Hi,
Thanks. Got that problem solved. It works fine when i map a compound primary
key from one table to another with a single primary key. However when i map
compound primary keys to compound primary keys, i get a NullPointerException
which results from [org.apache.ojb.broker.accesslayer.IndirectionHandler]
ERROR: Met.....
e.g Table A:
<class-descriptor
class = "com.data.A"
proxy="dynamic"
table = "Shipment">
<field-descriptor id = "1"
name = "shipmentOid"
column = "SHIPMENT_OID"
jdbc-type ="INTEGER"
primarykey = "true"
/>
<field-descriptor id = "2"
name = "countryCode"
column = "REF_COUNTRY_CD"
jdbc-type ="VARCHAR"
primarykey = "true"
/>
....
<reference-descriptor
name="piece"
class-ref="com.data.B"
proxy="true">
<foreignkey field-id-ref="1"/>
<foreignkey field-id-ref="2"/>
</reference-descriptor>
</class-descriptor>
Table B:
<class-descriptor
class = "com.data.B"
proxy="dynamic"
table = "Piece">
<field-descriptor id = "1"
name = "shipmentOidPiece"
column = "SHIPMENT_OID"
jdbc-type ="INTEGER"
primarykey = "true"
/>
<field-descriptor id = "2"
name = "typeFlg"
column = "TYPE_FLG"
jdbc-type ="VARCHAR"
primarykey = "true"
/>
<reference-descriptor
name="piece"
class-ref="com.data.A"
proxy="true">
<foreignkey field-id-ref="1"/>
<foreignkey field-id-ref="2"/>
</reference-descriptor>
</class-descriptor>
