Hallo,

I've got the following object model

interface SellableItem;
=>Set orderLines

class Product implements SellableItem;
class ServiceContract implements SellableItem;

class OrderLine;
=>SellableItem item;

The relationship between SellableItem and OrderLine should be a bidirectional 1:n relationship.

I've tried to map this but I always get an error using the ExportTool:
Error: net.sf.hibernate.MappingException: Association references unmapped class: demo.myshop.model.hibernate.SellableItem

I hope someone can help me with this mapping.

Thanks,

Stephan

You need to map concrete classes (which may have interfaces) since they must be instanciated. In your case you will also want to look into polymorphic mapping strategies. See documentation at http://www.hibernate.org/hib_docs/reference/html/or-mapping.html#or-mapping-s1-11

Thanks for your quick answer.

I hope I understand you right, you say I have to do it via inheritence ?

Thanks,
Stephan
