Message bean listening to Queue and Topic

[cuthbe]

All i have a MDB which is listening to a Queue but i want to be able to take each message that comes into the Queue do some processing on it and then publish it to a Topic, Then Listen on that Topic for any message replys. Is there such an example on this.

Would it be better to deploy two MDB's one for the Queue and processing and one for the Topic ?

Hello,

On the MDB you have, write an onMessage function, which will be executed when a new message comes at the Queue. You can process the message and then publish to the Topic from the same function. Then, you can write another MDB which listens on the Topic with the onMessage function, so that you can process messages, that arrives on the Topic.

So basically the best method is to create two MDB one for process on the queue and one for process on the topic, and then replying to topic events.

Is there any group documentation on setting up oracle DS so that i can send messages to a database.

And when posting messages to the Topic should this be done in a new Thread ?

You can find the Configuration details for setting up Oracle DS for sending messages in the following wiki page.
