Hi using
eclipse juno, dynamic web project
apache Tomcat v7.0 (which has its own jstl-1.2.1.jar)
I get this error
javax.servlet.ServletException: java.lang.NoClassDefFoundError: javax/servlet/jsp/jstl/core/LoopTag
org.apache.jasper.servlet.JspServlet.service(JspServlet.java:343)
javax.servlet.http.HttpServlet.service(HttpServlet.java:722)
when I try running this jsp code
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Insert title here</title>
</head>
<body>
<c:forEach var="test" items="a,b,c">
${test}
</c:forEach>
</body>
</html>
it seams not to be seeing the javax.servlet.jsp.jstl.core.LoopTag class that is in the jar
I have read something about filters blocking javax.servlet files
any help would be greatly appreciated
ok I think I have found the solution
javax.servlet.jsp.jstl-1.2.1.jar
does not contain the javax.servlet.jsp.jstl.core classes
jstl-1.2.jar needs to be added as well

Full Stack Java developer - Java + JSP + Restful WS + Spring The <c:forEach> tag is a commonly used tag because it iterates over a collection of objects. The <c:forTokens> tag is used to break a string into tokens and iterate through each of the tokens.
The <c:for each > is an iteration tag used for repeating the nested body content for fixed number of times or over the collection. These tag used as a good alternative for embedding a Java while, do-while, or for loop via a scriptlet.
javax.servlet.jsp.jstl-1.2.1.jar doesn't contain the javax.servlet.jsp.jstl.core classes. Be sure to add jstl-1.2.jar as well.

If you are using maven, add
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>jstl</artifactId>
<version>1.1.2</version>
</dependency>
to your pom.xml

If you want to use forEach you should add two libraries to WEB-INF/lib of your project: Impl: taglibs-standard-impl-1.2.5.jar Spec: taglibs-standard-spec-1.2.5.jar
