        try {
            Statement s = con.createStatement();
            ResultSet rs = s.executeQuery(sql);
            ResultSetMetaData metaDatos = rs.getMetaData();
                
            
            
        // Se obtiene el número de columnas.
        int numeroColumnas = metaDatos.getColumnCount();
        Object[] etiquetas = new Object[numeroColumnas];

        for (int i = 0; i < numeroColumnas; i++){
        // Nuevamente, para ResultSetMetaData la primera columna es la 1. 
        etiquetas[i] = metaDatos.getColumnLabel(i + 1); 
        }
        modelo.setColumnIdentifiers(etiquetas);
        
        
        
        while (rs.next()){
        Object [] fila = new Object[numeroColumnas];
        for (int i=0;i<numeroColumnas;i++)
            fila[i] = rs.getObject(i+1); // El primer indice en rs es el 1, no el cero, por eso se suma 1.

       modelo.addRow(fila); 
       cerrar();
       rs.close();
        }
        
        
        } catch (SQLException ex) {
            JOptionPane.showMessageDialog(null, ex);
        }
          
        
        
        
        
        }

1 SEARCH

1 RUN 1 TIME WHEN I OPEN THE SEARCH.JAVA WITH THE METODO ALL(); - WITH THIS WHEN THE FRAME GET OPEN THE DATA IS PREPARE AND IS IN THE TABLE

 public void all(){
       Usuarios u = new Usuarios();
      DefaultTableModel modelo = new DefaultTableModel();
      String consulta = "SELECT * FROM clientes";
        try {
            u.ListarClients(consulta, modelo);
        } catch (SQLException ex) {
            Logger.getLogger(BuscarCliente.class.getName()).log(Level.SEVERE, null, ex);
        }
     tabla.setModel(modelo);
    }

2.- SEARCH.. IN THE BOX I put the data to search and i click in search button, this button jave this method: IN THIS MOMMENT all is ok..

      DefaultTableModel modelo = new DefaultTableModel();
    String consulta = "SELECT * FROM clientes WHERE rfc LIKE '"+rfc.getText()+"%'";
        try {
            u.ListarClients(consulta, modelo);
        } catch (SQLException ex) {
            Logger.getLogger(BuscarCliente.class.getName()).log(Level.SEVERE, null, ex);
