想用下jstl，用法如下：
报错结果：rg.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

web.xml配置如下：

不知道为什么web.xml :<taglib>

<taglib-location>/WEB-INF/tlds/fmt.tld</taglib-location>
</taglib
起始处报错，程序运行报错：rg.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
我想是配置问题，大家都遇到过没有啊？？

用jstl标签库不用配置web.xml呀,直接将jstl.jar和standard.jar拷到WEB-INF/lib下面,再将对应的tld文件放到WEB-INF/下面.在jsp页面中可以直接引用 <%@taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>.
