If you haven’t already done so, you need to set up a “class path” in Flash-this tells Flash where to find the source code for classes that you will be using in your projects (such as the code libraries used for XML-RPC). Download the other code listed in the requirements page (currently just the Flash Remoting components’ source code).
zip file containing the XML-RPC client library code The functionality of this example is identical to the “Simple Math Service” example above-except that the example is built with the code on a keyframe on the timeline rather than in a separate class. In this example, you’ll write code that will call a remote procedure that adds two numbers together. These steps walk you through the process of creating a Flash project (FLA) that makes an XML-RPC remote procedure call and displays the result on the screen. Shown in the Simple Math Service example, in the "sumAndDifference" method and its related methods.
