解决方案:

原因是因为使用JAX-WS调用webservcie时 ，没有指定Url地址，导致此错误的发生；

public class WebServiceClient {
 public static void main(String[] args) throws MalformedURLException {
  URL url = new URL("http://127.0.0.1:8080/WebService?wsdl");
     //第一个参数是webservice的URI；
     //第二个参数是发布的WebService服务的名字;
  QName qName = new QName("http://services.web.java.com/","StudentServiceImplService");
   //创建服务;
  //Service service = Service.create(qName);  //此处需要指定url;正确的如下：

   Service service = Service.create(url,qName);  
  //提取服务端口;
  StudentService studentService = service.getPort(StudentService.class);
  String result = studentService.sayHello("Zhangsan");
  System.out.println(result);
 }
}

缺少哪个包？

关于这个问题，百度的答案，太坑爹了。
费了我一天的时间，最后，在别人的帮助下，终于找到了答案
是少webservice调用需要的包。
