Changing JMS Transport message headers and properties at runtime

When sending a message to JMS queue or topic through a business service, default values for several JMS Transport message headers are used. The message headers as well as the message properties can be overwritten by using a Transport Header action in a proxy service when routing to the business service.

We will use it to both define the priority of the message by setting the JMSPriority header and to pass a user-defined property myProperty with the value red.

Getting ready

For this recipe, we will use the solution of the recipe Sending a message to a JMS queue and extend it with a simple pass-through proxy service and then add a Transport Header action.

You can import the base OSB project containing the solution from this previous recipe into Eclipse from \getting-ready\chapter-3\changing-jms-transport-headers-properties.

How to do it...

First we will add the pass-through proxy service which routes the message to the JMSProducer...
