I cannot get the exitApp() method to work, although it worked before I expanded on my code, I've been trying for hours to get it to work but no avail! The login button suceeds in opening the new frame but will not close the preious(login) frame. It did earlier till I added the validation method etc ....
Create only one JFrame as parent and for another Top-level Containers create only once JDialog (put there JPanel as base), and re-use that for another Action, then you only to remove all JComponents from Base JPanel and add there another JPanel
don't forget for as last lines after switch betweens JPanels inside Base JPanel
revalidate();
repaint();
you can pretty to forgot about that by implements CardLayout
