1，异常处理

package com.yangw.soap.service;

public class UserException extends Exception {

    public UserException() {
        super();
    }
    public UserException(String message, Throwable cause) {
        super(message, cause);
    }
    public UserException(String message) {
        super(message);
    }
    public UserException(Throwable cause) {
        super(cause);
    }   
}

　　为login()方法增加抛异常

package com.yangw.soap.service;

import javax.jws.WebParam;
import javax.jws.WebResult;
import javax.jws.WebService;

//说明该接口是服务接口
@WebService
public interface IMyService {
　　　　......
     @WebResult(name="user")
     public User login(@WebParam(name="username")String username,
             @WebParam(name="password")String password) throws UserException;   
　　　　...... 
     
}

package com.yangw.soap.service;

import java.util.ArrayList;
import java.util.Date;
import java.util.List;

import javax.jws.WebService;

//说明该类是服务接口的实现类
@WebService(endpointInterface="com.yangw.soap.service.IMyService")
public class MyServiceImpl implements IMyService {

......
    @Override
    public User login(String username, String password) throws UserException{
        for(User user:users){
            if(user.getUserName().equals(username)&&user.getPassword().equals(password)){
                return user;
            }
        }
        throw new UserException("用户不存在!");
    }

......

}
