Hi,

I found in "Hibernate in Action" the following example (page 333):
<composite-id>
<key-property name="username" column="USERNAME"/>
<key-property name="organizationId" column="ORGANIZATION_ID"/>
</composite-id>

The problem is that I can't find a way to fetch this composite-id in java.
ClassMetadata.getIdentifierPropertyName() returns null and ClassMetadata.getIdentifier() returns the all class.

Is there any other way?

Thanks
Alex

replace your composite-id element with the below information



Then you can get identifier information from SessionFactory.

Ok,
But the question if I can get the ClassMetadata.getIdentifier() without the
class="MyCompositePK"

Thanks,
Alex

If you use integrated composite key then you need to populate each field that makes up the key, in the domain object, to do an operation that requires the key, eg, load and get. There is no Java key to return as its just properties on the domain object.
