webservice xfire客户端出现问题，谁帮解决下

Question

用的是myeclipse8.0

自动生成的webservice服务器端

[color=red]1，自动生成的接口[/color]package com.test.service;
//Generated by MyEclipse

public interface IMyFirstWebS {

public String example(String message);

}

[color=red]2，实现类[/color]

package com.test.service;
//Generated by MyEclipse

public class MyFirstWebSImpl implements IMyFirstWebS {

public String example(String message) {
    return message+" My First Web Service!";

}

}
[color=red]
3，webservices/service.xml自动生成配置[/color]<?xml version="1.0" encoding="UTF-8"?>

<service>
    <name>MyFirstWebS</name>
    <serviceClass>com.test.service.IMyFirstWebS</serviceClass>
    <implementationClass>
        com.test.service.MyFirstWebSImpl
    </implementationClass>
    <style>wrapped</style>
    <use>literal</use>
    <scope>application</scope>
</service></beans>

4，发布到tomcat里访问 http://localhost:9000/WebServiceTest1/services/IMyFirstWebS?wsdl

Available Services:
MyFirstWebS [wsdl]
Generated by XFire ( http://xfire.codehaus.org )

5，建立客户端
我建立的是一个JAVA项目，但是导入了XFire 1.2 HTTP Client Libraries包
接口IMyFirstWebS.java我也复制到这个项目里了，又写了个测试类main1
import java.net.MalformedURLException;
import java.net.URL;

import org.codehaus.xfire.XFireFactory;
import org.codehaus.xfire.client.Client;
import org.codehaus.xfire.client.XFireProxyFactory;
import org.codehaus.xfire.service.Service;
import org.codehaus.xfire.service.binding.ObjectServiceFactory;

public class main1 {
public static void main(String[] args) throws MalformedURLException, Exception {
Service srvcModel = new ObjectServiceFactory().create(IMyFirstWebS.class);
XFireProxyFactory factory =new XFireProxyFactory(XFireFactory.newInstance().getXFire());
String helloWorldURL = "http://localhost:9000/WebServiceTest1/services/MyFirstWebS?wsdl";
try {
IMyFirstWebS srvc = (IMyFirstWebS)factory.create(srvcModel, helloWorldURL);
String result = srvc.example("hello world");
System.out.print(result);
} catch (MalformedURLException e) {
e.printStackTrace();
}
}
}
直接运行报错

Exception in thread "main" org.codehaus.xfire.XFireRuntimeException: Could not invoke service.. Nested exception is org.codehaus.xfire.fault.XFireFault: There must be a method name element.

我试过了好多种测试方法
还有这种

public class main1 {
public static void main(String[] args) throws MalformedURLException, Exception {
Client client;
client =new Client(new URL("http://localhost:9000/WebServiceTest1/services/IMyFirstWebS?WSDL"));
Object[] results=client.invoke("example", new Object[]{"hello"});
System.out.println((String)results[0]);
}
}

最后都是不对，到底哪配错了呢，服务端我访问正常，但是在java类里就是不好使，都愁死了，客户端我也建立web service client了但是也是不行

Answer 1

[code="java"] String helloWorldURL = "http://localhost:9000/WebServiceTest1/services/MyFirstWebS?wsdl"; [/code]

改成
[code="java"]
String helloWorldURL = "http://localhost:9000/WebServiceTest1/services/MyFirstWebS";
[/code]

试试~~~
