Examples of Pojo Free Code?

I'm running an Agile Development course with some wonderful people at a
client who're addicted to their existing ORM. We've been discussing the
evil involved in Data Classes (i.e. classes with no behaviour). In their
world the habit of creating data classes comes from the fact that their ORM
(Hibernate and JPA) creates POJO type objects and they manipulate them.
They get the problem but would live to see an example of project that
doesn't do this.

Do you know an OpenSource project that doesn't a use POJOs to get its data
in/out of an RDBMS? Do you know an ORM that helps people avoid creating
Data Classes?

BTW I'm asking on this list lacking a better place.

Cheers
Mark
