Question

我已经摔跤了好几天。我有一个简单的教程项目，每当我将以下指令添加到我的简单JSP中时，页面都无法加载：

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

来自Tomcat的错误

Oct 12, 2015 3:23:49 PM org.apache.catalina.core.StandardWrapperValve invoke
SEVERE: Servlet.service() for servlet [offers] in context with path [] threw exception [The absolute uri: http://java.sun.com/jsp/jstl/core cannot be resolved in either web.xml or the jar files deployed with this application] with root cause
org.apache.jasper.JasperException: The absolute uri: http://java.sun.com/jsp/jstl/core cannot be resolved in either web.xml or thejar files deployed with this application

我改变了web.xml：

<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
     xmlns="http://java.sun.com/xml/ns/javaee"
     xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
     id="WebApp_ID" version="2.5">

这就是诀窍。

为什么JSTL会导致IntelliJ 14 Ultimate，Tomcat 7，Spring 4.2.1，OSX El Capitan出现问题？
