Hi,

is it possible to map following tables:

Table1
PK1 --Primary key (PK)
PKFK1 -- Primary and foreign key
PKFK2

Table2
PK1
PK2

PKFK1 and PKFK2 is foreign-key and primary-key in table1 and primary-key in table2
Is it possible to map this tables in hibernate?
<composite-id
name="id"
class="Table1PK">
<key-property name="PK" column="PK1" type="type" />
<key-many-to-one name="PKFK1" class="Table2Bean" />
<key-many-to-one name="PKFK2" class="Table2Bean "/>
</composite-id>

My tries could not map the table1.

Thanks for help.

Try this :

Code:

<composite-id name="id" class="Table1PK">
    <key-property name="PK" column="PK1" type="type" />
    <key-many-to-one name="theBean" class="Table2Bean" />
        <column name="PKFK1" />
        <column name="PKFK2"/>
    </key-many-to-one>
</composite-id>
