I tried a simple ROO Spring MVC/JPA project (that generates persistence.xml) and it does not include the list of classes in the persistence.xml either. And that code works for both Oracle and MSSQL. It is a Spring MVC servlet, however.
Hmmm.... Could console mode vs. web apps have have anything to do with it?
On the one hand I don't think it should.
On the other hand, something in spring is probably doing it. Something that I'm calling in my servlet that I'm not doing in my console mode application. Hmmm... Both apps are pretty simple.
I wonder if I can cajole ROO into making a console mode application?
