSphere MQ (MQSeries) - Publish/Subscribe). I am using IBM MQ standard code base mqjmspub.java and mqjmssub.java for this purpose.
It will be really helpful to me, if you have any clue or solution for this.
Thanks in advance.
Sanks
Supporting publish/subscribe
Other IBM products, including , support publish/subscribe implemented not only with WebSphere MQ, but also with other implementations, such as IP multicast. Those products are beyond the scope of this article. |

One solution is to use JMS message selector API.
But I don't want to use that. It will put impact on my existing system code base. I just want to do that by means of configuring the MQ pub/sub.
Is there any way to facilitate MQ pub/sub configuration to do the same?
Can any body put light on it? |

You can't do content filtering with the plain MQ Pub/Sub broker. This is one of the value-added features of the Event Broker (which also forms the Pub/Sub engine of Message Broker).
The only thing you can do to change what queue a message gets sent to with the regular MQ Pub/Sub broker is to change the topic you publish the message on.
I don't see why you are trying to use the message ID as anything other than a unique id for the system - but you should look instead at creating a real topic hierarchy, that allows you to publish your messages to the right subscribers.
Or build a single subscriber that then acts as a filter/router that will put messages where they need to go.
