How to avoid redeclaring your web service interface?

Question

Hi there,
How can one avoid having to redeclare your wsdl interface on
each mxml page where it is accessed? I only want to declare the web
service and the operation is has once and then just include it in
the component where I use it to access/update data.
I am new to flex so this may be obviouse to other but not me.
I tried including it in its own mxml file and then using the normal
component include tag to include it. I get errors about not being
able to access the webservice via its id.
e.g.
Error: Access of undefined property WebService.
[mxmlc] WebService.getSiteOptions.send();
thanks

The solution is to place the web definition in a separate
file and then use the "include" like functionality of defining your
own namespace in the xml. You do the include in the main
application file.
eg
<mx:Panel
xmlns:mx="
http://www.adobe.com/2006/mxml"
xmlns:webservice="webservice.*"
width="100%"
height="100%"
title="Reports Menu"
creationComplete="onInit();" >
On the main application page to include your web service file
do a
<webservice:webservices id="services"/>
The webservices.mxml file will contain your definitions.
<?xml version="1.0" encoding="utf-8"?>
<mx:Canvas xmlns:mx="
http://www.adobe.com/2006/mxml"
height="0"
visible="false">
<mx:Script>
<![CDATA[
import mx.rpc.soap.mxml.WebService;
import mx.rpc.events.FaultEvent;
import mx.controls.Alert;
[Bindable]
public var webServiceWSDL:String ="
http://127.0.0.1:8080/jumpingbean/services/AddWebService?wsdl";
public function onServiceFault(evt:FaultEvent):void
var err:Error = new Error(evt.fault.faultCode + " , " +
evt.fault.faultString);
parentApplication.showError(err);
public function onSuccess(evt:Event):void
Alert.show(evt.toString());
]]>
</mx:Script>
<!-- ======================================== -->
<!-- Remote Services -->
<!-- ======================================== -->
<mx:WebService id="webservice"
wsdl="{this.webServiceWSDL}" service="ValueAddWebService"
port="AppWebServiceHttpPort" fault="onServiceFault(event)"
showBusyCursor="true" >
etc
In your child components you can refer to the component by
doing a "parentApplication.services.webservice"
