Re: [jetty-users] WebAppContext setAttribute()

[Joakim Erdfelt <joakim@xxxxxxxxxxx>]

WebAppContext.setAttribute() is at the entire WebApp level.

Yet ServletContext is at a specific Servlet level.

Using embedded mode, one way to accomplish what you want is to to specify the ServletContexts manually, 

http://git.eclipse.org/c/jetty/org.eclipse.jetty.project.git/tree/example-jetty-embedded/src/main/java/org/eclipse/jetty/embedded/ManyServletContexts.java?h=jetty-8

And the ServletContextHandler.setAttribute() calls would have the effect you are looking for.

I have setup the following Jetty embedded server and my own object in the following way.

            MessagebusContainer messagebus  = new MessagebusContainer();
            server = new Server(serverPort);

            WebAppContext webapp = new WebAppContext();
            webapp.setContextPath("/");
            webapp.setWar(user_dir + "/webapps/my.war");
            webapp.setAttribute("messagebus", messagebus);

            HandlerCollection handlers = new HandlerCollection();
            handlers.setHandlers(new Handler[]{webapp, new DefaultHandler()});

            server.setHandler(handlers);

            server.start();
            server.join();

Then in my war I have the following code in my servlet.

        MessagebusContainer messagebus = (MessagebusContainer) request.getServletContext().getAttribute("messagebus");

and I have tried.

        MessagebusContainer messagebus = (MessagebusContainer) request.getAttribute("messagebus");

but messagebus object is always NULL. Is there a way to pass objects to servlets through the context?
