HTML代码：

<head>
   <title>登录验证</title>
  </head>
 <body>
    <form action="index.jsp" method="post" >
        <table align="center">
        <tr>
            <td><img src="Snap1.jpg"><div style="position:absolute; left: 650px; top: 216px; width: 356px;">
                <table align="right">
                    <tr>
                        <td align="right">用户名：&nbsp;</td>
                        <td height="27"><input type="text" name="u_name" size="20"/><br></td>        
                    </tr>
                    <tr>
                        <td align="right">密码：&nbsp;</td>
                        <td height="27"><input type="password" name="u_pswd" size="20"/><br></td>        
                    </tr>
                    
                    <tr>
                        <td>
                            <div style="position:absolute; left: 200px; top: 80px; width: 356px;">
                                <input type="image" src="login.gif" width="101" height="22" border="0" name="submit" value="提交" />
                            </div>
                        </td>        
                    </tr>
                    
                </table>
                    </div>
                </td>
            </tr>
        </table>
    </form>
</body>

JSP判断代码：

  <body>
        <%
            request.setCharacterEncoding("utf-8");
            String user=request.getParameter("u_name");
            String pwd=request.getParameter("u_pswd");
         %>
         <%
             if(user.equals("lucky") && pwd.equals("123456")){
        out.print("你好,"+user+"!");
        //登陆成功
        request.getRequestDispatcher("MyJsp.jsp").forward(request, response);
    }else{
        //重新登录    
        response.sendRedirect("loginJsp.jsp");
        
        }
    %>

  </body>

页面代码：

<body>
