public class CometEngine
extends CometEngine

Main class allowing Comet support on top of Grizzly Asynchronous Request Processing mechanism. This class is the entry point to any component interested to execute Comet request style. Components can be Servlets, JSP, JSF or pure Java class. A component interested to support Comet request must do: (1) First, register the cometContext path on which Comet support will be applied: CometEngine cometEngine = CometEngine.getEngine() CometContext cometContext = cometEngine.register(contextPath) (2) Second, add an instance of CometHandler to the CometContext returned by the register method: cometContext.addCometHandler(handler); (3) Finally, you can invokeCometHandler other CometHandler by doing: cometContext.invokeCometHandler(Object)(handler); You can also select the stage where the request polling happens when registering the cometContext path (see register(String,int);
