Hi

I have an Entity that has a generated Id - a surrogate key that has no business meaning. Entity also has a business key (bk). This Entity is persisted initially in a Hibernate managed repository.

In a different system, an equivalent Entity (having the same bk) is updated. This updated Entity needs to merged back to the Hibernate repository.

Is there a way I can tell Hibernate to check and update based on another key, other than the primary key ?

Regards,
Shunya
