Is ReST over websockets possible?

Question

I am planning to develop a web based chat application which takes in ReSTful requests, translate them to XMPP and deliver them to an XMPP server.

I don't understand why you would convert XMPP into REST and then run REST over WS. The point of WebSocket is to take the XMPP protocol directly to the browser, thereby avoiding all of the translation issues.

There are JavaScript libraries that can talk XMPP from the browser to the server. All you need is to proxy the XMPP traffic from WS over into TCP and then straight into your XMPP server. Kaazing has a gateway that allows you to do this.

If you want to use open source, you will need to write a JavaScript XMPP library. There are examples that show how to write a JS library for simple protocols. You just have to find one and extend the concept to the XMPP protocol.

So to recap, here are the way the architecture would look:

Your XMPP Client code <-> XMPP JavaScript Library <-> WebSocket over http <-> WebSocket to TCP Proxy <-> XMPP Server

where the XMPP Client code and the XMPP JavaScript Library runs in the browser, and the WS to TCP proxy along with the XMPP server are all server-side.
