global resources

[Christian J. Dechery]

I can't seem to get my classes as global. 
 
I want them to be acessed by all applications... so I placed it under 
$CATALINA_HOME/classes and $CATALINA_HOME/lib right?
 
Well... when I do that, either two things happen: it doesn't find the classes and 
nothing works, or it gives me a crazy error regarding ServletException and some cast 
error.
 
any clues?
