Programming mediations

Several distinct tasks are involved in programming a mediation. Typically, the mediation code is written by a programmer, and is then deployed and administered by an integrator.

Code examples for writing a mediation are provided in the following topic: Add mediation function to handler code. The following application programming interfaces are provided for you to work with messages:

• Use the SIMessage API to manipulate the contents of the message.

• Use the SIMediationSession API to access the service integration bus so that the mediation can send and retrieve messages.

We can deploy mediations by using tooling such as the Rational Application Developer tools.

The tasks for programming a mediation are as follows:

Develop

Writing a mediation by adding functional code to a mediation handler.

Deploy

Add a mediation to a mediation handler list, and deploying it.

Administer

Associating a mediation handler with a destination (optional), and configuring the parameters to be used by the mediation handler at run time.

Take the following steps to program a mediation:

 

1. Create a mediation handler.

   See Writing a mediation handler.

2. Add mediation function code to the mediation handler.

   See Add mediation function to handler code.

3. Working with the message payload, for example for logging messages within a mediation.

   See Working with the message payload.

4. Use the Rational Application Developer tools to create a handler list, add the mediation handler to the list, and deploy the handler list as an Enterprise Archive (EAR file). See the Rational Application Developer information center for information about how to do this.
