hi everyone!!!
I 'm studyding websphere IBM queue 6.0.I want to write a example using publish and subcrible model. In My Application , I wants Message from Publisher which throws Broker only can go to one subcribler and another subcrible can't receive this message although they have the same topic with publisher.
I read the book which is "pub- sub user guide" , it said that my program could be build but it didn't show how to built. Who can show me!!!!
thanks a lot
SonHH

The Application Programming Guide. Or any compentant training course.
Your example has 2 parts. The first is the construction of a publisher and subscribers(s), the APG will give you the program structure while the pub/sub guide gives you the formats & commands needed by such messages (along with the queue manager configuration). The second part is the securing of the message which is not a programme fuction but an administrative one. You may find this an interesting challenge as, by default, all matching topics are delivered to all matching subscribers - this is sort of the point! You'll need to develop some strategy to tell the messages apart.
Happy Reading!

Message Broker provides topic level security through the UserNameServer component.
This will allow User A to subscribe to a topic, and prevent User B from doing so.
Message Broker also allows for content-based subscriptions: so user A can subscribe to Topic 1 but only receive messages that, for example, have a price > 100
