各位大神，本人小白，初学jsp。在做完连接数据库并将数据显示到页面上后，页面的所有样式都无效了，以下是我的代码。
<%@page language="java" import="java.util.*" pageEncoding="utf-8"%>
<%@page import="java.util.ArrayList"%>
<%@page import="org.cz.bean.Select"%>
<% /*如果还未登录系统*/
if (session.getAttribute("user")==null || session.getAttribute("user")=="")
out.println("<script>alert('未登录系统！');top.location.href='../login.jsp';</script>");
%>
<%-- <%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>
--%>
