O MangedBean
package pojo;
import javax.faces.bean.ManagedBean;
import javax.faces.bean.SessionScoped;
import javax.faces.context.FacesContext;
import pojo.Usuario;
import javax.faces.application.FacesMessage;
@ManagedBean
@SessionScoped
public class UsuarioManagedBean {
private Usuario usuario;
private String login,senha;
private Validador validador;
public UsuarioManagedBean(){
usuario=new Usuario();
}
public Usuario getUsuario(){
return usuario;
}
public void setUsuario(Usuario usuario){
this.usuario=usuario;
}
public String logar(){
validador=new Validador();
if(validador.validar(usuario.getLogin(),usuario.getSenha())){
return "OK";
}
FacesMessage msg=new FacesMessage("Usuario/senha invalidos");
FacesContext.getCurrentInstance().addMessage("form", msg);
return "";
}
public String deslogar(){
FacesContext context=FacesContext.getCurrentInstance();
context.getExternalContext().getSessionMap().remove(usuario.getLogin());
context.getExternalContext().getSessionMap().remove(usuario.getSenha());
return "logout";
}
}A classe usuario
package pojo;
public class Usuario {
private String login,senha;
public String getLogin(){
return login;
}
public void setLogin(String login){
this.login=login;
}
public String getSenha(){
return senha;
}
public void setSenha(String senha){
this.senha=senha;
}
}O validador
package pojo;
import java.sql.*;
import java.sql.SQLException;
public class Validador {
private String senha;
public boolean validar(String usuario,String pass) {
BD bd=new BD();
Boolean resultado=false;
if(bd.getConnection()){
try {
String sql="select user,pwd from usuarios where user=?";
PreparedStatement statement=bd.connection.prepareStatement(sql);
statement.setString(1,usuario);
ResultSet resultSet=statement.executeQuery();
if(resultSet.next()){
senha=resultSet.getString("pwd");
if(pass.equals(senha)){
System.out.println("login e usuario valido");
resultado=true;
}
}
System.out.println("Nao encontrado");
bd.close();
}
catch(SQLException erro){
System.out.println("Erro: "+erro);
}
}
return resultado;
}
}e finalmente a classe responsavel por connectar no mysql
package pojo;
import java.sql.*;
public class BD {
public Connection connection = null;
private final String DRIVER = "com.mysql.jdbc.Driver";
private final String DBNAME = "locadora";
private final String URL = "jdbc:mysql://localhost:3306/" + DBNAME;
private final String LOGIN = "root";
private final String SENHA = "teste";
/**
* metodo que faz conexao com o banco de dados
* retorna true se houve sucesso, ou false em caso negativo
*/
public boolean getConnection() {
try {
Class.forName(DRIVER);
connection = DriverManager.getConnection(URL, LOGIN, SENHA);
System.out.println("Conectou");
return true;
} catch (ClassNotFoundException erro) {
System.out.println("Driver nao encontrado " + erro.toString());
return false;
} catch (SQLException erro) {

return false;
}
}
public void close() {
try {
connection.close();
System.out.println("Desconectou");
} catch (SQLException erro) {}
