Upgrade Spring MVC Controller classes to use annotations:
http://blog.interface21.com/main/2007/11/14/annotated-web-mvc-controllers-in-spring-25/

Form Controllers which extend BaseFormController (and in turn, Spring's SimpleFormController) can make use of the @RequestMapping annotation to define their request mappings:
 org.appfuse.web.controller.FileUploadController
 org.appfuse.web.controller.SignUpController
 org.appfuse.web.controller.UserFormController

Other controllers should be rewritten to be annotation-based controllers, with the @Controller annotation:
 org.appfuse.webapp.controller.PasswordHintController
 org.appfuse.webapp.controller.UserController

Tutorials should also be updated.
