Customers, partners and system integrators often develop extensions to
Oracle E-Business Suite (EBS) applications. Such extensions have
traditionally used the same technology stack (Forms or OA Framework)
that the original EBS application was built with.  This ensured that
the extensions are fully compatible with the rest of the installed EBS
applications.

Our E-Business Suite Applications Technology group has released a
long-awaited whitepaper addressing this question. This whitepaper
discusses the similarities, differences and overlaps between the OAF
and ADF stacks. 


If you’re considering these technology stacks for your Apps R12 extensions, I’d strongly recommend reviewing this whitepaper:
