Hi,
I am attaching below an section from xyz.hbm.xml document

<set name="subGroups"
cascade="all-delete-orphan"
inverse="true"
lazy="true"
batch-size="5"
sort="natural">
<key column="groupnode_id"></key>

<one-to-many class="com.bosch.mds.types.hierarchy.SubGroupNode"/>

</set>

I need to know, how can programatically retrieve the class represented by the <one-to-many> tag for the attribute value <set name="subGroup"> from the above section. I have got the PersistentClass from the Hibernate Configuration.

Please help !!

Code:

String collectionRole = persistentClass.getEntityName();
Collection subGroupMapping = configuration.getCollectionMapping( collectionRole );
OneToMany subGroupElements = ( OneToMany ) subGroupMapping.getElement();
String associatedEntity = subGroupElements.getReferencedEntityName();
// or :
// PersistentClass oneToManyRef = subGroupElements.getAssociatedClass();
// String associatedEntity = oneToManyRef.getEntityName();
// Class associatedClass = oneToManyRef.getMappedClass();

Beware, though, that you need to make sure the associations are fully resolved *before* making these calls.

Steve,

One remark regarding your code, shoud be

String collectionRole = persistentClass.getEntityName() + "." + attribute;

Anyway my problem was this one http://forum.hibernate.org/viewtopic.ph ... highlight= (please see the topic and my post).

Can you please have a quick look on it ?

P.S. How can I rate your answer ? (or only the thread starter can ?)

Thanks 4 your time.
