Hi, I can't use addRow in JTable

Question

Hi, I can't use addRow in tableModel1.addRow. I am new in Java
here some code
public class Class1 extends JInternalFrame implements TableModelListener
public Class1(Connection srcCN, JFrame getParentFrame) throws SQLException
    try
    cnCus = srcCN;
          stCus = cnCus.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE,
                    ResultSet.CONCUR_UPDATABLE);
          strSQL = "SELECT * FROM customer ORDER BY n_customer ASC";
    rsCus = stCus.executeQuery(strSQL);
      jbInit();
    catch(Exception e)
      e.printStackTrace();
  private void jbInit() throws Exception
    jScrollPane1.getViewport().add(jTable1, null);
    DefaultTableModel tableModel1 = MyModel();
    this.setClosable(true);
    this.setTitle("REVISION");
    this.setMaximizable(true);
    this.setSize(new Dimension(800, 600));
    this.setResizable(true);
    this.setIconifiable(true);
    this.addKeyListener(new java.awt.event.KeyAdapter()
        public void keyPressed(KeyEvent e)
          this_keyPressed(e);
private DefaultTableModel MyModel(){
  DefaultTableModel m = new DefaultTableModel(){
  public void setValueAt(Object value, int iRows, int iCols) {
                    try {
                         rsCus.absolute(iRows + 1);
                         rsCus.updateString(iCols + 1, value.toString());
                         rsCus.updateRow();
                         super.setValueAt(value, iRows, iCols);
                    } catch (SQLException e) {
               public boolean isCellEditable(int iRows, int iCols) {
                    if (iCols == 0)
                         return false;
                    if (iCols == 1)
                         return false;
                    return true;    
           public void addRow(Vector data){} 
m.setDataVector(Content, ColumnHeaderName);
return m;
private void this_keyPressed(KeyEvent e)
tableModel1.addRow(new Vector[]{"r5"});

Here is an example of building a DefaultTableModel using the data in a ResultSet:
import java.awt.*;
import java.io.*;
import java.sql.*;
import java.util.*;
import javax.swing.*;
import javax.swing.table.*;
public class TableFromDatabase extends JFrame
     public TableFromDatabase()
          Vector columnNames = new Vector();
        Vector data = new Vector();
        try
            //  Connect to the Database
            String driver = "sun.jdbc.odbc.JdbcOdbcDriver";
//            String url = "jdbc:odbc:Teenergy";  // if using ODBC Data Source name
            String url =
                "jdbc:odbc:Driver={Microsoft Access Driver (*.mdb)};DBQ=c:/data/database.mdb";
            String userid = "";
            String password = "";
            Class.forName( driver );
            Connection connection = DriverManager.getConnection( url, userid, password );
            //  Read data from a table
            String sql = "Select * from Page";
            Statement stmt = connection.createStatement();
            ResultSet rs = stmt.executeQuery( sql );
            ResultSetMetaData md = rs.getMetaData();
            int columns = md.getColumnCount();
            //  Get column names
            for (int i = 1; i <= columns; i++)
                columnNames.addElement( md.getColumnName(i) );
            //  Get row data
            while (rs.next())
                Vector row = new Vector(columns);
                for (int i = 1; i <= columns; i++)
                    row.addElement( rs.getObject(i) );
                data.addElement( row );
            rs.close();
            stmt.close();
        catch(Exception e)
            System.out.println( e );
        //  Create table with database data
        JTable table = new JTable(data, columnNames);
        JScrollPane scrollPane = new JScrollPane( table );
        getContentPane().add( scrollPane );
        JPanel buttonPanel = new JPanel();
        getContentPane().add( buttonPanel, BorderLayout.SOUTH );
    public static void main(String[] args)
        TableFromDatabase frame = new TableFromDatabase();
        frame.setDefaultCloseOperation( EXIT_ON_CLOSE );
        frame.pack();
        frame.setVisible(true);
