For us it's Hibernate 3 still. We'll be moving to JPA in the code (with
Hibernate as the underlying implementation) soon.
with Struts 2. Are you
using custom interceptors?
Er, why?
Or, more specifically, yah we have some customer interceptors, they
don't have anything to do with our persistence layer, though.
We are using Spring's OSIV filter if that's of interest to you.
, type converters?
Nothing related to persistence.
Spring?
Absolutely, and heavily. Spring for DI, DAO layer, service layer,
integration testing, Spring AOP for the fault barrier (advice on the
execute method of the Actions) and various Spring "utilities" like the
scheduling integration.
model-driven?
I don't find the "formal" model driven stuff in S2 to be of much benefit
("formal" meaning the interceptor combined with a getModel method
implementation in the Actions).
But we do a lot of direct-injection into model objects from the view
layer simply using OGNL expressions for our field names and ensuring the
model-object is a property of the action with getters/setters. Most of
the model objects we inject into (from forms in the view) are persisted.
We do find that doing the params/prepare/params interceptor sandwich is
a fairly elegant way to hydrate from a form-provided ID and then let
other fields inject into that newly hyrdated object on the second params
pass.
the scope plugin?
Not quite yet. But very soon.
I've been seriously playing with WebFlow and will probably use *some*
sort of framework-provided scoping very soon (WebFlow or the scope
plug-in). I'm soooo tired of managing conversation scopes by hand.

Hopefully that's the sort of stuff you're interested in hearing about.
