public abstract class WebAppIntercepter
extends AbstractJBossService
implements javax.management.NotificationListener

Relay web deployments. When a web deployment occurs, it is abstracted into a PortalWebApp object that provides a consistent way to getPortalObjectContext informations and modify the web application.

When this service stops it does not send undeployment notifications, therefore it is up to the client of this service to perform any cleanup task associated to a deployment web application. The purpose of this is that most of the time clients of this service will be stopped before this one and they would receive undeployments in a not started state.
