java.lang.ClassNotFoundException for my generic DAO

I create a generic DataAccessObject and try to save a data in my database

HibernateDAO.java

/*
* To change this template, choose Tools | Templates
* and open the template in the editor.
*/
package br.salesianos.dao;
import br.salesianos.db.CriadorDeSessao;
import java.io.Serializable;
import java.util.List;
import javax.faces.bean.ManagedBean;
import org.hibernate.Session;
public class HibernateDAO<T> {
private Class<T> classe;
public HibernateDAO(Class<T> classe) {
super();
this.classe = classe;
}
public void atualizar(T bean) {
Session session = CriadorDeSessao.getSession();
session.beginTransaction();
session.update(bean);
session.getTransaction().commit();
}
public void excluir(T bean) {
Session session = CriadorDeSessao.getSession();
session.beginTransaction();
session.delete(bean);
session.getTransaction().commit();
}

}
public void salvar(T bean) {
Session session = CriadorDeSessao.getSession();
session.beginTransaction();
session.save(bean);
session.getTransaction().commit();
}
}

I use JSF and Hibernate in my application.

This code works perfect when i call him inside netbeans like a desktop app

but when i try to use him inside a JSF app, he give me a error

this is the ManagedBean that i use to save data through xhtml file

GravaCidade.java

package br.salesianos.db;
import br.salesianos.dao.HibernateDAO;
import br.salesianos.modelo.Cidade;
import br.salesianos.modelo.Estado;

import javax.faces.bean.ManagedBean;
import org.hibernate.*;

public class GravaCidade
{
private int est_id;
private String cid_nome;
private List<Estado> estados;
public String gravar()
{
HibernateDAO<Cidade> cidadeDAO = new HibernateDAO<Cidade>(Cidade.class);
Estado obj_estado = new Estado();
obj_estado.setEst_id(1);
Cidade obj_cidade = new Cidade();
obj_cidade.setCid_nom("ffffddd");
obj_cidade.setEstado(obj_estado);
cidadeDAO.salvar(obj_cidade);
return "sucesso";
}
/**
* @return the est_id
*/
public int getEst_id() {
return est_id;
}
/**
* @param est_id the est_id to set
*/
public void setEst_id(int est_id) {
this.est_id = est_id;
}
/**
* @return the cid_nome
*/
public String getCid_nome() {
return cid_nome;
}
/**
* @param cid_nome the cid_nome to set
*/
public void setCid_nome(String cid_nome) {
this.cid_nome = cid_nome;
}
}

why this don't work in JSF app?

How to optimize code using JSF

Ok, you are right, I will follow the java coding standards, i will rename the "seuManagedBean" to "SeuManagedBean", but I don't know how implement faces-config.xml, how i can implement that?

Another thing, take a look in code below: it's the same logic as the "SeuManagedBean":

package br.salesianos.lista;
import br.salesianos.db.*;
import br.salesianos.modelo.*;
import java.util.List;
import javax.faces.bean.ManagedBean;
import org.hibernate.Session;
@ManagedBean
public class ListaEstado {
private List suaLista;
private List nossaLista;
//private List listaCidade;
//private List listaPessoa;
public ListaEstado() {
filtrar();
filtraCidade();
}
private void filtraCidade() {
Session sessao = CriadorDeSessao.getSession();
nossaLista = (sessao.createCriteria(Pessoas.class).list());
sessao.close();
}
public void filtrar() {
Session sessao = CriadorDeSessao.getSession();
suaLista = (sessao.createCriteria(Estado.class).list());
sessao.close();
}
/**
* @return the suaLista
*/
public List getSuaLista() {
return suaLista;
}
/**
* @param suaLista the suaLista to set
*/
public void setSuaLista(List suaLista) {
this.suaLista = suaLista;
}
/**
* @return the nossaLista
*/
public List getNossaLista() {
return nossaLista;
}
/**
* @param nossaLista the nossaLista to set
*/
public void setNossaLista(List nossaLista) {
this.nossaLista = nossaLista;
}
}

I use the same logic as the "SeuManagedBean", but they call two methods

and each of them call a diferent criteria

This way, everytime i need to populate a selectonemenu, the code will call all methods(each accesses the database to retrieve the records), my application may become slow?

I understand your idea about the config in faces-config.xml, but i don't know how to implement.

Could you help?

This in my xhtml file that i use with ListaEstado

How to optimize code using JSF

I am creating an application using Hibernate and JSF, but at certain times to write data to some tables, I need to pull information stored in other tables

this is the ManagedBeans that I use to pull data from a particular table in my database

but where the line has the following code

I use a fixed class, someone would have an idea how I could pass it dynamically, I ask this because otherwise I'll have to create a ManagedBean for each class that I need to list the database

sorry for the bad english...
