Class ApplicationListener

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

All Implemented Interfaces:

EventListener, javax.servlet.ServletContextListener

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

A ServletContextListener which bootstraps gCube management of a web application.

In servlet containers that implement version 3.0 or later of the specification, the listener may be bound to the application by a ApplicationInitializer packaged with the application or used as a shared library. If the container ignores ApplicationInitializers, the listener is bound by virtue of its WebListener annotation.

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

In all cases, the implementations handles redundant configurations to the effect that only only one listener can be bound to any given application.
