The absolute uri: http://java.sun.com/jsp/jstl/core cannot be resolved in either web.xml or the jar

1（未解决-依旧报同样的错误）.加上两个jstl1.2.jar包和stardard1.1.2.jar之后没有解决（Deployment assembly ————》Add——》java build path Entries——>Maven Dependices将maven加载的jar包更新到lib里面）

2（未解决-依旧报同样的错误）.web.xml上加

1. <taglib>  
2.     <taglib-uri>http://java.sun.com/jstl/fmt</taglib-uri>  
3.     <taglib-location>/WEB-INF/fmt.tld</taglib-location>

3（解决）.在tomcat本地的的lib里直接加上jstl和stardard的jar包
