Hello Will, 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.
