And what other things else did you see when you ran your program?

[kiko11]

only the records but there is no column name..

It is by design when you use JTable. If you want the header row of the table to be display, add a JScrollPane to wrap around your table instead. However, doing so will force you to set up a correct size for the table. If you just simply add the JScrollPane to it as of now, you would see that the table is displayed much smaller than it should be.

By the way, you should add the closing window right when you create your frame. If you don't, your program will do nothing after a user click "close" the window.

JScrollPane scrPane = new JScrollPane(tblOne);
  .
  .
  .
// instead of adding table, adding scroll pane here
addComponent(scrPane, 4, 0, a_width_number, a_height_number);
  .
  .
closeWindow();
  .
