0.15: What are custom services?

A custom service provides the ability to plug into a WebSphere application server, to define an hook point to be executed at server startup and shutdown.

A developer implements a custom service containing a class that implements a particular interface. The administrator configures the custom service in the administrative console, identifying the class created by the developer. During application server startup, any custom services defined for the application server will be loaded and have their initialize methods called by the server runtime.
