Try

DefaultTableModel tabModel = new DefaultTableModel() {
      public boolean isCellEditable(int row, int column) {
            return false;
      }
};
tabModel.addRow(new Object[] { "ROLLS", "CITY", "YEAR" });

Now use 'tabModel' to construct JTable

What is at Rolls.java line 47 ?
Maybe you use a Vector to represent the data and it is empty or not initialized.

Bye, Giant.

Set your column headings in the ctor, *not* using setValueAt()
Change your code to the following.

private JTable jTable1;
DefaultTableModel tabModel =new DefaultTableModel(new String[] { "ROLLS", "CITY", "YEAR"}, 0 );
jTable1 = new JTable(tabModel)
{
public boolean isCellEditable(int row, int column)
{
return false;
}
};
JScrollPane pane = new JScrollPane(jTable1);
pane.setBounds(100, 90, 320, 170);
getContentPane().add(pane);

Hello Dear;

I have got one row with names ROLLS, CITY, YEAR
using that Objects's code
private JTable jTable1;
DefaultTableModel tabModel =new DefaultTableModel(new String[] { "ROLLS", "CITY", "YEAR"}, 0 );
jTable1 = new JTable(tabModel)
{
public boolean isCellEditable(int row, int column)
{
return false;
}
};
JScrollPane pane = new JScrollPane(jTable1);
pane.setBounds(100, 90, 320, 170);
getContentPane().add(pane);

Now i want to add rows using Resultset. But i m got error.
i m using following code
this.tabModel.insertRow(a,new String[] { rs.getString("RFILE"),rs.getString("CITY"), rs.getString("PYEAR")});

CEHJ

Add a row using

tabModel.addtRow(new Object[] { rs.getString("RFILE"),rs.getString("CITY"), rs.getString("PYEAR")});

CEHJ

Typo:

>>addtRow

should be

addRow
