JSP---JSTL configuration

About configuration issues with the JSTL standard tag library in eclipse

My version of Eclipse is: Version:neon.3 release (4.6.3)

With the 1.8.0_121 of the Jre,tomcat 9.0,

The above version is currently near the latest.

First, you search online. Download three jar files: Jstl.jar, Stander.jar, and Xalan.jar files

Then put this three jar file in the Lib folder under WebContent in the Web project

Also put this three jar file in the Lib folder in Tomcat.

In the JSP file, you need to import the core tag library of Jstl using a taglib directive

<%@ taglib uri= "Http://java.sun.com/jsp/jstl/core" prefix= "C"%>

<c:out value= "Hello world!"/>

If "Hello World" is successfully exported, the configuration succeeds
