The relevant code snippets are:
In MyServiceImpl -
@Repository
@Transactional
public MyServiceImpl ... {
protected EntityManager entityManager;
public void myMethod() {
Query query = entityManager.createQuery("select o from Myclass
o where o.title = :p1 and o.myProperty != :p2");
// bind params
query.getResultList();
// exception thrown unexpectedly
}
@PersistenceContext
public void setEntityManager(EntityManager entityManager) {
this.entityManager = entityManager;
}
}
In applicationContext.xml -
<!-- JPA EntityManagerFactory -->
<bean id="entityManagerFactory"
class="org.springframework.orm.jpa.LocalEntityManagerFactoryBean"
p:persistenceUnitName="main"/>
<!-- Transaction manager for a single JPA EntityManagerFactory
(alternative to JTA) -->
<bean id="transactionManager"
class="org.springframework.orm.jpa.JpaTransactionManager"
p:entityManagerFactory-ref="entityManagerFactory"/>
In persistence.xml -
<persistence-unit name="main">
<provider>org.datanucleus.store.appengine.jpa.DatastorePersistenceProvider</
provider>
<properties>
<property name="datanucleus.NontransactionalRead"
value="true"/>
<property name="datanucleus.NontransactionalWrite"
value="true"/>
<property name="datanucleus.ConnectionURL"
value="appengine"/>
</properties>
</persistence-unit>
Any help you provide is appreciated.
thanks,
