Jersey2-Chat sample with Embedded Jetty results in 404

[kirevse]

Since the system I am trying to integrate Atmosphere into uses embedded Jetty, I was trying to convert Jersey2-Chat sample to the same logic.

However, when I ran my server and entered a value into the input field, I got "org.atmosphere.websocket.WebSocket - 404 Not Found" on the server.

Here is the code for my server:

public class ChatServer {
    private Server server = null;

    public ChatServer() {
        ServletHolder atmosphereServletHolder = new ServletHolder(AtmosphereServlet.class);
        atmosphereServletHolder.setInitParameter("jersey.config.server.provider.packages", "org.atmosphere.samples.chat.jersey");
        atmosphereServletHolder.setInitParameter("org.atmosphere.websocket.messageContentType", "application/json");
        atmosphereServletHolder.setAsyncSupported(true);

        ServletContextHandler servletContextHandler = new ServletContextHandler(ServletContextHandler.SESSIONS);
        servletContextHandler.addServlet(atmosphereServletHolder, "/chat/*");   

        this.server = new Server(8084);
        this.server.setHandler(servletContextHandler);
    }

    public void start() throws Exception {
        this.server.start();
    }

    public void stop() throws Exception {
        this.server.stop();
    }

    public static void main(String[] args) throws Exception {
        ChatServer chatServer = new ChatServer();
        try {
            chatServer.start();
        } catch (Exception e) {
            e.printStackTrace();
            chatServer.stop();
        }
    }
}

My test was using Atmosphere 2.2.0-SNAPSHOT and jersey-container-servlet 2.8.
The only change made to the application.js was to hardcode the URL:

url: 'http://localhost:8084/chat'

so that the index.html can be ran from the file system.

The solution was to change the following line:

        servletContextHandler.addServlet(atmosphereServletHolder, "/chat/*");    

to:

        servletContextHandler.addServlet(atmosphereServletHolder, "/*");

At the same time a regular Jersey servlet works with the following line:

        servletContextHandler.addServlet(jerseyServletHolder, "/test/*");

Please, make this consistent.
Thank you!

From what I know, Jetty "cuts" from URI the part defined in web.xml, that is, in your case "/chat".
If the request is: /chat/whatever, and servlet is mapped to "/chat/*", Jetty will cut out "/chat" leaving only "/whatever" to match into Jersey resources.

Tomcat, for example, does not have this behaviour.

@bogdanbrindusan Yes fixing this issue won't be easy because of specific container behavior...but contribution welcomed if you have the cycle.
