如何用xfire做一个webService用jaxb2绑定
我是一个SOA新学者,用xfire的jaxb2绑定做了一个例子，总是报错，也不清楚为什么了!
希望大家多给我一点意见，谢谢！

例子如下：
PO类：

package com.xxx.services;import java.io.Serializable;public class User implements Serializable {private String name;private int age;public int getAge() {return age;}......//getter() or setter();}

Service Interface类：

package com.xxx.services;import java.util.List;import javax.jws.WebMethod;import javax.jws.WebService;@WebService(name="UserServiceIntf", targetNamespace="http://www.webservicex.net")public interface UserService {@WebMethodpublic User getUser();@WebMethodpublic List getUsers();}

Service Interface Implement类：

package com.xxx.services;import java.util.List;import java.util.Vector;import javax.jws.WebService;import javax.jws.soap.SOAPBinding;@WebService(endpointInterface="org.codehaus.xfire.jaxb.UserService", serviceName="UserService")@SOAPBinding(parameterStyle=SOAPBinding.ParameterStyle.BARE)public class UserServiceImpl implements UserService {public User getUser(){User user = new User("tom",23);return user;}public List getUsers(){List list=new Vector();User user1 = new User("tom",23);User user2 = new User("jerry",26);list.add(user1);list.add(user2);return list;}}

src\META-INF\xfire\services.xml:

<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://xfire.codehaus.org/config/1.0">    <service>    <name>UserService</name>    <namespace>http://com.xxx.services/UserService</namespace>    <serviceBean>com.xxx.services.UserServiceImpl</serviceBean><serviceFactory>#jaxbServiceFactory</serviceFactory>    </service>        <bean name="jaxbServiceFactory" name="code"><?xml version="1.0" encoding="UTF-8"?><web-app version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"><servlet>         <servlet-name>XFireServlet</servlet-name>         <servlet-class>                 org.codehaus.xfire.transport.http.XFireConfigurableServlet         </servlet-class>     </servlet>          <servlet-mapping>         <servlet-name>XFireServlet</servlet-name>         <url-pattern>/servlet/XFireServlet/*</url-pattern>     </servlet-mapping>      <servlet-mapping>         <servlet-name>XFireServlet</servlet-name>          <url-pattern>/services/*</url-pattern>     </servlet-mapping></web-app>

报如下错误：

在xfire的官网上看好象还需要一个.xsd，然后再配到services.xml中，我也试了！错误一样！
希望大家可以帮我一下，看看什么问题，给点意见！最好说的具体点，谢谢！
