Taglib URI

Question

Hi
I'm developing portlets with JAVA EE 5, Tomcat 5.5.x and Spring Framework 2.0.
JSP + JSTL are used for views.
In my jsp pages I have a line
<%@ taglib prefix="c" uri="http://java.sun.com/jstl/core" %>
which work fine and I can use the core taglib and its tags.
However, if I read the Java EE 5 manual at http://java.sun.com/javaee/5/docs/tutorial/doc/JSPIntro9.html#wp73319 (at the end) it says that:
The absolute URIs for the JSTL library are as follows:
* Core: http://java.sun.com/jsp/jstl/core
This URI doesn't work for me. Is this a problem with Tomcat 5.5.9 or am I using wrong jar somewhere? I think jstl.jar is the one to look for - which version should I use and how do I know which version I have?
Error:
Servlet.service() for servlet jsp threw exception
org.apache.jasper.JasperException: /WEB-INF/jsp/index.jsp(1,1) The absolute uri: http://java.sun.com/jsp/jstl/core cannot be resolved in either web.xml or the jar files deployed with this application
with best regards Fredrik

The difference is between JSTL1.0 and JSTL1.1
<%@ taglib prefix="c" uri="http://java.sun.com/jstl/core" %> = JSTL1.0
<%@ taglib prefix="c" uri="http://java.sun.com/jstl/jsp/core" %> = JSTL1.1
You can check the version by looking at the file Manifest.mf in the META-INF file of standard.jar or jstl.jar
You most probably have JSTL1.0 installed.
