Subject Re: support for identifying relations in JPA/OpenJPA
Date Wed, 30 Jul 2008 23:34:18 GMT

Hi,

> relations) between two entities?

Yes. OpenJPA supports relation as identity. JPA 2.0 will standardize on this
feature as 'derived identity'. This feature is described and demonstrated in
OpenJPA manual [1]. A JIRA issue where multi-level derived identity is being
used can be found here [2].
