Class ServiceWatcher

java.lang.Object

org.eclipse.jetty.osgi.boot.internal.webapp.ServiceWatcher

All Implemented Interfaces:

org.osgi.util.tracker.ServiceTrackerCustomizer

public class ServiceWatcher
extends Object
implements org.osgi.util.tracker.ServiceTrackerCustomizer

ServiceWatcher When a ContextHandler is activated as an osgi service we find a jetty deployer for it. The ContextHandler could be either a WebAppContext or any other derivative of ContextHandler. ContextHandlers and WebApps can also be deployed into jetty without creating them as osgi services. Instead, they can be deployed via manifest headers inside bundles. See BundleWatcher.
