> 1. If listener stop method throws any exception then the webserver stop
> method will not be called
> {code}
> public void stop() throws Exception {
> listener.close();
> webServer.stop();
> }
> {code}
> 2. also, WebAppContext stores all the context attributes, which does not get
> cleared if only webServer is stopped.
> so following calls are necessary to ensure clean and complete stop.
> {code}
> webAppContext.clearAttributes();
> webAppContext.stop();
> {code}
> 3. Also the WebAppContext display name can be the name passed to HttpServer
> instance.
> {code}
> webAppContext.setDisplayName(name);
> {code}
> instead of
> {code}
> webAppContext.setDisplayName("WepAppsContext");
> {code}
