ApplicationEvent

public class ApplicationEvent extends Object
ApplicationEvents are sent before/after an application is loaded/unloaded. Listeners that are interested in getting ApplicationLaoderEvents can register with the ApplicationLoaderEventNotifier as follows: ApplicationLoaderEventNotifier notifier = ApplicationLoaderEventNotifier.getInstance(); notifier.addListener(listener); Application events are sent even when StandaloneModules are deployed / undeployed. ApplicationEvent.getApplication().isVirtual() will return true for stand-alone modules and false otherwise. Generally, APPLICATION events are sent in the following order a) BEFORE_APPLICATION_LOADED b) AFTER_APPLICATION_LOADED c) BEFORE_APPLICATION_UNLOADED d) AFTER_APPLICATION_UNLOADED Note:- There are some cases, when AFTER_APPLICATION_LOADED and BEFORE_APPLICATION_UNLOAD will not be sent to listeners. In particular, if an Ejb cannot be loaded successfully then no AFTER_APPLICATION_LOADED and BEFORE_APPLICATION_UNLOAD will be sent to the listeners.
