Hi,
isn't it possible to declare one field (or a combination of fields) as PK (in OJB metatadata, not in DB) to allow OJB the creation of unique Idenity objects?
OJB PK fields are independent from the DB PK's.
The creation of Identity objects of the persistent objects is needed to use caching and references (and other internal services).
regards, Armin

Have you tried it? I am pretty sure it works; I think I've done it before, but if it doesn't work then I'd be interested to know.

Is there a way to have a class with no primary key field descirptor? All I want to do with OJB is retrieval.
