[eclipselink-users] ExpressionBuilder vs CriteriaBuilder...

[vaidya nathan <vaidyaatdst@xxxxxxxxx>]

JPA2 has CriteriaBuilder and i was expecting some examples of
eclipselink to have them but wherever i see I always see the
ExpressionBuilder which is eclipselink. Is there any relation between
these two. Also since Eclipselink is the reference implementation are
there any gaps in the JPA2 that Eclipselink specific apis are filling
in ?  It almost looks like CriteriaBuilder and Criteria are an exact
replica of ExpressionBuilder and Expression ..

We are currently using Eclipselink specific apis and want to know
whether we would be missing some functionality that is available in
Eclipselink if we migrate to using jpa 2 apis alone..

Cheers
