James, Eduardo, Jeremy, thank you very much for your input!
I follow your discussions with great interest.
Can you recommend a book on this sort of questions? I have read books
on Spring and Hibernate but not from this high-level point of view.
Cheers,
Kaspar

Ok I got it. One question, consider that you have this model:
Person 1xN Address
You have a screen that list a detailed view of a person, including a
list of addresses. What approach do you use to implement it?
- A service method that returns a Person entity with eager load of the
list of Addresses? (if you don't need always the addresses this
doesn't make sense)
- A service method that returns a Person entity with lazy load of the
list of Addresses? (it could be a problem in a JEE environment)
- Two service methods, one to return the Person entity and another one
to return the of addresses?
Thanks,
Eduardo S. Nunes

Yes, I understand you too. What do you do when you have to send a
set
of entities and a calculation for each entity? you encapsulate it
inside another class?
A domain-driven design advocate would say that the entity knows
how to
calculate what you need and you can ask it for the calculated value.
