This applet runs without problem in the appletviewer and the two browsers, but
only
if both applet fi le and image fi le are in the same directory as the associated
HTML fi le. (Output is shown in Figs.
12.10
and
12.11
.) If the fi les are in different
directories, a security exception is generated. This would appear to make the use of
a path redundant, of course. Indeed, it turns out that using the string “fi le:///d:earth.
gif” works just as well as using the full path “fi le:///d:/Applet Stuff/Pre-Swing/earth.
