The example is tested with Chrome and Firefox on Ubuntu. It should work in all modern browsers as it relies on web-socket-js for websocket emulation in browsers that do not have native support. Please note the updated Usage instructions. The socket-policy-server necessary for Flash websocket emulation has to listen on port 843 (at least that is the first place Flash asks for the policy file) so the server has to be run using sudo.

If you are interested the example is at hosted on github, along with usage instructions.

I turned out to be quite a hassle to get it running so I thought I would document it here so others might save some time.

I have create a project on github that includes all the dependencies. I run it in Emacs using swank-clojure-project. The two last forms start the two servers – one is the websocket chat server, the other just serves the index.html file (this is necessary for the web_socket.js  to work). I have only been able to make this work in browsers with native websocket support (Chrome and Safari). If anybody can figure out what goes wrong in the other browsers (e.g. Firefox) let me know, and I will update.

I have uploaded the project to github at lein-war-test. Let me know what you think.
