Colega, posta ai o trecho que está salvando o objeto ; o trecho que pede sessao e a classe do seu objeto que está sendo persistido…

[borges.com]

segue o meu code

as secoes dohibernate são carregadas diretamente pelo spring onde tenho um dao genérico que faz todas as operacoes

Code do Bean usuario

package br.com.euarremato.bean.Usuario;

import java.io.Serializable;
import java.util.Date;
import java.util.List;

import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.OneToMany;
import javax.persistence.SequenceGenerator;
import javax.persistence.Table;

@Entity
@Table(name="usuario")
@SequenceGenerator(name = "usuario_sequence", sequenceName = "usuario_sequence",allocationSize=0,initialValue=1)
public class Usuario implements Serializable{

	@Id
	@GeneratedValue (strategy = GenerationType.SEQUENCE, generator = "usuario_sequence")
	@Column(name="id")	
	private Long id;
	
	private String cep;
	@Column(length=9999)
	private String cidade;
	@Column(length=9999)
	private String estado;
	@Column(length=9999)
	private String pais;
	@Column(length=9999)
	private String rua;
	@Column(length=9999)
	private String complemento;
	@Column(length=9999)
	private String tpRua;
	private boolean bloqueado;
	private String celular;
	private String cpf;
	private String chaveAcesso;
	private Date dataNasc;
	private Date dtOperacao;
	private String estadoCivil;
	private Funcao funcao;
	@OneToMany
	private List<Credito> pctUsuario;
	private String login;
	private String mail;
	private String nome;
	private String numeroCasa;
	private int qtdeLances;
	private String senha;
	private Character sexo;
	private String sobreNome;
	private Fidelidade fidelidade;
	private boolean verificado;
	@Column(nullable=true)
	private boolean spam;
	@Column(nullable=true)
	private Usuario indicadoPor;
	@Column(nullable=true)
	private boolean indicacaoPendente;

         public Usuario() {}


         //geteres e seteres

}

metodo do meu controller

	public ModelAndView cadastroSaveEdit(HttpServletRequest req,HttpServletResponse res,Usuario usuario) throws ParseException {
		Map<String, Object> model = new HashMap<String, Object>();
		DateFormat formatter = new SimpleDateFormat("dd/MM/yyyy");  
		Date dtnascimento = (Date)formatter.parse(req.getParameter("dia")+"/"+req.getParameter("mes")+"/"+req.getParameter("ano"));  
		usuario.setDataNasc(dtnascimento);
		if(!req.getParameter("funcaoid").equals("0")){usuario.setFuncao(funcaoManager.getById(Long.parseLong(req.getParameter("funcaoid"))));}

		usuarioManager.update(usuario);
		
//		req.getSession().removeAttribute("usuario");
//		req.getSession().setAttribute("usuario", usuario);
		req.setAttribute("msg", "cadastro editado com sucesso");
		model.put("menu","02");
		model.put("temtitulo","sim");
		model.put("feedback", "Minha Conta no EuArremato.com");
		model.put("titulo" ,"Meus Dados");
		model.put("temmenu", "sim");
		model.put("tpnenulateral" ,"user");
		model.put("tituloInterno", "");

		return new ModelAndView("usuario/MinhaConta",model);
	}

code do spring e do hibernate

metodo que pega a session do banco 

private SessionFactory sessionFactory;

	@SuppressWarnings("unchecked")
	public ManagerImpl(SessionFactory sessionFactory) {
		persistentClass = (Class<T>) ((ParameterizedType) getClass()
				.getGenericSuperclass()).getActualTypeArguments()[0];
		this.sessionFactory = sessionFactory;
	}

protected Session getSession() {
		return sessionFactory.getCurrentSession();
	}



//metodo genérico de update
	public void update(T entity) {
		getSession().update(entity);
	}

[Victor_Neves]

cara, eu nao entendo nada de spring, mas eu nao vi no seu codigo o trecho em que voce pede uma transaçao, um beginTransection().
antes de persistencia, update ou delete tem que ser aberta uma transaçao…
