Hi Robert,
could you please post the mapping and java source for class Country (I
expect that this is the class which declares field 'publicationDates'?) too.
regards,
Armin

Hi,
Can anyone tell me why I get this runtime exception when using OJB as
the inner class is neither abstract nor an interface and has a no
parameter default constructor. The inner class does extend an abstract
class, but that doesn't seem to be a problem.
Thanks,
Robert Giddings
