如何跳出框架？

看我的out.jsp

 

<%@ page import="java.sql.*,com.lssp.team.*,java.util.*"%>
<%@ page language="java" pageEncoding="utf-8"%>
<%@ page contentType="text/html;charset=utf-8"%>


<%
session=request.getSession();
session.invalidate();

 %>
 out.println( " <script> parent.location.href='../webs/index.jsp' </script> ");
