First, make sure that you have compiled MovingBall.java with the command javac MovingBall.java. Then the command appletviewer MovingBall.html should work fine on the arizona machines. On some machines, the DISPLAY variable needs to be changed from :0.0 to localhost:0.0. In principle, these are the same, but it appears to cause a problem with appletviewer. To change it, type the Unix command setenv DISPLAY “localhost:0.0”.
