This topic is an overview of the tasks 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 at Adding mediation function to handler code.
The following application programming interfaces
are provided for you to work with messages:
- SIMessage API allows you to manipulate the contents of the message.
- SIMediationSession API provides access to the service integration bus so
that your mediation can send and retrieve messages.
Mediations are deployed using the Application Server Toolkit (AST).
Why and when to perform this task
The tasks for programming a mediation are:
- 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 runtime.
Take the following steps to program a mediation:
Steps for this task
- Create a mediation handler. For more information, see Writing a mediation handler.
Add mediation function code to your mediation
handler. For more information, see Adding mediation function to handler code.
- Working with the message
payload, for example for logging messages within a mediation. For more information,
see Working with the message payload.
- Use the Application Server Toolkit (AST) deployment wizard 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 AST information center
for information about how to do this.
