OK, four things when dealing with ANY tag library:
1. PLACE JAR FILES
Place JAR files that hold implementation of the tag library in a directory where
Tomcat will pick it up. Either make it "WEB-INF/lib/" (private) or
"${CATALINA_HOME}/shared/lib" (all web-apps will have access to it). You could place
it in "${CATALINA_HOME}/common/lib", but I don't see the point in Tomcat having access
to those JARs. There was a discussion recently naming pros/cons of each choice
(Craig), so look up the archives.
2. PLACE TLD
Place TLD files (Tag Library Descriptor) in either "WEB-INF/" or (if I recall
correctly) "WEB-INF/taglibs/". The first placement will require for "location" in
"web.xml" file to be absolute: "/WEB-INF/<name>.tld", while the second will allow for
relative links: "<name>.tld"
3. DECLARE TLD IN WEB.XML
This part you've already seen.
<taglib>
<taglib-uri>http://java.sun.com/jstl/core</taglib-uri>
<taglib-location>/WEB-INF/c.tld</taglib-location>
</taglib>
4. DECLARE TLD USAGE IN JSP
This you've seen
<%@ taglib uri="http://java.sun.com/jstl/core"; prefix="c" %>
The prefix is up to you.
Nix.
