1、错误描述
2、错误原因
JSTL core库的有两种taglib伪指令, 其中RT库即是依赖于JSP传统的请求时属性值, 而不是依赖于EL来实现(称为EL库.JSP2.0将支持EL)
JSP中使用<%@ taglib uri=http://java.sun.com/jstl/core prefix="c"%>在2.3版本都可以,在2.4就不行了
3、解决办法
将以下一句：
<%@ taglib prefix="c" uri="http://java.sun.com/jstl/core" %>
改成
<%@ taglib prefix="c" uri="http://java.sun.com/jstl/core_rt" %>
就可以了
