Hello Joerg,
in the turorial3.html file ( doc ).
see the section mapping inheritance hierarchy to the same table.
as far as I understand it's required additional column in the table
<field-descriptor
name="ojbConcreteClass"
column="CLASS_NAME"
jdbc-type="VARCHAR"
/>
or you have to derive a Class from
org.apache.ojb.broker.accesslayer.RowReaderDefaultImpl
and overwrite the method selectClassDescriptor to implement your specific type
selection
mechanism
hope to help you.
JL> hi,
JL> i want to map two classes to the same table.
JL> -PartentA
JL> -ChildA
JL> -ChildB
JL> ParentA is abstract. ChildA and ChildB must be retrieved by using
JL> the same atttributes (inherited from ParentA).
JL> I tried it, but by using the unique-key as
JL> >>>crit.addEqualTo("id", "515522");
JL> the wrong class is returned.
JL> is there anything special to do in the mapping?
