#85 Stuff Stuff in JARs

HACK

To actually start this whole class, you simply call the launch method like

this:

public static void main(String[] args) {

new SingleLauncherApplication( ).launch(args);

}

The first time the program is launched it will create the window with the

label. For example, running the following command would result in

Figure 11-8.

java -cp . SingleLauncherApplication 'anonymous'

Now, start the program again, with the first running:

java -cp . SingleLauncherApplication 'perspicacity'

Instead of creating a new window, the program will contact the original (and

still running) instance and change the text to Figure 11-9.

Stuff Stuff in JARs Hack #85

Hide images, sounds, and more inside JAR files.

Does your application need a special installer? Do you have to put images,

sounds, icons, and properties all in their own folders or other special loca-

tions relative to your application? Does your application launch with a .sh

script on Unix or a .bat on Windows?

You do? Really? I was just speaking rhetorically. I kind of figured everyone

was using JARs by now.
