108 Chapter 6: Using Flash Remoting with ColdFusion MX

The following example replicates the helloWorld() function that was previously implemented as

a ColdFusion page. For more information, see “Using Flash Remoting with ColdFusion pages”

on page 97.

To create a ColdFusion component that interacts with a Flash application:

Create a ColdFusion component, and save it as flashComponent.cfc in the helloExamples

directory.

Edit flashComponent.cfc so that it appears as follows:

</cffunction>

</cfcomponent>

This example creates the helloWorld function. The cfreturn tag returns the result to the

Flash application.

Save the file.

The following ActionScript example calls this function:

import mx.remoting.Service;

import mx.remoting.PendingCall;

//…

var CFCService:Service = new Service(

"http://localhost/flashservices/gateway",

null,

"helloExamples.flashComponent",

null,

null);

var pc:PendingCall = CFCService.helloWorld();

For ColdFusion components, the component filename, including the directory structure from the

web root, serves as the service name. Remember to use a period to delimit the path directories,

rather than a backslash.

Accessing ActionScript objects

ActionScript supports the object initializer syntax when calling a function. For example, the

following function call passes two parameters as objects:

myService.myMethod({x:1, y:2});

In this example, the function passes x with a value of 1 and y with a value of 2.

In your component, you can access objects using the object name, as in the following example:
