This is due to the fact that Windows is not case sensitive on filenames, but
Java is.  From the Java perspective, "Simpleservlet" and "SimpleServlet" are
not the same, even though Windows isn't smart enough to know that.  By the way,
this will affect any reference to a class in any Java program on Windows, not
just servlets under Apache JServ.
