Hi,
I try to map two classes Address and PersonAddress (a subclass of Address)
using the joined table per sublcass strategy. This is my mapping:
<class-descriptor class="de.armax.sandbox.entity.Address"
table="Address">
<field-descriptor autoincrement="true" primarykey="true"
column="adrOID" jdbc-type="VARCHAR" name="oID"/>
<field-descriptor column="adrAttribute" jdbc-type="VARCHAR"
name="attribute"/>
...
</class-descriptor>
<class-descriptor class="de.armax.sandbox.entity.PersonAddress"
table="PersonAddress">
<field-descriptor autoincrement="true" primarykey="true"
column="padOID" jdbc-type="VARCHAR" name="oID"/>
<field-descriptor column="padAdditionalAttribute" jdbc-type="VARCHAR"
name="additionalAttribute"/>
...
<reference-descriptor
auto-delete="true"
auto-update="true"
name="super"
class-ref="de.armax.sandbox.entity.Address">
<foreignkey field-ref="oID"/>
</reference-descriptor>
</class-descriptor>
Storing new Addresses or Personaddresses works fine. But when I reload
Adresses using
broker.getIteratorByQuery(QueryFactory.newQuery(Address.class, new
Criteria()));
OJB seems not to care about what type these addresses have. All returned
entities will be of type Address, even if they were stored as PersonAddress.
Is this a bug or am I missing something here?
Thanks for any help,
Peter
P.S.: I'm very sorry if this mail appears two times on the list. I send it
from a bad account before and I'm not sure weather the ojb user list accepts
this.
