'Flex-able' Programming: Document-Literal Web Services and Flex

Document-Literal Web Services and Flex

Flex 2 supports both RPC and doc-literal web services. If you're interested in the difference, I found an article on the IBM developer works site to be very helpful (http://www-128.ibm.com/developerworks/library/ws-whichwsdl/). Using xmethods.net I found a simple document-literal web service that, given a URL it will return all of the hyperlinks contained in the HTML document. I then went ahead a built a simple Flex client that consumes the web service. Note, the web service doesn't allow Flash client access (it has no crossdomain.xml), so I went ahead and use the Flex Enterprise Service proxy service to proxy the communication. Below you'll find the code and the snippet from my flex-proxy-service.xml that enables the proxying.

Flex-proxy-services.xml

<destination id="myDocLitWS">
<properties>
// the location of the wsdl defined for soap proxy services
<wsdl>http://www.atomic-x.com/xmlservices/HyperlinkExtractor.asmx?wsdl</wsdl>

// the soap endpoints available for access defined for soap proxy services
<soap>http://www.atomic-x.com/xmlservices/HyperlinkExtractor.asmx</soap>
</properties>

// a specific adapter ref for the destination may be defined
<adapter ref="soap-proxy"/>
</destination>

doc-lit_example.mxml

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.macromedia.com/2005/mxml" verticalGap="10">

<mx:WebService id="myDocLitService" destination="myDocLitWS" result="myGrid.dataProvider=event.result">
<mx:operation name="ExtractUrl">
<mx:request>
<aUrl>{theURL.text}</aUrl>
</mx:request>
</mx:operation>
</mx:WebService>

<mx:HBox>
<mx:Label text="Enter a URL and click the button to see all the hyperlinks:"/>
<mx:TextInput id="theURL"/>
</mx:HBox>

<mx:Button label="Invoke Web Service" click="myDocLitService.ExtractUrl.send()"/>

<mx:DataGrid id="myGrid" width="100%"/>

</mx:Application>
