You have to tell OJB to use a PersistenField implementation supporting this in OJB.properties first, as it is not yet implemented in the default implementation:
PersistentFieldClass=org.apache.ojb.broker.metadata.fieldaccess.PersistentNestedFieldMaxPerformanceImpl
if your class has an attribute "address" of type Adress, the mapping for the "street" attribute of "address" would look like follows:
<field-descriptor
name="adress->street"
column="ADR_STREET"
jdbc-type="VARCHAR"
/>cheers, Thomas

Could anyone tell me how to implement the Single Table Aggregation pattern for a 1:1 relation using OJB? RowReaders seem to solve the problem for reading, but I'm stumped as to how to write to such a table.
The pattern is found here:

Any help is *greatly* appreciated.
