为什么我的这个框架加了登陆判断后显示不出来呢？

在TOMCAT下显示不出来
哪个checkvalid.jsp页面如下：
<%@page contentType= "text/html; charset=gb2312 "%>
<%request.setCharacterEncoding( "gb2312 ");%>
<%@ page language= "java " import= "java.util.*,java.sql.* " pageEncoding= "gb2312 "%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN ">

<meta http-equiv= "keywords " content= "keyword1,keyword2,keyword3 ">
<meta http-equiv= "description " content= "This is my page ">
<!--

</head>
<body>
<!--验证用户是否经过有效检查 -->
<%
if( session.getAttribute( "login ") == null || !session.getAttribute( "login ").equals( "ok ")) {
response.sendRedirect( "index.html ");
}
%>
</body>
</html>
那位高手帮我看下
[解决办法]
看看显示的页面的源代码啊,是不是正确的页面~
[解决办法]
你把response.sendRedirect( "index.html ");换成out.print( " <script language= 'javascript '> location= 'index.html '; </script> \n ");
试试看呢
