import mx.rpc.RelayResponder;
import mx.rpc.FaultEvent;
import mx.remoting.PendingCall;
// get a reference to the ASPX-based service
var ASPXservice:Service = new Service("http://localhost/myASPApp/
default.aspx",null,"myASPApp",null,null);
// call the ASPX page
var pc:PendingCall = ASPXservice.myASPPage();
pc.responder = new RelayResponder(this, "myASPPage_Result",
"myASPPage_Fault");
// handler for ASPX page results
function myASPPage_Result(re:ResultEvent):Void
{
DataGlue.bindFormatStrings(displayNames, re.result, "#SSN#","#ID#");
}
You can also use the DataGlue.BindFormatFunction function to create custom formatting for
your record sets. For more information on displaying record sets in ActionScript, see Chapter 4,
“Using Flash Remoting Data in ActionScript,” on page 63.
Calling web services from Flash
Using the Flash Remoting web service adapter, you can call web services from Flash that are
described by the Web Services Description Language (WSDL). You must first generate a local
web service proxy to interact with web services. After you create the proxy, the ActionScript in
your Flash application can then invoke web service methods through the proxy, which handles
sending and receiving Simple Object Access Protocol (SOAP) messages with the remote web
service.
In .NET, you can generate proxy assemblies with the WSDL Tool (wsdl.exe). Flash Remoting for
.NET also uses the WSDL Tool to generate SOAP proxies for web services automatically from
valid WSDL, either local or remote. In addition, Flash Remoting does not restrict you to
.NET-based web services. Rather, any WSDL-described web service is available to Flash
Remoting.
If you want to invoke web services using a .NET web service proxy assembly of your own that
contains the web service definition, place the DLL file into the local assembly cache of your
ASP.NET application. The proxy DLL must have exactly the same name as the web service, as
described by the WSDL’s service element. To invoke the web service proxy from ActionScript,
supply the web service’s fully qualified WSDL URL as the service address argument of the
Service constructor, and use the web service’s method names as the service function names.
