Classloader problem using WCK

I have successfully installed WCK (Slide 2.2), and I have
created a custom
implementation for SessionAuthenticationManager which gets
invoked just
fine.

 

My problem is that my implementation uses classes that are
defined in
tomcat/shared/lib, and these classes do not seem to be
accessible to the
slide webapp.

 

Can anyone explain why classes from "shared/lib"
are not available from the
slide ClassLoader?
