Hi, Hmm... I'd guess it should go in the same repository as the normal WebappLoader, which is $CATALINA_HOME/server/lib. $CATALINA_HOME/server/classes should be functionally equivalent for unpacked classes, so it's strange you get the CNFE when you put your loader there. Try packaging your loader in a jar file and putting that jar in server/lib.
