Note the code used to allow the applet to run as an application as well, especially the main
method beginning at line 157 of Listing 7.6. The parameters and the
getCodebase
method (line
119 of Listing 7.6) supply directory change according to whether the
InstallerApplet
is run
as an applet or an application (method
getParameter
at line 22 of Listing 7.6).
Ascreenshot from the installer applet launched as an application is shown in Figure 7.7.
