I am new to Macs and am trying to run 1.4.1 apps from the terminal. javac myapp.java java myapp It uses java from 1.4.1 and the little java icon opens in the dock but nothing else happens and when I right click on the icon it offers force quit. The app is a simply JOptionPane Hello World so it shouldnt take long. println Hello World works fine. My applets work great in the browser. Any help would be appreciated.
