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

To resolve this issue:

1. 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.

2. 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"%>

Just check our own JSTL wiki page for the proper download links and crystal clear installation instructions.

Put your mouse above the [jstl] tag which you put on the question yourself until a black box shows up and click therein the info link.

Then scroll a bit down to JSTL versions information until you find download link to JSTL 1.2 (or 1.2.1).

Finally just drop exactly that file in webapp's /WEB-INF/lib.

This way the taglib declaration must not give any errors anymore and the JSTL tags and functions should just work.

I just want to share my experience. I have same problem about jstl using maven. I resolved it by adding two dependency.

    <dependency>        <groupId>javax.servlet</groupId>        <artifactId>servlet-api</artifactId>        <version>2.5</version>    </dependency>    <dependency>        <groupId>jstl</groupId>        <artifactId>jstl</artifactId>        <version>1.2</version>    </dependency>
