[i]Sorry for bringing in confusion.
I can successfully instantiate EntityManager for OrderPU, but execution fails when I try to make a query:[/i]
@PersistenceContext(unitName="OrderPU")
EntityManager em;
...
public List findAll() {
Query q = em.createQuery("select object(o) from Line as o");
...
}
[i]with the following exception:[/i]
Caused by: javax.ejb.TransactionRolledbackLocalException: Exception thrown from bean; nested exception is: javax.persistence.PersistenceException: Exception [TOPLINK-28013] (Oracle TopLink Essentials - 2006.8 (Build 060830)): oracle.toplink.essentials.exceptions.EntityManagerSetupException
