This appendix explains how to use the NetServices object to create a gateway connection and
return a Connection object. It also explains how to handle results and error information that are
returned by a service. This appendix covers the following topics:

Creating a gateway connection using the NetServices object
Note:
Although using NetServices to create a Connection object is still supported, in Macromedia
Flash MX 2004, Macromedia recommends that you create a gateway connection using the Service
object. For more information, see the Service class in Flash Remoting ActionScript Dictionary Help.
To create a Flash Remoting Connection object, you first specify the gateway URL and then create
a Connection object that uses it. You have several options for accomplishing these operations,
including the following:
•
You can use the
NetServices.createGatewayConnection()
method to specify the URL and
create the Connection object.
•
You can use a
NetServices.setDefaultGatewayUrl()
method to specify a default gateway,
and use the
NetServices.createGatewayConnection()
method without a URL to create
the Connection object. Flash Remoting uses the default gateway for all connections that you
create without otherwise specifying a gateway.
•
You can specify the gateway in the web page you use to deploy the Flash SWF file, and use the
NetServices.createGatewayConnection()
method without a URL to create the
Connection object.
