Hello World

Server-Side Code

In the next section, you’ll create the remote service required by this simple Flash

movie. Once you have created the remote service, you can test the Flash movie using

Control

➝ Test Movie. You should get the following output displayed in the Output

window:

Data received from Server : Hello World from servertype

If you do not get this result:

• Set the Output window to verbose mode (Window

➝ Output ➝ Options ➝

Debug Level ➝ Verbose).

• Make sure that the server where the Flash Remoting gateway is installed is run-

ning and accessible.

• Make sure that there are no syntax errors in your client-side ActionScript code or

server-side code.

ColdFusion MX

For the ColdFusion MX example, we will implement the remote service as a Cold-

Fusion Component (CFC). CFCs are new to ColdFusion MX and provide an object-

based approach to ColdFusion development. They are ideally suited to Flash

Remoting. CFCs are discussed in depth in Chapter 5.

Create a file named HelloWorld.cfc and place it into the following directory, where

webroot is the root of your web server and com\oreilly\frdg\ matches the service path

specified by the initial portion of the

myServicePath variable in Example 1-1:

webroot\com\oreilly\frdg

Example 1-2 shows the code that must be added to your HelloWorld.cfc component:

This is a simple component that contains one function, sayHello( ), which returns a

string. Notice that we set the

access to "remote", which is necessary to allow the

component to be called remotely, either by Flash or as a web service.

Save the component. If you have access to the ColdFusion administrative interface

(which you should if you have a local installation) browse to it through your browser

with the following URL:

http://

yourservername/com/oreilly/frdg/HelloWorld.cfc/
