Hello Will,Micael
The way webapps work with classloaders is opposite that of the normal
classloader precedence. The WebappClassloader looks in its own
classloader for libraries first before looking at parent classloaders.
What normally happens is that the parent classloader is queried first
for libraries and if they don't exist there, then they are loaded from
those further down the hierarchy (closer to the current classloader).
As far as the order goes, here is the WebappClassloader order:
WEB-INF/classes
WEB-INF/lib
class files in the WEB-INF/classes dir are *always* loaded first.
