Eai pessoal,

este eh o metodo que eu executo e eh onde da o erro:

@Restrito
	@Put @Path("/{pessoa.usuario.login}/alterarPessoa")
	public void alterar(Pessoa pessoa, String cadastroAtivo, String dataCadastro, String qtdAcessos, String idCripto) {

		// cache do ID criptografado para o metodo validarPessoa
		this.idCripto = idCripto;
		
		Long id = null;
		try{
			id = Long.parseLong(DecryptData.decryptData(idCripto, CreateAndSaveAESKey.AES_SECRET_KEY_FOR_ID));
		}catch (NoSuchAlgorithmException noSuchAlgo) {
			System.out.println(" Nao existe tal algoritmo: " + noSuchAlgo.getMessage());
		}catch (NoSuchPaddingException noSuchPad) {
			System.out.println(" Nao foi preenchido: " + noSuchPad.getMessage());
		}catch (InvalidKeyException invalidKey) {
			System.out.println(" Codigo invalido: " + invalidKey.getMessage());
		}catch (BadPaddingException badPadding) {
			System.out.println(" Preenchido errado: " + badPadding.getMessage());
		}catch (IllegalBlockSizeException illegalBlockSize) {
			System.out.println(" Tamanho do bloco ilegal: " + illegalBlockSize.getMessage());
		}catch (InvalidAlgorithmParameterException invalidParam) {
			System.out.println(" Parametro invalido: " + invalidParam.getMessage());
		}catch (Exception e) {
			System.out.println(" Erro: " + e.getMessage());
		}
		
		Cidade cidade = cidDao.consultar(pessoa.getCidade().getId());
		pessoa.setCidade(cidade);
		
		Pessoa recuperada = pesDao.consultar(id);
		pessoa.setId(id);
		pessoa.setCadastroAtivo(recuperada.getCadastroAtivo());
		pessoa.setDataCadastro(recuperada.getDataCadastro());
		pessoa.setQtdAcessos(recuperada.getQtdAcessos());
		pessoa.setUsuario(recuperada.getUsuario());
		
		validarPessoa(pessoa);
		pesDao.alterar(pessoa); 
		result.redirectTo(this).listar();
	}

este eh o erro que aparece no console do eclipse:

pelo que entendi eu posso ter mapeado errado.. vou colocar minha classe Pessoa e Usuario para vc entender como foram mapeados:

@Entity
public class Pessoa implements Serializable {

	@Id
    @SequenceGenerator(name="PessoaId",allocationSize=1, sequenceName="PessoaId")
    @GeneratedValue(generator="PessoaId", strategy=GenerationType.SEQUENCE)
	private Long id; 
	
	@Version
	private Long versao;
	
	@NotEmpty(message="O nome deve ser informado!") 
	@Length(min=3, message="O nome deve conter mais de 3 caracteres!")
	private String nome; 
	
	@NotEmpty(message="O e-mail deve ser informado!")
	@Length(min=3, max=80, message="O e-mail deve conter entre 3 e 80 caracteres!")
	@Email(message="Informe um e-mail valido!")
	private String email;
	
	@Length(min=9, max=9, message="O CEP deve conter 9 caracteres!")
	@NotEmpty(message="O CEP deve ser informado!") 
	private String cep;
	
	@Length(min=6, max=8, message="O tipo de pessoa deve ser ou Fisica ou Juridica!")
	@NotEmpty(message="O tipo da pessoa deve ser informado!") 
	private String tipoPessoa;
	
	private Long qtdAcessos;
	
	/**
	 * A data de cadastro deve ser inserida automaticamente pelo sistema.
	 */
	@NotNull(message="A data de cadastro deve ser informada!")
	@Temporal(value=TemporalType.DATE)
	private Date dataCadastro;
	
	private Boolean cadastroAtivo;
	
    @OneToOne(mappedBy="pessoa")
    private Usuario usuario;

	/**
     * Cidade da pessoa (agrega&ccedil;&atilde;o). <br/>
     * Muitas pessoas para uma cidade.
     */
    @ManyToOne
    @NotNull(message="A cidade deve ser informado!")
    private Cidade cidade;

@Entity
public class Usuario implements Serializable {

	@Id
    @SequenceGenerator(name="UsuarioId",allocationSize=1, sequenceName="UsuarioId")
    @GeneratedValue(generator="UsuarioId", strategy=GenerationType.SEQUENCE)
    private Long id;
	
	@Version
	private Long versao;
    
	@NotEmpty(message="O login deve ser informado!")
    private String login;
	
	@NotEmpty(message="O password deve ser informado!")
    private String password;
    
    /**
     * Pessoa do usuario (agrega&ccedil;&atilde;o). <br/>
     * Uma pessoa para um usuario.
     */
    @OneToOne(cascade=CascadeType.ALL, optional=false, fetch=FetchType.EAGER, orphanRemoval=true)
    @PrimaryKeyJoinColumn
    @NotNull(message="A pessoa deve ser informada!")
    private Pessoa pessoa;

bem, eu tenho uma ligaçao um para um entre usuario e pessoa.. quando eu crio um objeto pessoa ela eh adicionada ao atributo pessoa no objeto usuario e o usuario eh persistido..

Para eu atualizar os atributos de pessoa devo fazer da mesma forma como faço para cria-los? ou seja, adicionar a pessoa alterada ao usuario e atualizar o usuario?

Lucas_Cavalcanti 7 de ago. de 2012

esse erro é por causa do lock otimista… vc tem um atributo com @Version… na hora de fazer qqer coisa com os objetos com isso vc tem que estar com a mesma versão que tá no banco…

ou seja, não basta só setar o id do objeto, vc tem que setar a versao também…

geralmente vc consegue fazer isso buscando cada relacionamento no banco (ou só os caras com @Version), com o session.load

tefo 7 de ago. de 2012

entao vc quer dizer que eu tenho que recuperar o atributo versao, setar no objeto pessoa a ser atualizado e persisti-lo com a mesma versao que esta no banco?

tefo 7 de ago. de 2012

era isso mesmo!

adicionei a seguinte linha no meu metodo antes de persistir e funcionou:pessoa.setVersao(recuperada.getVersao());
obrigado pela força ai Lucas!!

Lucas_Cavalcanti 7 de ago. de 2012

se pessoa é o objeto que vc tá salvando, não faça isso!!!

senão vc tá zuando todo o esquema de lock…

vc precisa no formulário colocar um input hidden com a versão:

<input type="hidden" name="pessoa.versao" value="${pessoa.versao}" />

desconfiei desde o principio… :lol:
