Problem:
In fairly complex application I tried to mixing table per subclass and table per class hierarchy inheritance. Schema:product //base entity ---tour //table per class hierarchy with products ---- cruise //single table hierarchy to tour the code: component display="product" persistent="true"{ property name="item_id" type="uuid" ormtype="string" fieldtype="id" generator="uuid" hint="key of the product"; } component display="tour" extends="product" persistent="true" joincolumn="item_id" discriminatorcolumn="tourtype"{ } component display="cruise" extends="tour" table="tour" discriminatorValue="cruise" persistent="true"{ property name="vessel" type="string"; } This Schme won't create with the error . "No discriminator found for cruise. Discriminator is needed when 'single-table-per-hierarchy' is used and a class has subclasses". Obviously, there is a discriminatorValue="cruise" in component cruise.Mixing inheritance strategies should be possible accroding to the hibernate documentation.http://docs.jboss.org/hibernate/core/3.3/reference/en/html/inheritance.html#inheritance-mixing-tableperclass-tablepersubclass
Method:
component display="product" persistent="true"{ property name="item_id" type="uuid" ormtype="string" fieldtype="id" generator="uuid" hint="key of the product"; } component display="tour" extends="product" persistent="true" joincolumn="item_id" discriminatorcolumn="tourtype"{ } component display="cruise" extends="tour" table="tour" discriminatorValue="cruise" persistent="true"{ property name="vessel" type="string"; }
Result:
No discriminator found for {enity]. Discriminator is needed when 'single-table-per-hierarchy' is used and a class has subclasses
