    给你一个很简单的。表结构：(表名users)用户名（id），密码（password）：(都是varchar)我用的是数据库sql2000。
    登陆：（login.jsp）
    <%@ page contentType = "text/html;charset = GB2312" %>
    <html>
    <head>
    <meta http-equiv="Content-Type" content="text/html; charset=gb2312">
    <title>登录页面</title>
    </head>
    <body>
    <form action="validate.jsp" method=post>
              <p align=left><font color=#666666>用 户</font> 
                <input maxlength=10 name="id" size=10><font color=#666666>密 码</font> 
                <input maxlength=10 name="password" size=10 type=password>
                <input id=submit13 name=submit1 type=submit value=登录>
              </p>
            </form>
    </body>
    </html>
    判断页面：(validate.jsp)
    <%@ page import="java.sql.*"
       contentType="text/html; charset=GB2312" %>

    <head>
