You appear to be creating a new JTable with each iteration of your loop through your result set, and this just doesn't make much sense. Would you have better luck if your JTable instead used a DefaultTableModel object for its data, and if you added a row of data to this model with each loop?

This and your other post suggest that you may benefit by going through much more of the Sun Swing tutorials before doing much more Swing coding.
