Question

Is there any option to set a routing key at message level in Apache Qpid.
The way I currently do is

1. Specify routing key in address string. Create a producer with this destination address.

   topic = (Topic) context.lookup(“destination”);
   sender = session.createProducer(topic);

2. Send messages through the producer.

This way all the messages have the same routing key. What I want to achieve is set a routing key for each message individually.

Let me know if this can be done

Answer 1

This can be easily done by specifying a per message subject.
The “subject” as defined by the Qpid address scheme, would map to the routing key for Topics when using the 0-10 protocol.

Message m = ssn.createMessage();
m.setStringProperty("qpid.subject", "my-subject");
prod.send(m);

This allows you to use standard JMS interfacing while still using the Qpid add-ons.
