我在 Tomcat 的根文件夹下有 Jsp 文件，我想包含另一个放在 webapps 文件夹下的 jsp 文件。当我尝试以下代码时
<%@page contentType="text/html" pageEncoding="UTF-8"%>
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>JSP Page</title>
</head>
<body>
<h1>Hello World!</h1>
<jsp:include page="../docs/index.html"/>
</body>
</html>
我收到以下异常
HTTP Status 500 - An exception occurred processing JSP page /trail.jsp at line 16
type Exception report
message An exception occurred processing JSP page /trail.jsp at line 16
description The server encountered an internal error that prevented it from fulfilling this request.
