Answer 1

http://java.sun.com/jsp/jstl/core cannot be resolved in either web.xml or the jar files deployed with this application 貌似你没把jstl使用的jar文件引入到项目中
myeclispe7.0的话直接左侧 【项目】 【右键】 【MyEclipse】 【add JSTL】或者 【项目】 【右键】 【Bulid path】  【libraries】 【add external jars】找到你下的jstl的两个jar文件

Answer 3

可是我加了jstl.jar和standard.jar还是出现了错误呀

Answer 4

加了之后要重新发布下项目
跑到tomcat安装目录下 webapps中你发布项目下的lib文件夹里看看这两个jar在不在
