Sorry.
I've forgot to publish the field-descriptor for the salesPersonId:
this is the right version:
2003-10-28 11:10:45,307 ERROR [STDERR]
org.apache.ojb.broker.OJBRuntimeException: Incorrect field reference

I defined the following interfaces and classes:
public interface Price implements Serializable {
public String getId();
public Article getArticle();
public SalesPerson getSalesPerson();
public double getValue();
}
public class CustomerPriceImpl implements Price {
private String id;
private String articleId;
private String salesPersonId;
private double value;
private SalesPerson salesPerson;// 1:1 reference to Customer
public Customer getSalesPerson() {
return (Customer) salesPerson;
}
}
public interface Article implements Serializable {
public String getId();
public String getArticleNo();
public Collection getPrices();
}
public interface SalesPerson implements Serializable {
public String getId();
public String getName();
public Collection getPrices();
}
public class CustomerImpl implements SalesPerson {
private String id;
private String name;
private Collection prices = new ArrayList(); // 1:n prices
}
the mapping look like:
!-- mapping interface Price --
class-descriptor class=domain.Price
extent-class class-ref=domain.CustomerPriceImpl/
/class-descriptor
class-descriptor class=CustomerPriceImpl
field-descriptor
name=id

you might better use domain.CustomerPriceImpl here
proxy=true
auto-retrieve=true
auto-update=true
inverse-foreignkey field-ref=salesPersonId/
^^^
now OJB expects domain.Price to have a field-descriptor
named salesPersonId.
/collection-descriptor
/class-descriptor
I think you have two ways to fix it:
1. make the type of the reference domain.CustomerPriceImpl, or
2. add a field-descriptor for salesPersonId to the
class-descriptor of domain.Price (I know it is an interface,
but that's o.k.)
