Can't you use HttpServletRequest.getRemoteUser(), getUserPrincipal()?
http://java.sun.com/j2ee/1.4/docs/api/javax/servlet/http/HttpServletRequest.html
getRemoteUser()
Returns the login of the user making this request, if the user
has been authenticated, or null if the user has not been authenticated.
java.security.Principal getUserPrincipal()
Returns a java.security.Principal object containing the name
of the current authenticated user.
