Hi Forum,

I am confused with Header part of message.

I am publishing messages to queue like this :

Code:


private Session session;
   
private MessageProducer producer;
....   

TextMessage ackMsg = session.createTextMessage();
ackMsg.setText("Some XML");         
producer.send(ackMsg);



Do I need to worry about header?means do I have to explicitly set header or JMS api will take care of it?
will the application receiving this message will get message with header?


thanks in advance.

If you're using the JMS libraries, the message will contain the JMS header. If you're using the native Java API it won't. Check the Java manuals for how this is expressed in the WMQ world. Also look up TARGCLIENT.

How the receiving application handles it is a coding issue. There's no reason why a non-Java application can't process a message sent with a JMS header.

My app is running outside of WebSphere Application Server,while the app getting my messages is MDB running in WS app server.

So in instance of my destination, i did this :

producer.setTargetClient(JMSC.MQJMS_CLIENT_JMS_COMPLIANT );

So, I hope JMS lib will take care of header.

thanks for reply.
