A mediation handler is a Java program that performs the function
of a mediation, and can be deployed in a mediation handler list.
Mediation handlers are the components of mediation handler lists. Each
mediation handler executes some specific message processing at run-time, for
example:
- Transforming a message from one format into another.
- Routing messages to one or more target destinations that were not specified
by the sending application.
- Augmenting messages by adding data from a data source.
The mediation handler class implements the interface
com.ibm.websphere.sib.mediation.handler.MediationHandler.
A mediation handler can have properties that control its behavior.
A mediation handler is packaged for deployment with a supplied Enterprise
Java Bean (EJB). At deployment, you can set properties to control the behavior
of the mediation at run-time, and specify membership of one or more mediation
handler lists. You deploy a mediation handler as an EAR file using the Deploy
wizard in the Application Server Toolkit, and install it into WebSphere Application
Server.
