Before you can use functions defined in your server-side ActionScript files, you must connect the Adobe Flash movie to the server-side Flash Remoting service. 
Create a Flash Remoting service connection
  - Include the necessary ActionScript classes in the first frame of the Flash movie that will be using server-side ActionScript functions. 
  - Use the following command to include the NetServices class: 
 
#include "NetServices.as"
  - (Optional) Use the following command to include the NetDebug class:
 
#include "NetDebug.as"
For more information about the NetDebug and RecordSet classes, see Using Flash Remoting.
   
  - Since the Flash Remoting service serves as a broker for calls to server-side ActionScript functions, you must identify the Flash Remoting service URL as an argument in the NetServices.setDefaultGatewayUrl function. For example:
NetServices.setDefaultGatewayURL("http://localhost:8500/flashservices")
You must specify a server hostname. The default port number for the Flash Remoting service is 8500. 
   
  - Create the gateway connection using the NetServices.createGatewayConnection function; for example:
gatewayConnection = NetServices.createGatewayConnection();
