I'm doing a java web application for a coursework, and it is required the use of JSTL library; so my questions are: does JSTL need to be configured on tomcat web.xml? If so, how can I configure it? I have already downloaded the jar file; where do I have to put it?

Thanks in advance!

不，您不必在web.xml中定义它。

您应该将jar放入WEB-INF / lib并在jsp中声明它。 就像是：

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %> <%@ taglib prefix="fmt" uri="http://java.sun.com/jsp/jstl/fmt" %> <%@ taglib prefix="fn" uri="http://java.sun.com/jsp/jstl/functions" %>

no, you don't have to define it in web.xml.

You should put the jar into your WEB-INF/lib and declare it in your jsp. something like:

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %> <%@ taglib prefix="fmt" uri="http://java.sun.com/jsp/jstl/fmt" %> <%@ taglib prefix="fn" uri="http://java.sun.com/jsp/jstl/functions" %>
