Features

• Supports 0.8+ version of Socket.IO-client up to latest - 0.9.5
• Supports xhr-polling transport

#Usage example

##Server

SocketIOListener handler = new SocketIOListener() {

	@Override
	public void onMessage(SocketIOClient client, String message) {
        ...
	}

	@Override
	public void onDisconnect(SocketIOClient client) {
        ...
	}

	@Override
	public void onConnect(final SocketIOClient client) {
        ...
	}

	@Override
	public void onJsonObject(SocketIOClient client, Object obj) {
        ...
                    SampleObject obj = new SampleObject();
                    // send object to socket.io client
                    client.sendJsonObject(obj);
	}
};

SocketIOServer server = new SocketIOServer();
server.setHostname("localhost");
server.setPort(81);
server.setHeartbeatThreadPoolSize(8);
server.setWorkerThreadPoolSize(8);
server.setBossThreadPoolSize(4);
server.setListener(handler);
server.start();

...

server.stop();

##Client

    <script type="text/javascript" src="socket.io.js" charset="utf-8"></script>

    <script type="text/javascript">
           var socket = io.connect('http://localhost:81', {
             'transports' : [ 'xhr-polling' ],
             'reconnection delay' : 2000,
             'force new connection' : true
           });
           socket.on('message', function(data) {
                // here is your handler on messages from server
           });

           // send json-object to server
           var obj = ...
           socket.json.send(obj);
