Tomcat 4.1 and JSP taglibs

The problem:

I just spent over an hour trying to figure out why I kept getting:
org.apache.jasper.JasperException: This absolute uri (http://java.sun.com/jstl/core) cannot be resolved in either web.xml or the jar files deployed with this application.

Cause:
  1. I was using version 1.1.0 of standard.jar and jstl.jar with 4.1.30 tomcat.
  2. I had an invalid web.xml.
Solution:
  1. Use 1.0 JSTL:
  2. Make sure web.xml is 100% valid, otherwise jasper does not seem to find any taglibs.
