You are definitely missing some tables. No use in trying to login before the db schema is set up properly. I'd suggest to clean your database by deleting all tables first. Then follow Prabhats last advice to force Hibernate to use the Sybase dialect by changing this in all hibernate.cfg.xml files you find in jboss-portal.sar. Try to start up with this changes and review the log after that, looking for errors related to tables not being created.
