新建一个服务端项目：
　　1、定义一个接口如下：
/**
* 定义webservices接口
* @author Administrator
*
*/
@WebService
public interface IHelloService {
public String sayHello(String name);
public User  getUser(User user);
}
　　2.实现接口
/**
* 实现webservices接口
* @author Administrator
*
*/endpointInterface 实现的接口类
@WebService(endpointInterface="com.chni.webservies.IHelloService")
public class HelloServiceImpl implements IHelloService {
public User getUser(User user) {
// TODO Auto-generated method stub
return null;
}
public String sayHello(String name) {
// TODO Auto-generated method stub
return name;
}
}
　　3、启动服务（执行下列main函数）
public class TestService {
public static void main(String[] args) {
//服务地址
String address="http://localhost:8989/u";
Endpoint.publish(address， new HelloServiceImpl());
}
}
　　4、在浏览器上输入：http://127.0.0.1:8989/u?wsdl 看到以下信息：
