Hi,

I'm trying to map an EMF model to a legacy database that I cannot
change. I'm creating the orm.xml programmatically using a
http://www.elver.org/xsd/teneo/persistence-mapping-hibernate .xsd file as
input (besides the ecore). I would like to use optimistic locking with
the eclipse link AllFieldsLockingPolicy because the normal optimistic
locking with a version field does not work in my case as there is
another application working on the same database.

I didn't find a place to add the AllFieldsLockingPolicy setting. I tried in:
* persistence.xml: this would be great; just setting a default for
everything, but I think it's not possible
* PersistenceOptions: There is an optimistic locking property, but
it's just a boolean
* The persistence xml file based on
http://www.elver.org/xsd/teneo/persistence-mapping-hibernate .xsd: Not
surprising there is no EclipseLink setting in there.

Thanks for help,
Peter


PS: Is there also an EclipseLink specific persistence-mapping schema?

Hi Peter,
Unfortunately Teneo supports jpa 1.0, the same for the orm.xsd in Teneo. For recent and specific EclipseLink support you
have to look at Texo I am afraid. The Texo orm supports the optimistic locking policy you are looking for. But Texo is
more a server side solution. Although it is easy to convert Texo objects to EMF objects, so it would be quite possible
to read objects from the database using eclipselink and convert them to EMF objects on the fly:
