Hello World
An introduction to any technology would not be complete without a “Hello World” example. This will give you some hands-on experience with the client-side and server-side code before diving into details. It also provides a sound basis for exploring Flash Remoting on your own.
First, we will look at the Flash code necessary to call the remote service, which is virtually the same regardless of which server-side technology implements the service. We will then look at the server-side code implemented in ColdFusion, Server-Side ActionScript, Java, ASP.NET, PHP, and as a SOAP-based web service.
Tip
The examples throughout the book assume that you have Flash Remoting installed and configured on your server, and that you have installed the Flash Remoting components for Flash MX. Chapter 2 covers Flash Remoting installation and configuration in more detail.
Flash ActionScript Code
The client-side ActionScript is virtually the same for each server-side service example. The only things that change are the path to the remote service when it is implemented as a web service and the path to the Flash Remoting gateway, which varies depending on the server implementation.
The client-side ActionScript code shown in Example 1-1 should be inserted on the first frame of the main timeline of a Flash movie, as shown in Figure 1-4.
