Is it OK to use JDO now.
Hi.
In the OJB site it said
"We currently provide a plugin to the JDO Reference
Implementation ... A full JDO implementation is
scheduled for OJB 2.0"
I wondered, what is the different between JDO
Reference Implementation ant JDO implementation. Is
it ok if I use JDO Reference Implementation in my
application right now. Do I need to change my code in
the future if OJB 2.0 is completed. Please enlighten
me.
Cheers.

I came from a JUG (CTJUG) meeting where JDO was the topic of the day.
We had Robin Roos as a guest speaker. (author of Java Data Objects book
(isbn: 0-321-12380-8) http://ogilviepartners.com/)
He himself indicated that the JDO RI is meant to be merely a working
implementation of a current specification.
So how reliable it is *for production environment* is a very good questions.
I myself wouldn't rely on reference implementation for production. ;)
Anyway from what I gather from meeting we had today, future of JDO 2.0 spec.
looks very promising! (Aggregation, standardised relational mapping, etc.)

Hi:
Short answer: Yes, you can use it.
Long answer:
I think the statement below must be rewrote, because I had the same
question as you some days ago. :)
OJB already work with JDO. You can use it. Currently, the OJB support for
JDO is full working. OJB currenlty use the Sun JDO implementation. But we
cannot bundle Sun JDO implementation with OJB for License problems. You
need to download it from the Sun website.
This is one of the reasons why one of the OJB community's targets for OJB
version 2.0 is to release his own JDO Implementation.
I think as JDO is a standard, then OJB JDO implementation will be
compatible. Please also beaware that currenlty is a discussion of the JDO
2.0. If the OJB community prefer to target JDO 2.0 instead of JDO 1.0
maybe there can be some problems. I dont know if there is a compatibility
requirement.
Best Regards,
Antonio Gallardo

The JDORI is not licensed, by Sun, for commercial use. Other than that
it works fine. It isn't tested as thoroughly as the PB and ODMG api's,
so there may be things hiding.
