Bug fix related to CriteriaQuery (JPA) when using XML mappings -------------------------------------------------------------- Key: HHH-6100 URL: https://hibernate.onjira.com/browse/HHH-6100 Project: Hibernate ORM Issue Type: Patch Components: core Affects Versions: 3.6.2, 4.1.0 Environment: hibernate-(core, entitymanager...)-3.6.2.Final hibernate-jpa-2.0-api-1.0.0.Final MySQL 5.1 Spring 3.0.5.RELEASE Reporter: JOUFFRE Nelly Assignee: Strong Liu Priority: Critical Fix For: 4.1.1 Attachments: testmapping.zip Original Estimate: 1h Remaining Estimate: 1h Hi, I use XML mapping and wanted to implement the following query using CriteriaQuery. CriteriaBuilder cb = entityManager.getCriteriaBuilder(); CriteriaQuery<MyClass> cq = cb.createQuery(MyClass.class); Root<MyClass> objRoot = cq.from(MyClass.class); List<MyClass> results = entityManager.createQuery(cq).getResultList(); (Actually my query is more complex than that but it was the first step.) The first bug was that query generated the following jpql select generatedAlias0 from null as generatedAlias0 This was because the org.hibernate.mapping.PersistentClass.jpaEntityName attribute was not set Once I fixed it if tried to add a WHERE clause which was cq.where(cb.equal(objRoot.get("embeddablePkId").get("embeddablePkIdAttribute"), "valueToSearch")); which resulted into a NullPointerException because the org.hibernate.mapping.RootClass.declaredIdentifierProperty attribute was not set for simple and embeddable PK Theses 2 attributes are well set but only when using annotation mappings because they are set via the AnnotationBinder. In my case, with XML mapping, it calls the HbmBinder so these attributes are never set. Here are my bug fixes, hope this help.
