Communication between Data-, Business-, and Presentation-Layer

[Former Member]

Hi everybody,

which technology should be used for a Business Layer? EJB?

we have a Presentation Layer (Web Dynpro 7.2) and a Data Layer (EJB 3.0) but we don't know which technology we had to use fo our Business Layer. I think the best way is to use EJB's for the Business Layer in order to import them into Web Dynpro.

Presentation Layer (Web Dynpro 7.2)

Business Layer (EJB 3.0)

Data Layer (EJB 3.0)

What ist the best way? And what about Hibernate or JPA, is it possible to use this technologies?

regards,

Sid

Hi,

You can create a CAF project for interaction with the Business Layer (EJB) from the Presentation layer. You can also use JPA with EJB for DB transactions.
