How to a Write a ESB Flow to consume whenever a new topic is created ?

[ashif2]

I have experience in talend batch processing. I'm new to talend ESB. Can anyone help me to write a flow to copy data from JMS to database whenever a new topic is created in the Integration Layer(possibly Tibco)?

thanks for response @xdshi.

I set up a Tibco EMS Server in my machine, whenever I create a new queue message/topic , it should be consumed by Talend ESB and loaded into Oracle Database..

Topics tend to be hierarchical. I believe Tibco EMS supports that too. Check you Tibco documentation.

If it does the easiest is to subscribe to the root or an intermediate node of the hierarchy instead of a leave.

If you can only subscribe to a topic at a time it gets more involved. You need to write a "script" that

• uses JMX to be notified of the new topic
• convert that topic into a Talend Context Parameter
• instantiate a new route with the additional context parameter subscribing to this new topic

This assumes a 1:1 for topic:route
