Does someone know a simple example application GAE with
Hibernate and Cloud SQL?
Supposedly Cloud SQL support.
(Forming:hibernate.cfg.xml, working with MySQL locally or Cloud SQL
in
Server)
The link:
https://developers.google.com/cloud-sql/
It does not mention anything with regard to Hibernate.
Hibernate is not supported by GAE. This is
documented on the GAE Java Whitelist.
Furthermore, JPA and JDO are supported so this should provide all the
ORM you need.

Hi Cosmin!
I have decided to use JPA due to the fact that with JDO I met several
bugs associated
with GAE and JPA I had fewer problems, beyond the restrictions that
there imposes GAE of the correct
use of the oriented object programming . Because of it I recommend to
you to use for GAE, JPA...

Hi! I have a problem with the persistence of an existing object

sometimes persist and sometimes not persist in the

If so, then you should re-attach it prior to updating
