Sorry by my English.

How I can guess login and password strings of an user, from error page (JSP)
using "Form Based Authentication of Tomcat"?

I need know it to lock the count each 3 error tries (if login is ok but
password is bad, insteed).

Methods 'getRemoteUser', 'isUserInRole' and 'getUserPrincipal' of
HttpServletRequest interface have this result: If no user has been
authenticated, returns null, false and null respectly. For this reason, they
aren't utils for me.

If I donīt know login what user writed, I can't lock his/her count.

Exist solution for this? Thanks
