I (or the writer of the document I'm reading) made af "Response" class called "InsuranceResponse". The response class is sent to the Camel Routebuilder. I would like to swith on either the classname of the object I'm sending or a field, e.g. "CompanyName", in the object. I create/send like this: ObjectMessage insuranceMessage = session.createObjectMessage(); InsuranceResponse response = new InsuranceResponse(); response.setRequestID("1"); response.setInsuranceCompanyName("Luxury Cars"); response.setPrice(100f); response.setResponseID(UUID.randomUUID().toString()); insuranceMessage.setObject(response); producer.send(insuranceMessage); Then I receive like this ("responseMessage" returns null all the time, but I guess it's beacuse my Camel Routebuilder isn't wotking, so no object is send to the queue): ObjectMessage responseMessage = (ObjectMessage) consumer.receive(); InsuranceResponse insuranceMessageReceived = (InsuranceResponse) responseMessage.getObject(); >>You can also use Camel to set a header like so >>from("seda:a").setHeader("foo", constant("bar"))... Cool. But what is the corresponding function in Eclipse/JMS to the "setHeader"?!
