[吃小妖的星星]

老师布置的题目，基本写好，可是welcome.jsp不会写，不知道时间该怎么显示出来，可能LoginServlet.java就写得不对，应该不难，求指导

LoginServlet.java：

package com.demo;
import java.io.*;
import java.util.*;
import java.text.SimpleDateFormat;
import javax.servlet.*;
import javax.servlet.http.*;

public class LoginServlet extends HttpServlet {
public void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {

String username = request.getParameter("yonghu");
String password1 = request.getParameter("mima");
Date date = new Date();
SimpleDateFormat sdf = new SimpleDateFormat("yyyy年MM月dd日");

String location="";

if(username.equals("admin")&&password1.equals("admin"))
{
String s = sdf.format(date);
location = "/welcome.jsp";
RequestDispatcher dispatcher = request.getRequestDispatcher(location);
dispatcher.forward(request, response);
}
else
{
response.sendRedirect("register.html");
}
}
}
