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 Learning about mediations.

A mediation is an application containing a mediation handler. We 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 WAS and associate it with a bus destination:

Tasks

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 WAS.
3. Create the associated mediation object in the bus.

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

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