hi,
By http://tomcat.apache.org/tomcat-5.5-doc/class-loader-howto.html
Shared is the parent classloader of webapp.
AFAIK the consequence of this in that a class loaded from webapp
classloader
can see other classes (whenever they come from shared, webapp or
common),
but the reverse is not true, and could lead to ClassNotDef or
ClassNotFound
exeption unless some classloader hack are performed ...
This sentence:
"For classes and resources that must be shared across all web
applications, place unpacked classes and resources under
|$CATALINA_BASE/shared/classes|, or place JAR files containing those
classes and resources under |$CATALINA_BASE/shared/lib|."
is exactly what I'm referring to, but I've never gotten this to work.
My webapps can't see classes in the .jar that is in the shared/lib
folder; I get the ClassNotFound errors when I try.

From what I've read in the Tomcat 5.5 docs, I should be able to deploy
a .jar that is shared across multiple webapps on Windows by putting it
in the (tomcat)/shared/lib folder, but I've never gotten that to work.
I've always had to put that jar in the web-inf/lib folder of each of the
webapps that need it, in order for them to be able to use it. Why is
that? Is there something I'm missing about deploying shared jars? The
wasted disk space doesn't matter, but the hassle of putting the same
.jar file in multiple different places does...
Any help or explanations would be appreciated!
