Don't waste your time with anything other than the ant built, all these
plugins and such will drive you mad tying to troubleshoot issues completely
unrelated to enhancement. I learned this the hard way because I was trying
to avoid using ant, it's an apache project so they expect you to use ant.

I have some queries that I have been using in my app for about a year now
but since I started using Beta 3 they fail validation because OpenJPA wants
me to include all of my select columns in the group by. Since most of the
select items are SUM(blah) I can't really do that and also there is no nee

Hi,
This is a problem that continues to haunt me intermittently since I first
started using OpenJPA and cannot understand why it comes up from time to

Hi Mike,
I had a similar issue when creating my reporting engine, since I always use
single table per class strategy I and a consistent foreign key name, I

org.apache.openja.Version.
