Nested services

[titiwangsa]

i think i read somewhere, most probably from one of the previous posts,
that using nested DAOs are bad.
but what about nested services?

that using nested DAOs are bad.
but what about nested services?

yes i am agree about fo DAO area,

i think that the answer is nested BO

each entity should has a DAO object and this a BO, some requerimentes make you to create a special BO that call or use 2..N BO (nested services)

BO?
Bussniess Object?
i have entities (tables), each entity has a dao,
a services uses multiple dao.
the @Transactional attribute is in the services

BO = services?

i have some logic that exists in more than one service.
using a nested service looks like the easiest way..

Services have to collaborate with other services otherwise you are going to have to copy and paste code. Where else would the common code live?

[titiwangsa]

simply put,
nested dao = bad.
nested services = common practice?
ok. thank you for clearing that up.

[karldmoore]

nested dao = bad.

Yeah this doesn't sit quite right with me, sounds like some refactoring might be in order.

nested services = common practice?

Hopefully, otherwise I'm doing it all wrong .
