Both the PHP JSON-RPC server and an JSON-RPC example application are available in qooxdoo-contrib. The PHP JSON-RPC server is really quite simple. You’ll find it in In the qooxdoo-contrib RpcPhp directory. In RpcPhp/trunk, you’ll find a file called README.CONFIGURE which tells you how to install the server.

You’ll then want to use the qooxdoo-contrib application in RpcExample which tests all of the RPC primitives and provides a complete example of how to use the JSON-RPC services.

For writing your own services, just look at the documentation in RpcPhp/trunk/services/index.php (the actual server implementation) and at the services used by the example application, which you’ll find in RpcPhp/trunk/services/qooxdoo/test.php
