我是Web服务新手。我正在尝试通过Axis2引擎实现一个示例WSDL Web服务。

Versions: Axis2 - > axis2-1.1.1, Ant - > apache-ant-1.8.2

创建Web服务时没有任何错误。当我通过命令提示符（Ant测试）进行测试时，我收到如下错误

[java] Exception in thread "main" org.apache.axis2.AxisFault: Please implem
ent jdl.helloworld.webservices.service.HelloWorldSkeleton#SayHello
     [java]     at org.apache.axis2.description.OutInAxisOperationClient.send(Ou

     [java]     at jdl.helloworld.webservices.client.Client.main(Unknown Source)

     [java] Java Result: 1

这是HelloWorldServiceSkeleton.javajdl\helloworld\webservices\服务目录下的www.example.com

package jdl.helloworld.webservices.service;

import org.apache.ws.axis2.helloworld.SayHello;
import org.apache.ws.axis2.helloworld.SayHelloResponse;
import org.apache.ws.axis2.helloworld.PrintValues;

public class HelloWorldServiceSkeleton 
{
    public org.apache.ws.axis2.helloworld.SayHelloResponse SayHello(org.apache.ws.axis2.helloworld.SayHello param0)throws Exception {
        SayHelloResponse sayHelloResponse=new SayHelloResponse();
        try{

            sayHelloResponse.setName(param0.getName());
            System.out.println("Hello World Service called");
        }catch(Exception e){
            System.out.println(" Error Occured : "+e);
        }
        return sayHelloResponse;
    }

    public String PrintValues(org.apache.ws.axis2.helloworld.PrintValues param1){
        return "printvalues";
    }

}

        System.out.println(" --> sayHello Begin");
        SayHello sayHello=new SayHello();
        sayHello.setName("user");       
        SayHelloResponse sayHelloResponse=helloWorldStub.SayHello(sayHello);            
        System.out.println(" --> sayHello Response : "+sayHelloResponse.getName());
