hi!
you probably call your beans method which was designed and implemented for
that purpose.
sth. like this:
User user = new User();
user.setUserName(loginid);
if (theUserValidatorBean.validate(user))
dosth...
else
dosthelse
in UserValidatorBean you eighter have a list (or a map, or...) to find out
whether the user with the given userid exists on your system, or you connect
to a database to check that, or you parse a file, or your Bean has
functionality implemented which makes it possible for it to call you via
telephone and ask whether this user should be allowed to log in or not...
btw, you can find out if the username is null and more then "" with
(userid!=null && !"".equals(userid)).
