the method will return null if the user is not authenticated. There is also the
method
java.security.principal user = HttpServletRequest.getUserPrincipal() which
returns the current user (if logged in).
have a read of the "security" chapter of the servlet spec (chapter 11 in 2.2,
chapter 12 in 2.3). This tells you how to configure your web app to require
authentication to access certain resources.
