JSTL 1.0 and 1.1 URI

It's a bit confusing for some developers why EL doesn't work in JSTL tags where they think it should've work and it turns out the culprit is the taglib uri.

JSTL 1.0 URI is http://java.sun.com/jstl/core
JSTL 1.1 URI is http://java.sun.com/jsp/jstl/core

So instead of using 1.0, it is better to use 1.1.

Don't forget to put standard.jar and jstl.jar in your WEB-INF/lib.
