今天在使用JSP,引入<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>时报错。

报错信息:Failed to load or instantiate TagLibraryValidator class: org.apache.taglibs.standard.tlv.JstlCoreTLV

这是因为standard.jar的原因,在tomcat的lib路径下加入standard.jar包,就解决了。


在加入此jar包之后,又报了一个错。

报错信息:java.lang.ClassNotFoundException: javax.servlet.jsp.jstl.core.ConditionalTagSupport

这是因为还缺少jstl.jar包,同样的在tomcat的lib路径下加入jstl.jar包。
