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.

Before you begin

Code examples for writing a mediation are provided in the following topic: Adding mediation function to handler code.

The following application programming interfaces are provided for you to work with messages:
  • You can use the SIMessage API to manipulate the contents of the message.
  • You can use the SIMediationSession API to access the service integration bus so that your mediation can send and retrieve messages.
You can deploy mediations by using tooling such as the Rational® Application Developer tools.

About this task

The tasks for programming a mediation are as follows:

Developing
Writing a mediation by adding functional code to a mediation handler.
Deploying
Adding a mediation to a mediation handler list, and deploying it.
Administering
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:

Procedure

  1. Create a mediation handler.
  2. Add mediation function code to your mediation handler.
  3. Optional: Working with the message payload, for example for logging messages within a mediation. For more information, see Working with the message payload.
  4. Use the Rational Application Developer tools to create a handler list, add your 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.
