Question

我在JSP页面中遇到CSS问题。

CSS文件未在任何页面中加载。

我有这个JSP页面，它是学生的注册表。

我有一个页面正常工作，但该页面没有来自我的数据库的信息。

其余页面包含一些行和数据库中的一些数据。

我真的不知道问题出在哪里，所以我需要你的帮助:(

学生表：

添加＆＃34; ..＆＃34;走到你所有的道路上，

<link href="../Style/style.css" rel="stylesheet">

Answer 2

试试这个：

 try {
      int idop=Integer.parseInt(op);
      int tel=Integer.parseInt(telephone_etudiant);

      SimpleDateFormat simpledate=new SimpleDateFormat("yyy-MM-dd");
      Date birthdayDate = simpledate.parse(date_naissance_etudiant);

      Optionn opt = new Optionn();
      opt = (Optionn) session.get(Optionn.class,idop);

      Etudiant etudiant=new Etudiant(opt,nom_etudiant,prenom_etudiant,niveau_etudiant, mot_de_pass_etudiant,num_inscription_etudiant,birthdayDate,adresse_etudiant,email_etudiant,tel);

     session.save(etudiant);
     session.getTransaction().commit();
     session.close();

    RequestDispatcher dispatcher = request.getRequestDispatcher("Jsp/home.jsp");
        dispatcher.forward(request, response);



   } catch (ParseException ex) {
        Logger.getLogger(reg_agent.class.getName()).log(Level.SEVERE, null, ex);
   }

Answer 3

尝试使用绝对路径

<%
String path = request.getContextPath();
String serverPath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort();
String basePath = serverPath + path+"/";
%>
<base href="<%=basePath%>"/>
