With a JComboBox you have to be careful that you don't run a query when just the cursor is moved up or down the list. If you want the listener to fire just when enter is pressed or the mouse is clicked, then do this:
//This stops events being fired when the cursor is used on the list
comboBox.putClientProperty("JComboBox.isTableCellEditor", Boolean.TRUE);You should also attach an event listener like this one:
comboBox.addActionListener(new ActionListener() {
               public void actionPerformed(ActionEvent evt) {
                        executeSomeQuery(comboBox.getSelectedItem().toString());               }
          });Or something similar to above, have a play around with it and it should work how you want it to.
