JTable problem with TableModel

Question

This is basicly what I do:
MyTableModel aTableModel = new MyTableModel();
aTable = new JTable(aTableModel);
aTableModel.setData(data, columnNames);The setData method of my MyTableModel class:
public void setData(Object[][] data, String[] columnNames) {
  this.data = data;
  this.columnNames = columnNames;
  this.fireTableDataChanged();
}It just shows an empty scrollpane, no columnnames or nothing..

Answer 1

ok, im a bit lost here. Where exactly should I call super.tableChanged(...) ? The entire myTableModel class:
private class MyTableModel extends AbstractTableModel {
        private String[] columnNames = null;
        private Object[][] data = null;
        public MyTableModel() {
            columnNames = new String[0];
            data = new Object[0][0];
        public MyTableModel(Object[][] data, String[] columnNames) {
            this.columnNames = columnNames;
            this.data = data;
        public int getColumnCount() {
            return columnNames.length;
        public int getRowCount() {
            return data.length;
        public String getColumnName(int col) {
            return columnNames[col];
        public Object getValueAt(int row, int col) {
            return data[row][col];
        public Class getColumnClass(int c) {
            return getValueAt(0, c).getClass();
        public boolean isCellEditable(int row, int col) {
            if (col < 1) {
                return false;
            } else {
                return true;
        public void setData(Object[][] data, String[] columnNames) {
            this.columnNames = columnNames;
            this.data = data;
            this.fireTableDataChanged();
        public void setValueAt(Object value, int row, int col) {
            data[row][col] = value;
            fireTableCellUpdated(row, col);
