刚好又一个现成的
这是welcome页面
<%@ page contentType="text/html; charset=gb2312" language="java" import="java.sql.*" errorPage="" %>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312" />
<title>题1和2</title>
</head>
<body>
<center>
<form action="help.jsp" method="post">
<table>
<tr>
<td>
用户名：
</td>
<td>
<input type="text" name="user" />
</td>
</tr>
<tr>
<td>
密码
</td>
<td>
<input type="password" name="password" />
</td>
</tr>
<tr>
<td align="center">
<input type="submit" value="提交" />
<input type="reset" value="重置" />
</td>
</tr>
</table>
</form>
</center>
</body>
</html>

<%@ page contentType="text/html; charset=gb2312" language="java" import="java.sql.*" errorPage="" %>
<meta http-equiv="refresh" content="5" ; url="ques12.jsp">
<p align="center">

<br />

</p>
<center>
<%!int number = 1;%>
<%
number ++;
%>
<%="如果你看见括号内的数字在增加表示页面刷新成功了（"+number+")成功了！！！"%>
<font color="#FF0000">页面刷新频率为5s/次</font>
</center>
