Hi all,

We're in the process of evaluating whether to use EclipseLink as our JPA
provider for a green field project. We have lots of experience with
Hibernate so we're trying to see if the proprietary extensions offered by
Hibernate are matched by EclipseLink. So far, here's what we've gathered:

caching: yes
collection of elements: yes
criteria API: yes
indexed lists: NO
delete orphan cascade: NO

We couldn't find any corresponding feature in EclipseLink with regards to
indexed lists (Hibernate's @IndexColumn) and delete orphan cascade
(Hibernate's @Cascade(CascadeType.DELETE_ORPHAN)). The last extension
has been extremely important to us in the past and its absence from
EclipseLink could be a deal breaker.

Does anybody know if EclipseLink offers these two extensions, or something
similar?

Thanks,
GB

I have just found that EclipseLink offers "private-owned" collections that
seem to match the concept of orphan removal available in Hibernate. Good
stuff!

From http://wiki.eclipse.org/EclipseLink/Development/JPA_2.0/orde red_lists
I gather that there is nothing similar to @IndexColumn in EclipseLink, but
there will be in the JPA 2.0 version. Oh well, we can live without this
one.

Thanks all,
GB
