Business Objects

[mgorav]

Hi All,
Where should the business logic reside. We have been thinking of using BO which wraps the JPA entity and put our business logic into it. BO will be used a prototype bean + a provider (per BO Object) which convert JPA entity into BO + a service per BO.

I think using this approach we are adding lots of layering. Also the BO are not meant to be used by the UI component (in our architecture)

Does the above approach solves the martin fowler suggestion
"At its worst business logic can be very complex. Rules and logic describe many different cases and slants of behavior, and it’s this complexity that objects were designed to work with. A Domain Model creates a web of interconnected objects, where each object represents some meaningful individual, whether as large as a corporation or as small as a single line on an order form." - Martin Fowler

or it making our domain model - anemic

Please suggest some alternative ways???

Thanks,
Gaurav Malhotra
