All Implemented Interfaces:

ContainerListener, LifecycleListener

Direct Known Subclasses:

public abstract class FrameworkListener
extends Object
implements LifecycleListener, ContainerListener

This listener must be declared in server.xml as a Server listener, possibly optional. It will register a lifecycle listener on all contexts. This is an alternative to adding a Listener in context.xml with more flexibility.
