Sun JSTL taglib declaration fails with “Can not find the tag library descriptor” [duplicate]

Question

To resolve this issue:

The jstl jar should be in your classpath. If you are using maven, add a dependency to jstl in your pom.xml using the snippet provided here. If you are not using maven, download the jstl jar from here and deploy it into your WEB-INF/lib.
Make sure you have the following taglib directive at the top of your jsp:
```
 <%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
```
