JTable - Can't add a TableModelListener

Question

Hi: I have created an Abstract jTable. When I add the line pointed out by this (<----)[near the middle], it won't compile and says that it cannot be applied here. I'd like to monitor the table for changes so I can programmatically adjust values in the table depending on what is input in certain table cells.
private class MyTableModelBase
      extends AbstractTableModel {
    public Object[][] rows;
    /** constructor */
    public MyTableModelBase()  {
      super();
      rows = new Object[7][8];
     * Gets the Column Name from the ColumnData Class.
     * @param index int
     * @return String
    public String getColumnName(int index) {
      return columnDefs[index].colTitle;
     * JTable uses this method to determine the default renderer/
     * editor for each cell.
    public Class getColumnClass(int c) {
      return getValueAt(0, c).getClass();
    public boolean isCellEditable(int row, int col) {
      if ( col != 6 ) { // Only allow Column 6 to be editable.
        return false;
      else {
            return true;
    public Object getValueAt(int row, int col) {
      return rows[row][col];
     * Don't need to implement this method unless your table's
     * data can change.
    public void setValueAt(Object value, int row, int col) {
      boolean DEBUG = false;
      String cellData = "";
      if (DEBUG) {
        System.out.println("Setting value at " + row + "," + col
                           + " to " + value
                           + " (an instance of "
                           + value.getClass() + ")");
      cellData = (String) value;
      rows[row][col] = cellData;
      fireTableCellUpdated(row, col);
     * Returns the total number of rows
     * @return the # of rows
    public int getRowCount() {
      return rows.length;
     * Returns the total number of columns in the table
     * @return the # of cols
    public int getColumnCount() {
      return columnDefs.length;
theTableModel = new MyTableModelBase();
jTable1 = new JTable(theTableModel);
TableColumn col = jTable1.getColumnModel().getColumn(6); // Overide Cell Editor
col.setCellEditor(new MyTableCellEditor());
jTable1.getModel().addTableModelListener(this); // <----- Won't let me do this
   * Class to handle CELL Editing in the Transaction Table.
  public class MyTableCellEditor
      extends AbstractCellEditor implements TableCellEditor {
    // This is the component that will handle the editing of the cell value
    JComponent component = new JTextField();
    // This method is called when a cell value is edited by the user.
    public Component getTableCellEditorComponent(JTable table, Object value,
                                                 boolean isSelected,
                                                 int rowIndex, int vColIndex) {
      // 'value' is value contained in the cell located at (rowIndex, vColIndex)
      selectedCellRow = rowIndex;
      cellCol = vColIndex;
      if (isSelected) {
        // cell (and perhaps other cells) are selected
      // Configure the component with the specified value
      ( (JTextField) component).setText( (String) value);
      // Return the configured component
      return component;
    // This method is called when editing is completed.
    // It must return the new value to be stored in the cell.
    public Object getCellEditorValue() {
      System.out.println("Row = " + selectedCellRow + " Col = " + cellCol);
     // User Selected CREDIT Amount Column.
        if (selectedCellRow > previousRow) {
          int i = selectedCellRow; // Row user selected.
          int rowIndex = 0;
          while (i > 0) {
            theTableModel.setValueAt("Skip", rowIndex, 0); // P/S column
            InArray[0] = "3"; // Send "SKIP" command
            HostCom.doAction("OpenItems", InArray, OutArray, DataArray);
            rowIndex++;
            i--;
        InArray[0] = "4"; // PAY Entry
        InArray[1] = ( (JTextField) component).getText();
        HostCom.doAction("OpenItems", InArray, OutArray, DataArray);
        System.out.println("Function return code = " + OutArray[0]);
        theTableModel.setValueAt(OutArray[13], selectedCellRow, 7); // Balance column
        theTableModel.setValueAt("Pay", selectedCellRow, 0); // P/S column
        jTextField1.setText("$ " + OutArray[14].trim()); // Applied Payment
        jTextField2.setText("$ " + OutArray[15].trim()); // Remaining Payment
        previousRow = selectedCellRow + 1; // Update row pointer
        // Check if we reached the end of the Transactions Table
        if (previousRow == 7) {
          previousRow = 0;
        // We do need to monitor the cursor location return value.
        if (OutArray[0].equals("6")) { // End of Table. Monies still available.
          SwingUtilities.invokeLater(getUserResponse1);
      return (OutArray[6]); // Update Credit Cell
  }

Hi: I have created an Abstract jTable.Why are you going to all this trouble.
Your TableModel doesn't do anything special so you can use the DefaultTableModel which will do everything you want.
