Re: proper taglib declarations

[Michael McGrady]

The question is not which is proper, Brian.  I think that both these ways 
of doing this just confuse new people and are very bad ideas.  What I do is 
this:

        <%@ taglib uri='struts-bean'    prefix='bean' %>
This should make it clear that the "uri" is not a "uri" at all.  Most 
supposed "url" and "uri" are not really those things at all in web 
work.  This is a very fruitful way of confusing newcomers and feeling 
superior.  ///;-)

The value of the uri is simply the value you have put in your web.xml for 
the tld.  For example, my bean taglib has the following tags in the web.xml.

  <taglib>
    <taglib-uri>struts-bean</taglib-uri>
    <taglib-location>/WEB-INF/tld/struts-bean.tld</taglib-location>
  </taglib>
I could have put anything in the "uri" that did not conflict with other 
such "uri".  The "uri" is really just a name which references the location 
of the tld for the tag.  There probably is a good reason why they did not 
have "name" be the tag instead of "uri", but it is not interesting enough 
for me to investigate.

Hope this helps.  The answer is that there is no "proper" way to do this 
and the usual ways are confusing to new people.  I would venture to guess 
your inquiry is a direct result of the fact that other people have used 
names for the locations that appear falsely to be syntactically related to 
locations when in fact they are a meaningless semantic overlay of a 
location that merely confuses people.

I've seen two different ways to declare taglibs in jsp files:

<%@ taglib prefix="fmt" uri="http://java.sun.com/jsp/jstl/fmt"; %>
<%@ taglib prefix="html" uri="/WEB-INF/lib/struts-html-el.tld" %>

What is the difference between referencing http://blah <http://blah/>  blah
and /WEB-INF/blah blah? Are they interchangeable? How do I know when to use
one over the other?  Also, how should they be specified in the web.xml file,
where I have also seen multiple syntaxes?

Thanks,
