Hi,
I've done a certain amount of work on this topic with a couple of
others, but haven't gotten anywhere final. I've got the beginnings of
a query builder API + implementation that generates JPQL strings,
which should be usable with any JPA implementation.
I'm working with the others who have been involved to figure out where
to put the source for this; ideally, I'd like to put it somewhere
other than in org.apache.openjpa, since it just generates JPQL, so can
be used with any JPA provider.
