[AUTH] problem with security.xml and login

Hi all,

I am a new user of this framework and I have some problems with the users authentication. First of all, I'm using smartweb auth v. 0.8.1, and I have modified the name of smartweb.jar.xml in security.xml, under suggestion of a developer, but after this change I am not able to do a correct login. If I use the name of "smartweb.jar.xml" I can login, but the roles defined in the configuration file are not met. Can anyone helps me? Thanks a lot in advance...

Below the stack-trace of the error:
type Exception report

message

description The server encountered an internal error () that prevented it from fulfilling this request.
