How to resolve : Can not find the tag library descriptor for “http://java.sun.com/jsp/jstl/core” [duplicate]

Answer 1

As @ace mentioned you will need the jstl.jar in your project, so if you are using maven, you could add this dependency:

<dependency>
    <groupId>jstl</groupId>
    <artifactId>jstl</artifactId>
    <version>1.2</version>
</dependency>

Source: http://mvnrepository.com/artifact/jstl/jstl/

Hope it helps.

EDIT: Most of servers already have this dependency, if you add it using maven it may cause version conflicts (like Method/ClassNotFoundException) if you don't configure the server well, so it's better set a target server for your project, as @willix mentioned.

Answer 2

It has nothing to do about <%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>.

Just go to project and right click then project menu -> Clean the project error will definitely remove and update maven .

Answer 3

You have to write as

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

Make sure you have jstl-1.0 & standard.jar BOTH files are placed in a classpath

Answer 4

Add both javax.servlet.jsp.jstl-api-1.2.1.jar and standard-1.1.2.jar

Answer 5

It will work perfectly when you will place the two required jar files under /WEB-INF/lib folder i.e. jstl-1.2.jar and javax.servlet.jsp under /WEB-INF/lib folder.

Hope it helps. :)

Answer 6

paste below two jar in your /WEB-INF/lib folder and then go to project properties and go to add jar and select these two jars then click Ok, Ok

standard.jar, jstl-1.0.2.jar
