JSTL startup question

Hi - I wonder if anyone can shed any light on this.

I have started to read JSTL in action by Shawn Bayern.

I have set up Tomcat5 and mysql on my XP machine and it all works fine - so
I have my development environment.

I have downloaded and published the JSTL1.1.2 zip - and that all seems to
work fine.

I have taken the jars from the un-packed web-app and they work fine.

But..................

When I read the book - it states that I should have <%@ taglib
uri="http://java.sun.com/jstl/core" prefix="c" %>

in the page  which I have and it works

But.................

In the download document (which I expect to be more up-to-date) it states
that I should have <%@ taglib uri="http://java.sun.com/jsp/jstl/core"
prefix="c" %>

(Additional jsp in the path).

And................

Only the former works...

Would anybody be so good as to comment.

Kind regards

Kevin
