Java socket.io client

Question

Is there any Socket.IO-client available for Java? So far I have only found the official Socket.IO client which is only available for JavaScript and socket.io-java which is only the server.

Limited options at this time:

sound right as far as WebSockets go. Socket.IO's specific wire protocol do not appear to have been implemented in Java yet, so you may have to deal with that yourself.

I finally went with Java-WebSocket by TooTallNate and implemented the Socket.IO-specific stuff myself. – Teo Klestrup Röijezon Apr 26 '11 at 00:19
Nice. Would love to hear how that worked out for you: are you using Java on both the client and the server, or java on the client and something like Node.js on the server? – Femi Apr 26 '11 at 06:37
I'm using Java on the desktop client, JavaScript (of course) on the web clients, and Python on the server. – Teo Klestrup Röijezon Apr 26 '11 at 09:10

@DontCare4Free Have you open-sourced your Socket.io Java client? – Kevin Jul 31 '11 at 08:52
@Kevin, https://github.com/dontcare4free/blservermanager-client/blob/master/src/main/java/tk/dontcare4free/blservermanager/Client.java, although I've had reports of it not working too well with the official node socket.io server. – Teo Klestrup Röijezon Jul 31 '11 at 19:33
I cant compile the socket.io-java-client project with ant. – Jānis Gruzis Jul 05 '12 at 13:12
Note that the Gottox client does not support the XHR-Transport protocol. – Erel Segal-Halevi Feb 12 '13 at 09:43

Judging from http://socket.io under "Supported Transports" it could be several different transport protocols:

WebSocket, Adobe® Flash® Socket, AJAX long polling, AJAX multipart streaming, Forever Iframe, JSONP Polling

So, the question is, what is your server supporting?

From the perspective of Java clients the easiest would be WebSockets.

Yes, the server supports WebSockets. I'm not sure though about if socket.io does any own magic or just connecting directly should do. – Teo Klestrup Röijezon Apr 25 '11 at 21:10

If you need a client side implementation, checkout java-socket.io.client I made it a few months ago and I believe some people have forked it and upgraded it to the latest version: https://github.com/clwillingham/java-socket.io.client

You can use socket.io-client.java.

See this link for src code.

You can also find a tutorial here

Take a look at http://techdroid.kbeanie.com/2011/03/websockets-on-android.html. I only needed the WebSockets, so I stripped out the WebView part as well, the Factory was superfluous also. You can just get away with using https://github.com/anismiles/websocket-android-phonegap/blob/master/src/com/strumsoft/websocket/phonegap/WebSocket.java and implement the SocketIO specifcs yourself.
