为什么我的jsp页面无法使用https而不是http解决包含jsp taglib的问题？

Question

由于公司安全更新，我最近不得不将Web应用程序中的所有导入内容从http更新为https。但是我的jstl导入将不起作用。这是一个例子。我所做的唯一更改是添加了s。顶行是它的样子，底线是现在的样子：

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
<%@ taglib prefix="c" uri="https://java.sun.com/jsp/jstl/core"%>

我希望这能正常工作，因为the tutorial from this link会以我尝试的确切方式使用https。复制/粘贴，以防链接失效：

<%@ taglib uri="https://java.sun.com/jsp/jstl/core" prefix="c" %>

但是我的Web应用程序服务器现在抛出此异常：

关于为什么这行不通的任何想法？或如何解决？

taglib的URI只是一个标识符，它不用于获取任何资源。它们在JSTL规范中定义：

因此URI必须完全是这样。
