In any event, the author gives one method for including taglibs in jsp.
For example, for tiles you would use:
<%@ taglib uri="/WEB-INF/struts-tiles.tld" prefix="tilles" %>
This works, but requires you to put the tld files in your webapp under
WEB-INF. With a Servlet 2.3/JSP 1.2 or later container, this isn't
necessary.
But the current tiles docs say to use:
<%@ taglib uri="http://struts.apache.org/tags-tiles"; prefix="tiles" %>
...
1. Is the only way to determine the correct uri value to look it up
in the docs? (Is there any other way to know that the correct
value is "http://struts.apache.org/tags-tiles"; ?)
The final answer is in the tld itself, which you can find inside the
struts-tiles jar, or in svn:
http://svn.apache.org/repos/asf/struts/struts1/trunk/tiles/src/main/resources/META-INF/tld/struts-tiles.tld
The uri should match there in the tld and in your <%@ taglib > directive.
2. How does that really work ? I know that nothing ever actually
connects to http://struts.apache.org, so how does that value get
mapped to the correct jar file under WEB-INF? Are all the jar
files checked until one with a matching tag is found?
According to Craig, it's magic. :)

I'm hazy on the specifics, but I think all the jars get scanned when
the webapp starts, and that it looks in META-INF and below. Any tlds
it finds are then available to the webapp.
