试用main方法发布webservice遇到的问题

Question

我初学webservice，按照书上的例子自己敲了一个Demo。
如下：

package server.soap.bobo.net.bean;

import javax.xml.bind.annotation.XmlRootElement;

@XmlRootElement(name = "Student")
public class Student
{
    private String name;
    private int age;
    private String sex;
    public String getName()
    {
        return name;
    }
    public void setName(String name)
    {
        this.name = name;
    }
    public int getAge()
    {
        return age;
    }
    public void setAge(int age)
    {
        this.age = age;
    }
    public String getSex()
    {
        return sex;
    }
    public void setSex(String sex)
    {
        this.sex = sex;
    }
}

package server.soap.bobo.net.service;

import javax.jws.WebService;

import server.soap.bobo.net.bean.Student;

@WebService
public interface IStudentService
{
    public Student selectMaxAgeStudent(Student stu1 , Student stu2);
}

实现类：

package server.soap.bobo.net.service.impl;

import server.soap.bobo.net.bean.Student;
import server.soap.bobo.net.service.IStudentService;

public class StudentServiceImpl implements IStudentService
{
    @Override
    public Student selectMaxAgeStudent(Student stu1, Student stu2)
    {
        if (stu1.getAge() >= stu2.getAge())
        {
            return stu1;
        }
        else
        {
            return stu2;
        }
    }
    
}

 发布服务：

package server.soap.bobo.net.server;


import javax.xml.ws.Endpoint;

import server.soap.bobo.net.service.impl.StudentServiceImpl;


public class SoapServer
{
    public static void main(String[] args)
    {
        Endpoint.publish("http://127.0.0.1:8040/StudentService" , new StudentServiceImpl());
    }
}

 以上代码是在MyEclipse中编辑的，使用main方法发布，却报NullPointerException:

Exception in thread "main" java.lang.NullPointerException
    at com.sun.xml.internal.ws.server.EndpointFactory.getWsdlLocation(EndpointFactory.java:385)
    at com.sun.xml.internal.ws.transport.http.server.EndpointImpl.getPrimaryWsdl(EndpointImpl.java:265)
    at com.sun.xml.internal.ws.transport.http.server.EndpointImpl.createEndpoint(EndpointImpl.java:208)
    at com.sun.xml.internal.ws.transport.http.server.EndpointImpl.publish(EndpointImpl.java:138)
    at com.sun.xml.internal.ws.spi.ProviderImpl.createAndPublishEndpoint(ProviderImpl.java:90)
    at javax.xml.ws.Endpoint.publish(Endpoint.java:170)
    at server.soap.bobo.net.server.SoapServer.main(SoapServer.java:13)

 请各位指点一下！

你发布服务得要服务器是吧,myeclipse中的ws的框架是xfire,好像只有cxf才能在main里面自定义服务路径吧.去下个CXF,把里面的全部jar粘到你项目的lib中.cxf内置了一个服务器jetty.可以直接通过运行main方法发布服务
