This week's book giveaway is in the Other Languages forum. We're giving away four copies of Functional Reactive Programming and have Stephen Blackheath and Anthony Jones on-line! See this thread for details.
I am facing a problem I have found no solution to yet surfing the web.
Any help would be appreciated.
It's about JPA 1.0 persistence and how pKey generation is handled when class hierarchies and mappedsuperclasses are involved.
My Base Class is like:
However I found out that defining the @Id on the base class leads to all persistent subclasses sharing the same row in the tableGenerator and thus the same counter.
I would like to have separate tableGenerator rows (i.e. counters) for the generation of pKeys in each subclass
How can this behavior be achieved?
