Class LifetimeListener

java.lang.Object
  org.gcube.common.ghn.service.LifetimeListener

All Implemented Interfaces:

EventListener, javax.servlet.ServletContextListener

@WebListener
public class LifetimeListener
extends Object
implements javax.servlet.ServletContextListener

A ServletContextListener for managed services which notifies a ServiceManager of app lifetime events.

In servlet containers that implement version 3.0 or later of the specification, the listener is attached to the managed app by a ServiceInitializer packaged within the app or a shared library. If the container ignores ServiceInitializers, then the listener is attached to the managed app by virtue of its WebListener annotation.

In servlet containers that implement earlier versions of the specification, the listener must be configured in web.xml.

In all cases, the implementations handles redundant configurations, in that all the listener instances after the first one short-circuit their behaviour.
