Tomcat 4.1.24, Classloader problems

Hi all, Having a weird problem that is driving me nuts. In the past week, every time I update a supporting class (Not a servlet or JSP) and refresh my page, I get all kinds of null pointer exceptions and must log out and back into my application or restart Tomcat. This is a pain in development.
