Pulling Data from an imported web service into a data grid - Flex 3.0

Question

Hi all,
I have created a web service from Oracle using JDeveloper and imported it into my Fex 3 project, and I am trying to populate a data grid with the data from the web service.  I was trying to emulate the example found in my Adobe Flex 3.0 for Dummies book (see http://dougmccune.com/flexfordummies/chapter14/srcview/index.html), and while the code from the book with that data service works fine, I can't get my application to work.  My issue is with the part of code mx:DataGrid dataProvider="(service)"  - I do not know how to specify what to use for the data source to populate the data grid from my imported web service.  Any suggestions or examples would be helpful, as I am a newcomer to Adobe Flex.  My code is as follows:
<?xml version="1.0" encoding="utf-8"?><mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"xmlns:webservices="
generated.webservices.*">
 <mx:Script>
<![CDATA[
 private function getData():void {service.getPdRec(ageDt.text);
]]>
</mx:Script>
 <webservices:PD_Pct_Web_Service id="service" />
 <mx:VBox>
 <mx:HBox width="100%">
 <mx:TextInput id="ageDt" width="100%" />
 <mx:Button id="submitButton" label="Search" click="getData()" />
 </mx:HBox>
 <mx:DataGrid dataProvider="(service.getPdRec_lastResult
" rowHeight="
58" width="100%" height="300">
 <mx:columns>
 <mx:DataGridColumn dataField="creditManager" headerText="Credit Manager" width="40" />
 <mx:DataGridColumn dataField="pdTarget" headerText="PD Target" width="40" />
 <mx:DataGridColumn dataField="totalPd" headerText="Total PD" width="40" />
 <mx:DataGridColumn dataField="pdPct" headerText="PD Percent" width="50" />
 </mx:columns>
 </mx:DataGrid>
 </mx:VBox>
 </mx:Application>
My web service returns the following when invoked:

Answer 1

Use data binding. <mx:DataGrid dataProvider="{service.getPdRec_lastResult}"
