Netbeans me lanza error de persistencia..

[Bellenger]

Hola, jeje nuevamente molestando, estoy utilizando los master/detaeil que viene en el netbeans (bindigns), y me lanza este error:

Código:

Exception in thread "AWT-EventQueue-0" javax.persistence.PersistenceException: No Persistence provider for EntityManager named sis_moniteroPU: Provider named oracle.toplink.essentials.PersistenceProvider threw unexpected exception at create EntityManagerFactory: 
oracle.toplink.essentials.exceptions.PersistenceUnitLoadingException
Local Exception Stack:

Exception Description: predeploy for PersistenceUnit [sis_moniteroPU] failed.

Utilice el asistente pero igual me lanza el error, alguien tendra un manualito o ejemplos de los Bindings que me esta dando mucha lata...
