Yes, that will make your classes available to Catalina's internal class
loader.

You would need to sublcass whichever authenticator class you are using
(such as
org.apache.catalina.authenticator.FormAuthenticator) and override the
authenticate()
method, something like this:
public boolean authenticate(HttpRequest request,
HttpResponse response, LoginConfig config) {
if (!super.authenticate(request, response, config))
return (false);
MyPrincipal principal =
(MyPrincipal) request.getUserPrincipal();
if (principal == null) {
// We are asking for the form login page
return (true);
} else {
// Copy the stuff we need into the session
HttpSession session =
((HttpServletRequest) request.getRequest).getSession();
session.setAttribute("userStatus", principal.getStatus());
...
return (true);
}
}
Note that the attributes you save need to be JDK classes like String,
because the
user classes you store in the server directory are not visible to web
apps.
