implement
#CallByReference
#Stateless(mappedName = "cliente")
public class ClienteDAOBean implements ClienteDAOLocal, ClienteDAORemote {
#PersistenceUnit(unitName = "Persistence-ejbPU")
private EntityManagerFactory emf;
public Clientes find(Integer codCliente) throws Exception {
Clientes cliente = null;
EntityManager em = emf.createEntityManager();
try {
javax.persistence.Query q = em.createNamedQuery("Clientes.findByCodCliente").setParameter("codCliente", codCliente);
cliente = (Clientes) q.getSingleResult();
} catch (Exception e) {
throw e;
} finally {
em.close();
return cliente;
}
}
}
Pero al iniciar la aplicación el log arroja este error:
No persistence unit named 'Persistence-ejbPU' is available in scope Persistence-ejbPU.jar
was previously using a persistence.xml file but needed the name of the datasource out dynamic

Answer 1

Simply replace ref with value. Use:
<property name="persistenceUnitName" value="Persistence-ejbPU" />
instead of:
<property name="persistenceUnitName" ref="Persistence-ejbPU"/>
If you are having still problem then I would implement my own LocalContainerEntityManagerFactoryBean class which extends from AbstractEntityManagerFactoryBean so you can override setPersistenceUnitName then see what is going on.
