Implementation of the WebSocket Specification

The goal of this project is to support the JSR 356 Java API for WebSocket using the Atmosphere Framework. The implementation will extends Atmosphere and will brings you Atmosphere's concepts like transport fallback (atmosphere.js), Broadcaster, Clustering, etc.

As simple as

@WebSocketEndpoint("/chat")
public class Jsr356WebSocketChat {

    private final ObjectMapper mapper = new ObjectMapper();

    @Broadcast("/chat")
    @WebSocketMessage
    public String onMessage(String message) throws IOException {
        return mapper.writeValueAsString(mapper.readValue(message, Data.class));
    }
}

Client side, as simple as:

    // We are now ready to cut the request
    var request = { 
        url: document.location.toString() + 'chat',
        contentType : "application/json",
        // Uncomment to allow sharing websocket amongst  windows/tabs
        //shared : true,
        transport : 'websocket'
    };

    subSocket = socket.subscribe(request);

    request.onOpen = function(response) {
      ...
    };

    request.onMessage = function (response) {
       ...
    };

    request.onError = function(response) {
        ...
    };
