Work with mediations

Use a mediation to change the content of a message, or the way in which a message is handled.

For an introduction to using mediations with the service integration bus, see Learn about mediations.

A mediation is an application containing a mediation handler. You associate a mediation with a service integration bus destination, and the mediation acts on messages that pass through the destination. The action taken by a mediation depends upon the specific instructions you give in the mediation handler. For example, we can use a mediation to change the contents of a message, or to choose a particular forward route for a message.

To write a mediation application containing a mediation handler, install it into WebSphere Application Server and associate it with a bus destination...

1. Create the mediation application. For examples of how to do this, see:

   • Writing a routing mediation

   • Writing a mediation that maps between attachment encoding styles

2. Install the mediation application into WebSphere Application Server.

3. Create the associated mediation object in the bus.

   The handler list name is the name you gave to the handler when you defined the handler class as a mediation handler.

4. Mediate the destination. Use the console to access the destination to mediate, then select the mediation from the list of available mediations.
