当我<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
用于我的 struts 1.3.10 项目时,它会引发以下异常:
org.apache.jasper.JasperException: 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

然后,当我将其更改为
<%@ taglib uri="http://java.sun.com/jstl/core_rt" prefix="c" %>
它工作正常。我想知道这两者之间有什么区别,以及为什么在我尝试使用<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
. 顺便说一句,我使用服务器 apache-tomcat-7.0.42。请帮我。
