Hello,
I'm trying to implement and register a new WebappLoader implementation with Tomcat
5.0.19. I've created a subclass of the standard WebappLoader class. In addition, I
have added the Loader element to my Context element with my new class name specified.
When starting the server, I get a ClassNotFound exception when it attempts to do a
Class.forName for my class in the CreateLoaderRule.begin method. I've tried my class
in <tomcat-root>/common/classes and also in <tomcat-root>/server/classes with no luck.
Can anyone offer any idea what I might be doing wrong and how I might solve the
problem?
Thanks,
Craig
