Re: [jetty-users] Jetty to WAR Class Comunication

[Guy Hillyer <jetty-users@xxxxxxxxxxxxxx>]

You can make any arbitrary object in the parent app available to the
servlet via WebAppContext.setAttribute/getAttribute:

        MyService myService = new MyService();
        jetty = new Server(httpPort);
        wac = new WebAppContext();
        wac.setContextPath(...);
        wac.setWar(...);
        wac.setAttribute("myService", myService);
        jetty.setHandler(wac);
        jetty.start();

Then, in a servlet:

        MyService myService = (MyService)
            getServletContext().getAttribute("myService");

Hope that helps.
