How to initialize a JSON-RPC Service:

	//You need the package of course
	dojo.require("dojo.rpc.JsonService");

	// Create a callback function to handle the results generated by a method
	// A second optional parameter to your call back will allow the callback to use
	// the submission Id of the json-rpc request

        function contentCallBack(result) {
	 	dojo.debug("in contentCallBack");
                var handlerNode = document.getElementById("content");
                handlerNode.innerHTML = result;
        }

	// Create a new object
        var testClass = new dojo.rpc.JsonService("testClass.smd");
