[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-6039) jpaEntityName not set when using Hibernate mapping

[Scott Basinger (JIRA)]

    [ http://opensource.atlassian.com/projects/hibernate/browse/HHH-6039?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=45265#comment-45265 ] 

Scott Basinger commented on HHH-6039:
-------------------------------------

After a little more testing, the setting of jpaEntityName should be done in bindRootClass, handleSubclass, handleJoinedSubclass and handleUnionSubclass by adding a line similar to this:

subclass.setJpaEntityName(subclass.getNodeName());

Then the bindSimpleID and bindCompositeId methods would have the line: 

			entity.setDeclaredIdentifierProperty(prop);

Then we get rid of our UnknownProperty and generatedAlias null issues. (So far).

> I'm trying to run the following query
> CriteriaBuilder cb = entityManager.getCriteriaBuilder();
> CriteriaQuery<Qualifier> cq = cb.createQuery(Qualifier.class);
> Root<Qualifier> qualifRoot = cq.from(Qualifier.class);
> List<Qualifier> results = entityManager.createQuery(cq).getResultList();
> The Qualifier class is mapped using Hibernate hbm.xml mapping (see attachement)
> The entityManagerFactory is configured using a Spring class
> <bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
> ...
> </bean>
> This Criteria query throws the exception: org.hibernate.hql.ast.QuerySyntaxException: unexpected token: null near line 1, column 29 [select generatedAlias0 from null as generatedAlias0]
> The FROM clause, which here is null, is built using the EntityType.jpaEntityName property which value comes from PersistentClass.jpaEntityName property. But this property is never set when context is loaded to build the Metamodel.
> Is this property not set because the mapping is an hibernate mapping and not a JPA one ? or is it a bug ?
