Hi,
I've startet to see if I can migrate some of my projects from using
eclipselink 2.5.1 to openjpa 2.4xx.

Does anyone know if there are any resources anywhere which discribes this?.

I've just switched provider to openjpa and it seems that openjpa fetches
differently from eclipselink.

example:

1. use deltaspike repository with jta support

2. Stateless ejb handling request from cdi beans (View access scope)

3. onetomany are lazy fetched and unidirectional

in my @VASB i fecth all customers via ejb call
if I try getchildcollection for one of my parents in @VASB, it returns null.

Switching back to eclipselink, get child collection returns collection. (and
i off cource see the sql logs)

I'm quite new to openjpa, but I would expect the two would operate similar
without any changes...but obviously not.

This is tomee 1.7.0-snapshot.

My idea was actually to get openjpa works the same way my eclipselink
implementation was, and the add LRS features and more.

If this is not tomee dependent, I'll move over to stackoverflow :-)

br hw
