If you have BlazeDS and looked at the examples, then you know how to connect to
the backend.
To do in Caingorm, just read the docs: http://www.cairngormdocs.org/
<http://www.cairngormdocs.org/>
Basically your command class will use a delegate class to call the server. The
delegate class will use the ServiceLocator to get a reference to the
appropriate service defined in the Services.mxml file.
<!-- Services.mxml -->
<cairngorm:ServiceLocator xmlns:mx="http://www.adobe.com/2006/mxml";
xmlns:cairngorm="com.adobe.cairngorm.business.*" >
<!-- SystemServices remote reference -->
<mx:RemoteObject id="systemServices" destination="systemService"
concurrency="single"
showBusyCursor="false" />
</cairngorm:ServiceLocator>
<!-- Delegate -->
package com.optimal.bluebird.business {
import com.adobe.cairngorm.business.ServiceLocator;
/**
* @author Dimitrios Gianninas
*/
public class SystemDelegate {
private var service:Object;
private var responder:IResponder;
/**
* Default Constructor
*/
public function SystemDelegate( responder:IResponder ) {
service = ServiceLocator.getInstance().getRemoteObject( "systemServices" );
this.responder = responder;
}
/**
* Loads static lists used by the UI.
*/
public function getStaticLists():void {
var call:AsyncToken = service.getStaticLists();
call.addResponder( responder );
}
}
}
// Command class
package com.optimal.bluebird.commands.system {
public class GetStaticListsCmd implements ICommand, IResponder {
/**
* Default Constructor
*/
public function GetStaticListsCmd() {
}
override public function execute( evt:CairngormEvent ):void {
var delegate:SystemDelegate = new SystemDelegate( this );
delegate.getStaticLists();
}
public function result( event:Object ):void {
// handle results
}
public function fault( event:Object ):void {
// handle fault
}
}
}

Subject: [flexcoders] Cairngorm - BlazeDS Example
Does any know of a good example of a Cairngorm project that uses a
BlazeDS backend service? I am having problem delegate to connect to
the backend server. Any help would be greatly appreciated.
