EnterpriseTest.java:
public void testEnterprise() throws HibernateException {
Session session = factory.openSession();
List list = session.createCriteria( Enterprise.class )
.add( Expression.like( "corpName" , "%电子%" ) )
.add( Expression.eq( "entityTypeID" , "1100" ) .setMaxResults( 10 )
.list();

System.out.println( "Result counts : " + list.size() );
for ( int i = 0 ; i < list.size() ; i ++ ) {
Enterprise enterprise = ( Enterprise ) list.get( i );
System.out.println( "Enterprise is : " + enterprise.toString() );
if ( enterprise instanceof Company ) {
System.out.println( enterprise.toString() );
}
}
session.close();
}

I have traced into the EntityPersister, there are two items in subclassesByDiscriminatorValue as the following:
key="gov.gdgs.enterprise.Enterprise" value=gov.gdgs.enterprise.Enterprise
key="1100" value=gov.gdgs.enterprise.Company

Why could not get the subclass's class?

Thanks a lot.

Sorry.

FT, the reason is in the DB, the discriminator column is char(6) with real data has only 4 chars!

After mofied <subclass name="Company" discriminator-value="1100" > to
<subclass name="Company" discriminator-value="1100 " >, it's OK.
