public class ADFServletContextListener
extends Object
implements javax.servlet.ServletContextListener, javax.servlet.http.HttpSessionListener

The ADFServletContextListener initializes a WebApplication object and sets it as an attribute on the ServletContext.
When the ServletContext is destroyed, it destroys the associated WebApplication and attempts to clean up all server hosted objects in the current thread.
This class must be registered as a listener-class (in the web.xml file) for the web application.
