I thought the solution would be to set the class on the component to be an
implementation of the interface. However looking at the source code for the
hibernate xdoclet module it doesn't bother to look at the class and just
checks the class that the method returns.
.... here's a copy of a fragment of the code causing offence:
/**
* Gets the unique identifier of this predicate
*
* @return Unique ID of this predicate
* @hibernate.id
* @hibernate.component
class="com.yyyyyyy.ebasket.util.GUIDImplementation" prefix="predicate_guid"
*/
public GUID getPredicateIdentifier() {
return this.predicateIdentifier;
}
.... and heres the corresponding fragment of the hand crafted hibernate
mapping file that works.
<composite-id name="predicateIdentifier"
class="com.lastminute.ebasket.util.GUIDImplementation">
<key-property name="id" column="predicate_guid">
</key-property>
</composite-id>
What's the solution? Do you think this is a bug?

Subject: [Xdoclet-user] xdoclet/hibernate problems with components and
composite-id
I've got a problem with components and composite-ids with hibernate and
xdoclet.
I'm retrofiting hibernate onto an existing database and application, and I
have
several entitites with have a primary key of GUID, where GUID is an
interface.
If I try to use the GUID as an id then xdoclet/hibernate complains that is
not
serializable or does not implement equals(Object) - when in fact it does.
Is this a common problem? Any work arounds?
Kevin
