A custom service provides the ability to plug into a WebSphere Application Server application server to define a hook point that runs when the server starts and shuts down.
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.
When an application server starts, any custom services defined for the application server are loaded and the server runtime calls their initialize methods.
