OSB JMS Message Selector / Filter

Question

HTTP PS and JMS BS puts messages on WLS JMS Queue. We need consume some messages from the Queue based on payload content since interfaces for other messages may go Live in next year.
JMS Message look like
<Schools>
<School>
<Id></Id>
<ServiceArea>100</ServiceArea>
<Type></Type>
</School>
</Schools>
We need to consume messages where ServiceArea = 100.
Can you advise how to consume messages where ServiceArea = 100 ?
I would appreciate your help.
Thanks in advance.

Answer 1

JMS message selector on message payload fields is not recommended and it will have performance implications. Instead you can design this in either of the 2 ways below
1 - Modify the HTTP PS which publishes the message to set the JMSCorrerlationID header ( or any othe custom JMS property) with the value of Service Area. You can achieve this using Transport Header action in HTTP PS route node.
For the JMS consumer proxy set a message selector on the JMS transport page to filter only messages belonging to this service area.
2. Let the HTTP PS continue publishing all messages to the output queue. Have a new component in your design called a 'disaptcher' which reads all the message from the output queue, check service area tag and route messages belonging to particular area to an area specific queue. Have your jms consumer specific for service area 100 to listen to only this Area specific queue.
