Hi,
I'm facing a nasty issue with my freshly refactored entity class hierarchy
(things did work before):
openjpa.MetaData - The class "com.mycompany.FamilyAggregationEntity" listed in
the openjpa.MetaDataFactory configuration property could not be loaded by
org.apache.openejb.arquillian.openejb.SWClassLoader@5b408dc3; ignoring.
2091 corbox_appgateway TRACE [main] openjpa.MetaData -

The entity class in question does appear in the list printed by OpenJPA as
'persistend type name' before the exception happens:
2043 corbox_appgateway TRACE [main] openjpa.MetaData -
parsePersistentTypeNames() found [... com.mycompany.FamilyAggregationEntity ...]
I have a hierarchy of entity classes, like this:
@Entity
@Inheritance(strategy = InheritanceType.TABLE_PER_CLASS)
public abstract class AggregationEntity implements Aggregation, Serializable {
..
}
@Entity
@Table(name="...")
@NamedQueries({
...
})
public class FamilyAggregationEntity extends AggregationEntity {
..
}
There are other entity subclasses of AggregationEntity, and these were present
and working before adding FamilyAggregationEntity..
I also tried @MappedSuperclass on AggregationEntity instead of
@Entity/@Inheritance (which is probably better JPA-standards-wise), but that
didn't help either...
Any ideas greatly appreciated.
Thanks,
Uwe
