Remote Object - not able to get the returned value from java method

Question

     Hi ,
I am developing one sample flex aplication that connects to the java code and displays the returned value from the
java method in flex client. Here I am able to invoke the java method but not able to collect the returned value.
lastResult is giving null .  I am able to see the sysout messages in server console.
I am using flex 3.2 and blazeds server  and java 1.5
Here is the code what I have written.
<?xml version="1.0" encoding="utf-8"?><mx:WindowedApplication  xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" backgroundColor="#FFFFFF" initialize="initApp()">
 <mx:Script><![CDATA[
import mx.controls.Alert; 
import mx.binding.utils.ChangeWatcher; 
import mx.rpc.events.ResultEvent; 
import mx.messaging.*; 
import mx.messaging.channels.* 
public function initApp():void { 
     var cs:ChannelSet = new ChannelSet(); 
     var customChannel:Channel = new AMFChannel("my-amf", "http://localhost:8400/blazeds/messagebroker/amf");     cs.addChannel(customChannel);
     remoteObj.channelSet = cs;
public function writeToConsole():void {      remoteObj.writeToConsole(
"hello from Flash client");
      var returnedVal:String = remoteObj.setName().lastResult;     Alert.show(returnedVal);
//[Bindable] 
// private var returnedVal:String; 
]]>
</mx:Script>
<mx:RemoteObject id="remoteObj" destination="sro" /> 
<mx:Form width="437" height="281">
 <mx:FormItem>  
</mx:FormItem>  
<mx:Button label="Write To Server Console" click="writeToConsole()"/>
 </mx:Form>
 </mx:WindowedApplication>
Java code
public  
     public SimpleRemoteObject(){  
          super();     }
  class SimpleRemoteObject { 
     public void writeToConsole(String msg) {          System.out.println("SimpleRemoteObject.write: " + msg);     }
     public String setName(){          System.
out.println("Name changed in Java"); 
          return "Name changed in Java";
And I have configured destination in  remote-config.xml
<destination id="sro">
   <properties>    
    <source>SimpleRemoteObject</source>
    <scope>application</scope>
   </properties>
  </destination>
Please help me .

You are not able to get the returned value because if you see the Remote object help you will realise you have to use result="resultfn()" and fault = "faultfn()"
In this you define what you wish to do.
More importantly in the remote object you need to define which method you wish to call using the method class like this
<mx:RemoteObject id="remoteObj" destination="sro" result="r1" fault="f1"  >
     <Method name="javaMethodName" result="r2" fault="f2"/>
<mx:RemoteObject>
r2 is the function where you get the result back from java and can use it to send the alert.
