I have just found this page: http://incubator.apache.org/graffito/jcr-mapping/index.html It seems that they have-solved/are-solving this issue in the same way as ORM frameworks. Interesting if it really works.

I don't know if I have the best design, but I use separate persistance mechanisms for my objects. For JCR objects, I use one spring service, for my hibernate objects, I use another spring service. My hibernate objects maintain a string property of the path to the Node (e.g. the product image) ----- Original Message ----- From: "Ali Sakebi" <[EMAIL PROTECTED]> To: [email protected] Sent: Thursday, May 24, 2007 2:45:21 PM (GMT-0500) America/New_York Subject: Re: JCR and Domain Model or Business Logic? So u use jcr object as data object, and wrap them or textual reference to them with business logic objects? How do u manage lifecycle (loading, CRUD) of ur objects graph/tree? Is ur jcr persistence transparent to ur domain model? What about other patterns, is it common to implement business logic using transactional script pattern and use jcr objects as data objects?
