we use hibernate extensively in our online content management system.  the
only jdbc in the whole application is for streaming blobs.

there is already a somewhat similar project there:
http://jakarta.apache.org/ojb/.  while they are similar in the sense that
they are object/relational mappers, they have differenct features and
architectures.  i have never used OBJ so i can't speak for it, but i have
been very happy with hibernate's functionality, simplicity (read: ease of
use) and robustness.

O/R mapping and CMP are quite different.  off the top of my head, i prefer
O/R mapping because:
1. it lends itself to more agile development
2. is is better suited to applications that model their problem domain in a
very OO manner

hibernate works well in stateless session beans within jboss (and probably
any other j2ee app server) with container managed transactions.
