Registering the Servlet with the Comet Engine

1. In the servlet's init method, add the following code to get the component's context path:

   ServletContext context = config.getServletContext();
   contextPath = context.getContextPath() + "/hidden_comet";

2. Get an instance of the Comet engine by adding this line after the lines from step 1:

    CometEngine engine = CometEngine.getEngine();

3. Register the component with the Comet engine by adding the following lines after those from step 2:

   CometContext cometContext = engine.register(contextPath);
   cometContext.setExpirationDelay(30 * 1000);
