Mediation modules are Service Component Architecture (SCA) modules that can change the format, content or target of service requests.
Mediation modules operate on messages that are in flight between service requesters and service providers. They allow you to route messages to different service providers. They also let you transform messages: you can amend message content or form. In addition, mediation modules can provide functions such as message logging, and error processing that is tailored to your requirements.
You can change certain aspects of mediation modules dynamically, from the WebSphere Process Server administrative console, without having to redeploy the module.
Mediation modules are created using WebSphere Integration Developer, and are generally deployed to WebSphere Process Server inside an EAR (enterprise archive) file.
You can export a mediation module from WebSphere Integration Developer, and cause WebSphere Integration Developer to package the mediation module inside a JAR (Java archive) file, and the JAR file inside an EAR file. You can then deploy the EAR file, by installing a new application from the administrative console.
Mediation modules can be thought of as one entity. However, SCA modules are defined by a number of XML files stored in a JAR file.
