I've triple checked that the class files are there in WEB-INF/classes. I also tried putting in a jar in WEB-INF/ilb. I'm guessing that the Realm is still being loaded in a different class loader. I would guess the Realm is loaded in the "common" class loader, as defined at http://tomcat.apache.org/tomcat-6.0-doc/class-loader-howto.html.
