Answer 1

For installing JSTL, all you need are the jar files in the web-inf/lib directory.
- No entries in web.xml
- no tld files lying around
- no problems!
I think you may have a versioning problem here.
What version of Tomcat are you using?
With JSP1.2 (eg Tomcat 4), you should be using JSTL1.0. <%@ taglib prefix="c" uri="http://java.sun.com/jstl/core" %>
With JSP2.0 (eg Tomcat 5), you should use JSTL1.1. <%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
Note the difference in the URIs. - the second one includes a /jsp
Currently you are using the URI for JSTL1.0, but you look to have the tld from JSTL1.1. If you are using a JSP1.2 container, I don't think it could read this tld file, hence the error.
Try installing the correct version of JSTL, properly (ie as they tell you in the readme file) and it should all work.
