Hi Gianfranco,
can you please double check the password stored in the database for that
user is NOT NULL? The line throwing the NullPointerException already
checks for null values on all parameters but on password retrieved from
database.
To be completely sure please grab the query hibernate issue to retrieve
the user's datas and double check the returned values.
Originally the database script was using a NOT NULL constraint on the
password column.....have you changed that constraint?
Please let us know how things evolve
