Dears,
I am working on small web application using JPA with TopLink and JSF.
when I use dependency injection
@PersistenceUnit(unitName = "mufixPU")
private EntityManagerFactory emf;
everything works fine. but when I use
Persistence.createEntityManagerFactory("mufixPU").createEntityManager();
I got this error:
Exception [TOPLINK-8006] (Oracle TopLink Essentials - 2006.8 (Build 060830)): oracle.toplink.essentials.exceptions.EJBQLException
Exception Description: A problem was encountered resolving the class name - The descriptor for [Book] was not found.
this means that entity classes can't be found?
I need to use the second method? any clue?
Thanks in advance
BISO

I see that the application server is having problems deploying/loading the persistence unit.
Can you advise us with your persistence.xml file and applicationContext if you have it.
