What kind of more complucated, and what kind of custom logic? I haven't
used Hibernate/JPA, but want to start, so i'm interested in this sort of
stuff.

A colleague said something similar, FWIW - great for simple cases, but
struggling on more complex stuff. His example involved manipulate a
many-many relationship on a set of detached objects - when he reattached
them, Hibernate went mad.

My experience is that:
- if you start with Hibernate and create the database for
Hibernate, then it works great
- if the database is an existing database created for
other usage, then using Hibernate to access it can
become very painful
