Estou tentando fazer um mapeamento com o OneToOne mais está sendo gerado um erro inesperado, esse relacionamento é entre o colaborador e o login. observe as classes de persistencias abaixo junto com os mapeamentos utilizados
@Entity
@Table(name = "login")
public class Login {
@EmbeddedId
private IdLogin idLogin;
private String Log_permissao;###############################
@Entity
@Table(name = "colaborador")
public class Colaborador implements Serializable{
private Long Col_codigo;
private String Col_nome;
private String Col_funcao;
private String Col_fone;
public Colaborador(){
}
#########################################
@Embeddable //Esta anotação indica que esta classe é um componete de outra, muito utilizado para representar um CHAVE COMPOSTA
public class IdLogin implements Serializable{
@Column(name = "Log_nome", nullable = false)
private String Log_nome;
@Column(name = "Log_senha", nullable = false)
private String Log_senha;
@OneToOne
@JoinColumn(name="Log_Col_codigo", insertable = true, updatable = true, nullable = false)
private Colaborador colaborador;

Sendo assim não consigo nem conectar com o banco tenho certeza que tem alguma coisa errada com anotação, mais o que estou fazendo de errado
já consegui mapear um relacionamento ternário mais estou apanhado para o OneToOne.
Pesso a ajuda de todos! estou aguardando. Obrigado!
