Follow the usual debugging steps:
  • Be sure that your servlet is in a package other than the default.
  • Make sure that your servlet is properly mapped to a URL in the deployment descriptor.
  • Make sure that you use the mapped URL properly when addressing the servlet. Don't forget to include the context path.
