The best way to debug servlets that I have found is to make it so there is as little code as possible in the servlet itself, and as little code as possible which depends on "non-mockable" Servlet API classes. I typically have just enough code in the servlet to extract the parameters from the Request and the Writer from the Response, ...

If the logging statements and your brain are not sufficient then it is because one of them is deficient.

Otherwise you don't understand your own code properly.
