Hi Joerg,

Hi,
junit: Article - Produktgroup
Article holds an ID from Productgroup. In the  example it is the 
primaryKey from table Kategorien.


foreign keys from one table alway reference primary keys of another 
(or the same in case of self-join) table.

Can I use different field for it?


only by declaring it as primary key in the repository.

i get the message:

WARN: OJB broker could not materialize ....AbstractPersistent{1332}

The number shown is the fieldvalue i want to use for referencing the 
productgroup.
But the IndirectionHanler uses the primaryKey (which in my case can't 
fit)

hi thomas,
is the primary key in the repository allways primary key of the 
database-table?
or do they only have to be unique values?
