[joede.fadel]

faltou fazer o caminho inverso do relacionamento

@JoinColumn(name = "empresa", referencedColumnName = "idempresa") @ManyToOne private Empresa emprasa;

[Naruto]

pode me dizer como eo faço isso??

Obrigado

[joede.fadel]

Opa

eu naum tinha visto que vc ja tinha colocado o inverso, a unica coisa que vc fez foi errar o nome no relacionamento

//ao invez de:
@OneToMany(cascade = {CascadeType.PERSIST, CascadeType.MERGE}, mappedBy = "empresa") 
private Collection<Usuario> usuarios = new ArrayList<Usuario>(); 
/*coloque assim
* OBS: o mappedBy é referente ao atributo da Classe que vc está referenciando
*/
@OneToMany(cascade = {CascadeType.PERSIST, CascadeType.MERGE}, mappedBy = "idempresa") 

private Collection<Usuario> usuarios = new ArrayList<Usuario>(); 

[Naruto]

agora mudo o erro?

[joede.fadel]

em que momento ta acontecendo esse erro, na hora que você executa a pagina ou na hora que vc executa o batão?

[Naruto]

na hora que eu clico no botão… parece que é na hroa de executar a sql
pois acontece a mesma coisa com a pagina de listar ou seja quando vai fazer o select
agora a pagina de cadastrar é executada normalmente
a unica coisa é que quando eo volto para a pagina de menu as imagens não são carregadas… vc sabe porque?
vlw

[Naruto]

Cara beleza???
resolvido aqui cara

tive que comentar essas linhas

// @OneToMany(cascade = {CascadeType.PERSIST, CascadeType.MERGE}, mappedBy = “empresa”)
// private Collection usuarios = new ArrayList();

// public Collection getUsuarios() {
// return usuarios;
// }
//
// public void setUsuarios(Collection usuarios) {
// this.usuarios = usuarios;
// }

e neste select tive que muda a tabela empresa para Empresa

public static List recuperarTodos() {
conectar();
List empresas = em.createQuery(“select emp from Empresa as emp order by emp.razaonome”).getResultList();
desconectar();
return empresas;
}

agora e aquele problema das imagens não carregar?? vc tem ideia?
