    Default Problem with DAL and BLL classes

    Hi

    i have 3 classes ( users, userDAL and UsersBLL)

    Everytime i trying to add record to my db i have null in all fields

    This is my UsersDAL method

    Java Code:

    public void criarUser(Users us) throws SQLException {
        String sqlCommand =
                "INSERT INTO USERS (UTLIZADOR, PASS, EMAIL, CARGO) VALUES('"
                + this.nome + "', '" + this.pass + "', '" + this.email + "', '" + this.cargo + "')";
        this.dbo.executeSQL(sqlCommand);
    }
    My UsersBLL

    Java Code:

    public class UsersBLL {
     
        UsersDAL us;
        DBAccessObj obj;
     
        public UsersBLL(){
     
            if(us == null){
                us = new UsersDAL();
            }
     
        }
     
        public void criarUser(Users users) throws SQLException{
     
            try
            {
                us.criarUser(users);
            }
            catch (Exception ex)
            {
                //tratamento de erro
                //tratarErro(ex);
     
                //erro para a camada superior.
                throw ex;
            }
        }

    and finally what i use to add records

    Java Code:

    private void btNovoActionPerformed(java.awt.event.ActionEvent evt) {                                       
            // TODO add your handling code here:
            String mens;
     
            UsersBLL b = new UsersBLL();
            try {
                txt_nome.getText();
                txt_pass.getText();
                txt_email.getText();
                combo.getSelectedItem().toString();         
                int resposta = JOptionPane.showConfirmDialog(null, "Os dados estão corretos?", "Aviso", JOptionPane.OK_CANCEL_OPTION);
                if (resposta == JOptionPane.OK_OPTION) {
                    b.criarUser(users);
                    mens = "Informação do User criada com sucesso!";
                    //javax.swing.JOptionPane.MessageDialog(null, mens, "Informação", javax.swing.JOptionPane.OK_OPTION);
                } else if (resposta == JOptionPane.CANCEL_OPTION) {
                }
    Is anythhing wrong in this code??
