Hi,
say I have one instance to delete, an instance of B knowing that A
contains one to many B.
Should I merge A with one less B, that should delete the required B or
should I explicitly delete that B with a delete by query or should I
use the remove(thatB) API ?
What are the differences
did you had a look on that method on the EntityManager :
setMultithreaded(boolean multi)
Whether the entity manager or its managed instances are
used in a multithreaded environment.
It sound like EntityManager has to know wheter or not it is used with
threads.
Probably the
+1
Java 5 for 1.0.x and 1.3.x
Java 6 for 2.x
I think this could better for OpenJPA adoption.
Concerning my own usage, I'm no more using Java 5 ... so I would be
pleased with everything Java 6.

I already read that blog post and that's after reading it that I
decided to try OpenJPA.
I spent a lot of time as a consultant, in previous life, to educate
people to that concept in the early 2002-2003.
It was with OJB (as far as I remember) and I didn't know how to name
that thing.

The need is simple : get trees of partially valuated business object
instances from the big graph of possible linked business classes.
The fact came from old SQooL (a bad IT joke from old school and old

1. only get back from DB what you need.
2. the other thing is to try to make as few
Any comments on that vision ?

Hi,
My question is is there simpler things to do ?
Please, review that idea and don't hesitate to comment ...
Step 1 : I want partial object, not hashtables. It could be a Person

Hi,
Suddenly, I'm wondering if OpenJPA version 1.2.1 is the lattest stable
version or the dev version that will implement JPA 2.0 ?
In other words, witch one is the stable production ready version :
1.2.1 or 1.1.0 ?
Sorry, I got the confirmation on the site : 1.2.1 is the lattest
stable version witch I'm trying to use.
Version 1.3.0 is the dev version that will correct bugd and version
2.0 is in millestone 8 for JPA 2.
