RE: Examples of Pojo Free Code?

Avi,

Not sure if your question was to me, or to Mark.

If it was intended for me, then POJOs are wonderful, but you will in any case need to manage the interface to the database.
With an ORM this is part of the framework - but if you roll your own, you'll need to construct it.
Of course, YAGNI - but still...

Mark,

I am pretty much in agreement with you. (Struggling with a legacy Toplink app at the moment, Hibernate before that).
But, don't forget that an ORM framework is also providing you with other useful stuff around sessions, multi-user access, one-many/many-one/many-many mappings, error handling, transactions and so on.

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
