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

    Shivakumar Nekar

           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"?>



      xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" backgroundColor="#FFFFFF" initialize="initApp()">






      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");


           remoteObj.channelSet = cs;






      public function writeToConsole():void {


      "hello from Flash client");



           var returnedVal:String = remoteObj.setName().lastResult;







      // private var returnedVal:String;








      <mx:RemoteObject id="remoteObj" destination="sro" />



      <mx:Form width="437" height="281">






      <mx:Button label="Write To Server Console" click="writeToConsole()"/>









      Java code

















           public SimpleRemoteObject(){










      class SimpleRemoteObject {




           public void writeToConsole(String msg) {


      out.println("SimpleRemoteObject.write: " + msg);






           public String setName(){


      out.println("Name changed in Java");



                return "Name changed in Java";







      And I have configured destination in  remote-config.xml


      <destination id="sro">





      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"/>



          r2 is the function where you get the result back from java and can use it to send the alert.
