Finally I resolved the issue by myself. Below are steps:

1.Download jstl-1.2.jar and standard-1.1.2.jar from below links.

http://repo2.maven.org/maven2/javax/servlet/jstl/

http://repo2.maven.org/maven2/taglibs/standard/

2.Copy the two files into Tomcat lib folder.

3.Rename standard-1.1.2.jar to standard.jar.

The exception disappears then.

I create a jsp project with idea 2016 and the code of jsf is as following.

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

<html>
<head>
  <title>JSP 2.0 Expression Language - Implicit Objects</title>
</head>
<body>
<h1>JSP 2.0 Expression Language - Implicit Objects</h1>
<hr>
This example illustrates some of the implicit objects available
in the Expression Language.  The following implicit objects are
available (not all illustrated here):
<ul>
  <li>pageContext - the PageContext object</li>
  <li>pageScope - a Map that maps page-scoped attribute names to
    their values</li>
  <li>requestScope - a Map that maps request-scoped attribute names
    to their values</li>
  <li>sessionScope - a Map that maps session-scoped attribute names
    to their values</li>
  <li>applicationScope - a Map that maps application-scoped attribute
    names to their values</li>
  <li>param - a Map that maps parameter names to a single String
    parameter value</li>
  <li>paramValues - a Map that maps parameter names to a String[] of
    all values for that parameter</li>
  <li>header - a Map that maps header names to a single String
    header value</li>
  <li>headerValues - a Map that maps header names to a String[] of
    all values for that header</li>
  <li>initParam - a Map that maps context initialization parameter
    names to their String parameter value</li>
  <li>cookie - a Map that maps cookie names to a single Cookie object.</li>
</ul>

</body>
</html>

I got following error info.

After I remove below line, the exception disappears.

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

I downloaded jstl-1.2.jar and added it into external libraries of my project. The issue is still there. Anybody knows how to handle or debug the issue?

i am not sure which JAR file you need, but you need to make sure it's placed in web-inf/lib dir of your website

Did you add the jars to the artifact you deploy on the server?
