What Is JSTL Core Library

This section describes the JSTL Core library, represented by http://java.sun.com/jsp/jstl/core in JSTL 1.2.

What Is JSTL Core Library? JSTL Core Library is the main library of JSTL (JSP Standard Tag Libraries). JSTL Core library is defined with the following URIs:

http://java.sun.com/jsp/jstl/core - JSTL 1.2
http://java.sun.com/jsp/jstl/core - JSTL 1.1
http://java.sun.com/jstl/core - JSTL 1.0

If you want to use any tags defined in the JSTL core library, you need to declare an XML namespace using the URI listed above:

<!-- Default JSP Page format -->
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>

<!-- XML JSP Document format -->
<jsp:root xmlns:c="http://java.sun.com/jsp/jstl/core" ...>

JSTL Core provides the following basic tags (also called actions):

<c:out value="..."/>
<c:set var="..." value="..."/>
<c:if test="...">body</c:if>
<c:forEach items="...">body</c:forEach>
<c:forTokens items="..." delims="...">body</c:forTokens>
