Grizzly 2.3.11 + Atmosphere 2.1.3: getServletPath() returns null

Question

I'm testing Atmosphere 2.1.3 using Grizzly 2.3.11. I've created a ManagedService(path="/chat"), but I get this error: 'No AtmosphereHandler maps request for /chat Status 500 Message Server Error'. If I change the path to ManagedService(path="/") it works. I've debugged a bit and it seems that org.atmosphere.cpr.AtmosphereRequest.getServletPath() returns null, so a default path "/" is used and that's the cause that makes my test work using ManagedService(path="/").

I'll appreciate your help because I need to use a path kinda ManagedService(path="/chat").

NOTE: this post is related to Atmosphere + Grizzly: No AtmosphereHandler maps request for /chat Status 500 Message Server Error

PD: This is my Main test class:

package com.dweb.atmosphere.grizzly;

public class Main {

    public static void main(String[] args) throws IOException {

        final HttpServer server = HttpServer.createSimpleServer(".", 8181);

        final WebappContext ctx = new WebappContext("ctx", "/");

        // enable web socket support
        final WebSocketAddOn addon = new WebSocketAddOn();

        for (NetworkListener listener : server.getListeners()) {
            listener.registerAddOn(addon);
        }

        // add atmosphere servlet support
        final AtmosphereServlet atmosphereServlet = new AtmosphereServlet();.

        final ServletRegistration atmosphereServletRegistration = ctx.addServlet("AtmosphereServlet", atmosphereServlet);

        atmosphereServletRegistration.setInitParameter(
                "org.atmosphere.websocket.messageContentType",
                "application/json");
        atmosphereServletRegistration.addMapping("/chat/*");
        atmosphereServletRegistration.setLoadOnStartup(1);

        // deploy
        ctx.deploy(server);

        try {
            server.start();
            System.out.println("Press enter to stop the server...");
            System.in.read();
        } finally {
            server.shutdownNow();
        }  
    }

[Grizzly(7) SelectorRunner] WARN org.atmosphere.websocket.protocol.SimpleHttpProtocol - org.atmosphere.cpr.AtmosphereMappingException: No AtmosphereHandler maps request for /chat Status 500 Message Server Error

Hi Alexey,

I'm debugging this issue, these are my tests & results:

-. When I call 'http://localhost:8181/chat/a/b/c' internally this request is built: 'AtmosphereRequest{ contextPath= servletPath=/chat pathInfo=/a/b/c requestURI=/chat/a/b/c destroyable=true}' Well, Http Get requests seem to work fine.

-. When I call 'new WebSocket('ws://localhost:8181/chat/a/b/c')' internally this request is built 'AtmosphereRequest{ contextPath= servletPath=null pathInfo=null requestURI=/chat/a/b/c destroyable=true}' I think the problem (servletPath & pathInfo are null) only happens when I use websockets

I'm debbuging the method org.glassfish.grizzly.websockets.WebSocketEngine.upgrade(FilterChainContext ctx, HttpContent requestContent, Mapper mapper) and the param requestContent receives this value:

HttpRequestPacket (
   method=GET
   url=/chat/a/b/c
   query=null
   protocol=HTTP/1.1
   content-length=-1
   headers=[
      upgrade=websocket
      connection=Upgrade
      host=localhost:8181
      origin=http://localhost:8080
      pragma=no-cache
      cache-control=no-cache
      sec-websocket-key=3pRm4vKnwqvRO8G0/WUNBw==
      sec-websocket-version=13
      sec-websocket-extensions=permessage-deflate; client_max_window_bits, x-webkit-deflate-frame
      user-agent=Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/34.0.1847.116 Safari/537.36]
)

but at the end of my debugging session the method org.atmosphere.util.DefaultEndpointMapper.computePath(AtmosphereRequest req) receives the param req with this value: AtmosphereRequest{ contextPath= servletPath=null pathInfo=null requestURI=/chat/a/b/c destroyable=true}

Well I hope these tests have some value for you, anyway if you need more tests feel free to ask.

Answer 1

The issue was found and fixed in Grizzly 2.3.12.

https://java.net/jira/browse/GRIZZLY-1680 The code should work as it is.
