Your problem is due to the servlet class not being in a package.
ALL classes used in servlets should be in a package and stored under classes according to the package.
Older versions of Tomcat and older books depended on the "invoker" servlet to find classes not in a package - this was a very very very bad idea and was abandoned years ago. The original designers thought it would make things easier for beginners but it has caused untold trouble.
