service layers

[ali.aljadiri]

Hi there,

I am new to Spring, so excuse the coming primitive questions, whereas I am utmost grateful for any help!

I am using Spring along with NetBeans. My supervisor has already done some prior work. Under one of the packages of the project we are working on now, the following files/subpackages exist:
xxx.recommender.impl
xxx.recommender.interfaces
xxx.recommender.model

I have code files under a different project which I need to copy over to this one. What do the above mentioned subpackages represent and how do I know which code files get copied where to with which modifications?

Thanks a lot in advance for your help!
Ali

Put all your domain objects (Pojo mapped with Database) in xxx.recommender.model


put all your service classes(business logic) in xxx.recommender.impl

put all your service interfaces (who implements service classes) in xxx.recommender.interfaces

This seems to be a right advice, but even better one is: "Ask your supervisor about his/her intentions".

put all your service interfaces (who implements service classes) in xxx.recommender.interfaces
