I would suggest that we start right away with a RDBDAS-based solution.
I also think that the best place to start would be with an interface
that is weakly typed. That is, a service interface in terms of
dynamic SDO's. If we go this route we can avoid the generation (by hand
or otherwise) of

H...a service modeled as a property is what seems odd.
I'm trying to keep an open mind.
Imagine drawing a picture of this using the icons from the
SCA spec. You'd have some kind of a connection from a
component's property to a database? That's what
checked in.

I think implementation.jpa is about simplifying the configuration

Great. I would like to help with this. I have been thinking for awhile
about how to best integrate the RDB DAS within SCA. For example, the
current BBank scenario uses the RDB DAS as a utility but it would be
nice if it could wire in a RDB DAS service or be injected with a
configured DAS.
Do you mean the Hibernate session API without using the entity manager?

Hi,
I checked in a skeleton of EJB3 persistence support (using OpenJPA)
that will leverage the system service work I just did. If anyone is

I am interested in adding the Hibernate support. However, could you pls
elaborate on the use cases for persistence in Tuscany?
