本文介绍了一个使用Flex编写的客户端通过WebService调用后台Java服务的示例。客户端通过按钮触发计算请求，将两个输入框中的整数传递给服务器端进行乘法运算，并展示返回结果。然而，在实际运行中发现虽然服务端正确响应，但结果未能显示在客户端界面上。

--------------------------------------------------------------------------

一下内容为一个flex写的一个客户端的代码。

<?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.FaultEvent;
     import mx.rpc.events.ResultEvent;
     import mx.controls.Alert;
     public function getSuccess(evt:ResultEvent):void
     {
           trace(evt.result as String);
           txtOUT.text=evt.result.toString();
     }

     public function getFault(evt:FaultEvent):void
     {
                 Alert.show(evt.message.toString(),"提示");
     }
   ]]>
   </mx:Script>

    <mx:WebService id="java_webservice" wsdl="http://localhost:8080/flexWS_server?wsdl"
                useProxy="false">
    <mx:operation name="getAnswer"
                result="getSuccess(event);"
                resultFormat="object"
                fault="getFault(event);">
          <mx:request>
             <arg0>{txtIN1.text}</arg0>
             <arg1>{txtIN2.text}</arg1>
          </mx:request>
    </mx:operation>
    </mx:WebService>

<mx:Canvas x="64" y="37" width="498" height="292" backgroundColor="#924A15">
  <mx:Button x="305" y="32" label="计算" width="71"
          height="36" fontSize="14" id="btn"
          click="java_webservice.getAnswer.send()"/>
  <mx:TextInput x="31" y="32" width="93" height="36"
             backgroundColor="#F9F9FA" color="#F97001"
             fontSize="15" id="txtIN1"/>

  <mx:TextArea x="31" y="76" width="457" height="206"
            fontSize="15" id="txtOUT"/>

  <mx:TextInput x="170" y="36" width="93" height="36"
             backgroundColor="#F9F9FA" color="#F1571A"
             fontSize="15" id="txtIN2"/>

  <mx:Label x="132" y="32" text="X" width="30" fontSize="28"
         color="#F5F9FA"/>
</mx:Canvas>

</mx:Application>

一下为要暴漏的接口，简单的加法Test.java

package fu.flexws;

import javax.jws.WebMethod;
import javax.jws.WebService;

@WebService
public interface Test {

@WebMethod
public String getAnswer(int i,int j);
}

--------------------------------------------------------------------------

上面接口的实现TestImpl.java

package fu.flexws;

import javax.jws.WebMethod;
import javax.jws.WebResult;

public class TestImpl implements Test {

@WebMethod
public String getAnswer(int i,int j) {

System.out.println("两个数相乘的结果是"+i*j);
return String.valueOf(i*j);
}

}

------------------------------------------------------------------

发布服务：

MainServer.java

package fu.flexws;

import org.apache.cxf.endpoint.Server;
import org.apache.cxf.jaxws.JaxWsServerFactoryBean;

public class MainServer {

public static void main(String[] args){

  JaxWsServerFactoryBean factory=new JaxWsServerFactoryBean();
  factory.setAddress("http://localhost:8080/flexWS_server");
  factory.setServiceClass(TestImpl.class);

  Server server=factory.create();
     System.out.println("服务器端启动了···············");
  server.start();

}
}
