Hibernate is not directly concerned about Access, the first thing is to provide a jdbc driver for access. If you don't have this, you can't go further (or maybe by using jdbc-odbc bridge).
Then, you should try and precise the dialect :
http://www.hibernate.org/hib_docs/refer ... l-dialects
But it seems that Access has not one...
To sum up, try to open a jdbc connection manually without even using Hibernate, then only try to use Hibernate. Hibernate uses JDBC, so if you aren't able to access the db with jdbc, forget Hibernate :-).
