Development environment tomcat8.5 jdk1.8.1 eclipse photo

<%@ taglib uri=” http://java.sun.com/jsp/jstl/core ” prefix=”c” %>

After adding the above import information to the JSP page, an error will be reported

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

For specific solutions, now put jstl.jar and standard.jar in the Tomcat/lib Library folder, copy a standard file, unzip it, find the WEB-INF/c.tld file, and copy it to the WEB-INF directory of the project file to solve the error reporting problem
