Hi all,
I've used hibernate for a while, and I'm having a bit of trouble
switching to JDO. I have several entities that all entities will
share. Rather than a parent table, I'd prefer these columns be
embedded directly in each entity. As such, I've defined my abstract
entity and child entity in the classes below. However, whenever I try
to run my unit tests or the jetty environment, I always receive the
following error.
org.datanucleus.exceptions.NoPersistenceInformationException: The
class "com.onwebconsulting.inventory.model.Part" is required to be
persistable yet no Meta-Data/Annotations can be found for this class.
Please check that the Meta-Data/annotations is defined in a valid file
location.]]
According to my Eclipse console I have 1 class that has been
Enhanced. Any ideas what I'm doing wrong?
DataNucleus Enhancer completed with success for 1 classes. Timings :
