Hi
I am trying to retrieve all instances of an entity called Referral.
I am using Spring to create instances of my EJB 3 interface class called ReferralSessionLocal. I use Hibernate 3.3, hibernate-jpa-2.0-final.jar and the Oracle database, running on WebSphere 7 and Windows XP.
I am getting the following exceptions:

@PersistenceContext
private EntityManager entityManagerFactory;
void setEntityManager(EntityManager entityManagerFactory) {
this.entityManagerFactory = entityManagerFactory;
}
private EntityManager getEntityManager() {

}
Referral referral;
public ReferralDAO(){
}
@SuppressWarnings("unchecked")
public List<Referral> findAllReferrals() throws ReferralServicesException{
javax.persistence.Query query = entityManagerFactory.createQuery("SELECT ref FROM com.att.referraltracker.dto.referral.Referral ref ORDER BY ref.id");
logger.info("ReferralDAO: the query string in findAllReferrals() is " + query.toString());
try {
referralsList2 = (List<Referral>)query.getResultList();
} catch (Exception ex) {
ex.printStackTrace();
}
//String[] stringArray = (String[])validPapers.toArray(new String[validPapers.size()]);
return referralsList2;
}
}
The exception is pointing to the query.getResultSet statement, but I do not understand what is wrong with the query.
I have all the database tables in Oracle.
Thanks in advance
