Bom, quando eu vou persistir uma classe que não depende de outra, ocorre tudo normal.
Mas, no caso, uma LOCADORA, um dependente tem de está associado a um cliente. Ai quando eu vou persistir o dependente da erro.
Vamos aos códigos e ao erro:

jpaDAO 
package br.sicofi.locadora.dao;

	private EntityManagerFactory emf;  
	private EntityManager em;  
	private EntityTransaction et;  

	public jpaDAO() {  
		emf = Persistence.createEntityManagerFactory("locadora");  
		em = emf.createEntityManager();  
		et = em.getTransaction();  
	}  

	public EntityManagerFactory getEmf() {  
		if(emf == null)
			emf = Persistence.createEntityManagerFactory("locadora");

	}  

	public EntityManager getEm() {

Tenta isso:

@OneToMany(cascade = { CascadeType.ALL }, fetch = FetchType.EAGER)
	@Cascade(value = { org.hibernate.annotations.CascadeType.SAVE_UPDATE,
			org.hibernate.annotations.CascadeType.DELETE_ORPHAN })

e em dependentes,retira esse trecho:

@ManyToOne(fetch = FetchType.EAGER,  
            cascade={CascadeType.PERSIST, CascadeType.MERGE})  
     @JoinColumn(name="cliente")  
     private Cliente cliente;

porém dessa forma, será apenas unidirecional o acesso…não sei se resolve o seu problema.

Bom, vlw por responder.

Mas, como você disse, vai ficar apenas unidirecional, ai num pode ;(

Quando eu tava usando sessionFactory e talz, taava dando tudo certinho. Ai tive de mudar pra EntityManager e ta dando esse erro :frowning:

cheat.

E
ednilo.pinheiro

Quando eu desabilitei o <f:converter> deu erro de conversão e quando da habilitado da esse erro do NullPointerException.
Será minha conversão errada?

Alguém helps 0/
