Hi,
I'm struggling to make simple chat atmosphere application to work with
embedded undertow.
The app seems to connect to websocket, and requests are passing through to
AtmosphereHandler but response never reaches client. I suppose that I'm
missing something in my undertow configuration but don't know what. Same
code works when dropped into Tomcat or Jetty.
Here is my bootstrap class:
public class Bootstrap {
public static void main(String[] args) throws Exception {
// deploy to undertow
DeploymentInfo servletBuilder = Servlets.deployment()
.setClassLoader(Bootstrap.class.getClassLoader())
.setContextPath("")
.setDeploymentName("chat")
.setDefaultEncoding("UTF-8")
.setUrlEncoding("UTF-8")
.setResourceManager(new FileResourceManager(new File(""),
0))
.addWelcomePage("index.html");
servletBuilder.addServlet(Servlets.servlet("AtmosphereServlet",
AtmosphereServlet.class)
.addInitParam("org.atmosphere.cpr.AtmosphereHandler",
"org.atmosphere.samples.chat.Chat")
.addMapping("/chat/*")
.setAsyncSupported(true));
final WebSocketDeploymentInfo webSocketDeploymentInfo = new
WebSocketDeploymentInfo();
servletBuilder.addServletContextAttribute(WebSocketDeploymentInfo.ATTRIBUTE_NAME,
webSocketDeploymentInfo);
DeploymentManager manager =
Servlets.defaultContainer().addDeployment(servletBuilder);
manager.deploy();
HttpHandler servletHandler = manager.start();
PathHandler path =
Handlers.path(Handlers.redirect("/")).addPrefixPath("/",
servletHandler);
Undertow server = Undertow.builder()
.addHttpListener(8080, "0.0.0.0")
.setHandler(path)
.build();
server.start();
}
}
Does anyone know how to properly configure websockets support so that it
works with Atmosphere Framework?

Hi Dragan,
... I just had a similar issue a couple of days ago... my setup is
slightly different from yours (using Spring behind the scenes), but it
shouldn't matter...
The problem was (in my case) the Atmosphere servlet mapping and the path
parameter in the annotated handler service...
I had (like you) an asterisk ("*") in the servlet mapping and that lead
to a similar problem that you are describing (messages seem to arrive on
the server side, but broadcasts to subscribed clients don't work).
Also: Atmosphere was picky concerning the path parameter in my annotated
handler service (see below).
So... I'd suggest you try something like this (just showing the relevant
parts):
[java]
public class Bootstrap {
...
.addMapping("/chat")
...
// Not sure if this is required and related to your problem...
including it anyway...
final Xnio xnio = Xnio.getInstance("nio",
Undertow.class.getClassLoader());
final XnioWorker xnioWorker =
xnio.createWorker(OptionMap.builder().getMap());
final WebSocketDeploymentInfo webSockets = new
WebSocketDeploymentInfo().setWorker(xnioWorker);
servletBuilder.addServletContextAttribute(ATTRIBUTE_NAME, webSockets);
...
final DeploymentManager manager =
defaultContainer().addDeployment(servletBuilder);
manager.deploy();
// Not sure if it matters, but I don't use a path handler
Undertow server = Undertow.builder()
.addHttpListener("8080", "localhost")
.setHandler(manager.start())
.build();
server.start();
}
// Not sure if you are using the annotations... including it anyway... I
think at least the path parameter has to be defined (interceptors can
also be defined in servlet init param)... Atmosphere didn't pick the
handler in my case when left out
@Singleton
@ManagedService(
path = "/{id}",
broadcasterCache = UUIDBroadcasterCache.class,
interceptors = {AtmosphereResourceLifecycleInterceptor.class,
CorsInterceptor.class, TrackMessageSizeInterceptor.class,
SuspendTrackerInterceptor.class},
broadcaster = SimpleBroadcaster.class)
public class Chat {
...
}
[/java]
... and then on the client side:
[javascript]
var globalCallback = function (response) {
// do something
};
var roomId = '123';
var rq = $.atmosphere.subscribe('http://localhost:8080/chat/' + roomId,
globalCallback, $.atmosphere.request = {
enableXDR: true,
logLevel: 'debug',
contentType: 'application/json',
transport: 'websocket',
onError: function (response) {
},
onClose: function (response) {
},
onOpen: function (response) {
},
onMessage: function (response) {
},
onReopen: function (request, response) {
},
onReconnect: function (request, response) {
},
onMessagePublished: function (response) {
},
onTransportFailure: function (reason, request) {
},
onLocalMessage: function (request) {
},
onFailureToReconnect: function (request, response) {
},
onClientTimeout: function(request){
},
callback: function () {
}
});
[/javascript]
Note: I am using the latest 2.2.0-RC1 jars with Atmosphere JQuery 2.2.0
Hope it helps...
Cheers,
Aleks

Thanks for the quick reply, but unfortunately it didn't help.
I changed the mapping, removed asterisk, but it's still not working.
I'm not using any annotations or interceptors, it's the simplest setup
possible.
Just an ordinary AtmosphereHandler implementation. AtmosphereHander is
registered directly with AtmosphereFramework through init parameter of
AtmosphereServlet.
You can see the full code at:
https://github.com/djotanov/atmosphere-undertow
I thought that I missed some configuration parameter in undertow but it
seems that that is not the case since the same config works for you. I
guess I will have to dig deeper into undertow code.
Thanks,
Dragan
