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最后一行是我抛出的异常信息.大致意思是:这个绝对路径(uri)不被web.xml应用程序在服务器容器(指的是我平台上的Tomcat7.0.11)上的部署.
我之前用的是MyEclipse8.5+JDK1.6+tomcat6.X,但是公司的服务器上是Tomcat7+JDK7,部署后运行除了bug现在重新架到Myeclipse9.0M1+JDK7+Tomcat7是调试的时候就这样了.
Jsp
<%@taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>忘前辈们多多指教,在下感激不尽!!!

Answer 1

在原来的环境(MyEclipse8.5+JDK1.6+tomcat6.X)上跑没有任何bug了的!

Answer 2

web.xml<taglib>
   <taglib-uri>http://java.sun.com/jsp/jstl/core</taglib-uri>
   <taglib-location>/WEB-INF/c.tld</taglib-location>
</taglib>

Answer 3

我的意思是不论做为<web-app>的子元素,还是独立标签web.xml都会报错.

Answer 4

上网查下<taglib>的用法吧
另外你的standard.jar,jstl.jar这两个jar是否放到了/WEB-INF/lib中
还有c.tld是否在WEB-INF目录中

Answer 5

web.xml<taglib>
<taglib-uri>http://java.sun.com/jsp/jstl/core</taglib-uri>
<taglib-location>/WEB-INF/c.tld</taglib-location>
</taglib

Answer 6

这么麻烦
在web-inf/lib目录下加上standard.jar和jstl.jar
jsp页面添加：
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>
应该就可以用了
