如何显示包含来自jsp的javascript的外部网站？
我必须在jsp中嵌入一个HTML文件。此HTML文件是动态的，必须根据用户请求下载。我尝试的是将html下载到一个目录中，然后从jsp中显示它 因为我尝试的方法之一是这样的：如何显示包含来自jsp的javascript的外部网站？,java,html,jsp,servlets,Java,Html,Jsp,Servlets,我必须在jsp中嵌入一个HTML文件。此HTML文件是动态的，必须根据用户请求下载。我尝试的是将html下载到一个目录中，然后从jsp中显示它 因为我尝试的方法之一是这样的： public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { response.setContentTy

<%@ include file="/web/external.html" %>
还是不走运。不使用iframe的最佳方法是什么？（我计划呈现的网站不支持iframe）上述问题的解决方案是在jsp中添加以下内容：
<%@ taglib uri = "http://java.sun.com/jsp/jstl/core" prefix = "c" %>
<html>
<head>
<title> Tag Example</title>
</head>
<body>
<c:import var = "data" url = "${page}"/>
<c:out value = "${data}" escapeXml="false"/>
</body>
</html>
使用了
c标记库escapeXml=“false”
