Getting JSTL to run within Tomcat and Eclipse

Question

I've been trying to get this to run, but I can't. I'm using Eclipse Galileo, Tomcat 5.5.23 and have several JSTLs around. My latest try was to use the GlassFish jar file "jstl-impl-1.2.jar". I placed it in Tomcat's shared lib, added it as external jar into my Eclipse project and exported it.

Could anybody tell me, which jars to load in which folder and how to tell it to load in Eclipse?

Answer 1

It's very simple to include jstl in your projects, what I do is:

1. Download jstl-1.2.jar (JSP 2.1 containers only i.e. Tomcat 6, otherwise jstl-1.1.jar) from http://repo1.maven.org/maven2/javax/servlet/jstl/1.2/
   or
   the interfaces (javax.servlet.jsp.jstl-api-1.2.1.jar) from http://search.maven.org/#browse|707331597 and the actual implementing classes (javax.servlet.jsp.jstl-1.2.2.jar) from http://search.maven.org/#browse%7C-1002239589.

2. Copy to your project's WEB-INF/lib directory

3. Include the following tags in yours jsp's:
   • <%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
   • <%@ taglib uri="http://java.sun.com/jsp/jstl/fmt" prefix="fmt" %>
   • <%@ taglib uri="http://java.sun.com/jsp/jstl/functions" prefix="fn" %>
   • <%@ taglib uri="http://java.sun.com/jsp/jstl/sql" prefix="sql" %>

As for eclipse I need to know if your using any framework plugin, I use MyEclipse and it does it automatically for me.

Answer 2

Another method is shown here https://stackoverflow.com/tags/jstl/info

In short, download jstl.jar from here:

http://download.java.net/maven/1/jstl/jars/jstl-1.2.jar

and drop it in your WEB-INF/lib dir

and add the line:

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

in your jsp file.

(don't forget to do F5 and clean and build after that)
