I'm using Talend route and the cJMS component to push and pull message from the ActiveMQ topic.
I need to retrieve the message on the basis of some property so that message can be differentiated for the multiple consumers of the topic. How and Where can I set this property so that while pulling the message from MQ I can use it?
I've tried the URI properties in the "advance settings" of cJMS component but still it is picking all the messages.
How can I achieve this? Let me know if I can provide any other information.

Thanks for your response rchinta_talend.
I'm really new to this and as per my understanding I need to add the header first and then use that header as my selector. I tried changing the flow, please check the screenshot.
I tried understanding the documentation, but i didn't get any source to write the below expression.
selector = header_FIELDNAME header_FIELDVALUE_using_sql_expresssion.
If it's not too much to ask, an example for the same would work for the me.
I'm still confused,
should I add the header and use it as selector in advance properties of consumer JMS?
or should I add the properties in advance options of publisher JMS and same properties in consumer JMS?
or should I not add the header at all?
How can I use the selector to filter?
In my publisher route I used the cSetHeader to add a header with my message ("Header", "MyHeader" ).
In my subscriber route, in the advance properties of cJMS component i added a selector like following
"selector" ,"Header = 'MyHeader'".
Using this I'm able to pick messages selectively from the Topic.
Thanks for your help, rchinta_talend!!
