首先看一个简单的java类:

Java代码

package com.test;  
 
public class TestVo {  
    public String toSayHello(String str) {  
        return " to say hello " + str;  
    }  
} 

package com.test;

public class TestVo {
 public String toSayHello(String str) {
  return " to say hello " + str;
 }
}

接着我们需要在 remoting-config.xml中配置 增加如下代码:

Java代码

<destination id = "myJavaClassRemoteObject">  
        <properties>  
            <source>com.test.TestVo</source>  
            <scope>application</scope>  
        </properties>  
    </destination> 

<destination id = "myJavaClassRemoteObject">
  <properties>
   <source>com.test.TestVo</source>
   <scope>application</scope>
  </properties>
 </destination>

下面的这个mxml中调用了这个TestVo

Java代码

<?xml version="1.0" encoding="utf-8"?>  
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute">  
    <mx:Script>  
        <![CDATA[  
            import  mx.rpc.events.ResultEvent;  
            import mx.controls.Alert;  
              
            private function callVO(str:String):void{  
                javaVo.toSayHello(str);  
                javaVo.addEventListener(ResultEvent.RESULT,getVo);  
            }  
              
            private function getVo(e:ResultEvent):void{  
                Alert.show(e.result.toString());  
            }  
        ]]>  
    </mx:Script>  
 
    <mx:RemoteObject  id="javaVo" destination="myJavaClassRemoteObject" />  
    <mx:Button click="callVO(’你好’)" label="请求"    height="50" width="100" />  
 
</mx:Application> 

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute">
 <mx:Script>
  <![CDATA[
   import  mx.rpc.events.ResultEvent;
   import mx.controls.Alert;
   
   private function callVO(str:String):void{
    javaVo.toSayHello(str);
    javaVo.addEventListener(ResultEvent.RESULT,getVo);
   }
   
   private function getVo(e:ResultEvent):void{
    Alert.show(e.result.toString());
   }
  ]]>
 </mx:Script>

 <mx:RemoteObject  id="javaVo" destination="myJavaClassRemoteObject" />
 <mx:Button click="callVO(’你好’)" label="请求"    height="50" width="100" />

</mx:Application>

这个项目是在myeclipse6.0中建立的，首先需要建立成flex project ,然后需要将其变成web project ,就OK了。
