The articles were written before the final version of J2EE 1.3 was
completed.  The final version of the spec now mandates that Manifest
Class-Path: capability be for EJB JARs and WARs.  I liken the WEB-INF\lib
directory to be a place to store all libraries that should only be loaded by
the web app classloader while the manifest Class-Path: libraries are loaded
by the "EAR" classloader at a global level.

And, for posterity, the articles came first and the chapter came second ;-)

Subject: Re: Class-Path references in WAR archive manifest


Perhaps more germane to the question is the follow-up article at

http://www.onjava.com/pub/a/onjava/2001/07/25/ejb.html

which addresses class sharing among wars in an ear. Both articles are
drawn from the "Professional Java Server Programming J2EE 1.3 Edition"
chapter reproduced at

http://www.theserverside.com/resources/articles/J2EE-Deployment/chapter.
html.

The upshot is that if the app server is J2EE 1.3 compliant then a common
support jar declared as a dependency in an EJB module Manifest classpath
entry is available to all web apps in the ear. Nothing is said about war
Manifest classpath entries.
