java.lang.Object weblogic.application.ApplicationLifecycleListener
The abstract class, ApplicationLifecycleListener, should be extended to create listener, startup and shutdown classes that a user may wish to tie into their application lifecycle.
We currently support four stages of the lifecycle for listener registration: preStart, postStart, preStop, and postStop. In addition, the extended classes can be of three types: listeners, startup classes, shutdown classes. Typically, listners will extend the WLS abstract class, ApplicationLifecycleListener and implement all relevant methods (preStop through postStop) and will fire according to the methods implemented. For example, a fully implemented listener class will fire at all lifecycle events (preStart, postStart, preStop, and postStop). A startup or shutdown class with only implement its main method and fire either at preStart (startup) or postStop (shutdown).
