For a real-world example,

I think you can fairly easily create a small application to demonstrate your options here. With a Info.plist including

	<dict>
		<key>ClassPath</key>
		<string>$JAVAROOT</string>
		<key>JVMVersion</key>
		<string>1.4+</string>
		<key>MainClass</key>
		<string>EchoAppPackage</string>
		<key>Properties</key>
		<dict>
			<key>apppkg</key>
			<string>$APP_PACKAGE</string>
			<key>javaroot</key>
			<string>$JAVAROOT</string>
		</dict>
	</dict>

and the java...

public class EchoAppPackage {

	public static void main(String[] args) {
		System.out.println("$APP_PACKAGE = " + System.getProperty("apppkg"));
		System.out.println("$JAVA_ROOT = " + System.getProperty("javaroot"));
		System.out.println("user.dir = " + System.getProperty("user.dir"));
	}
	
}

compiled and the class file place put into the $JAVAROOT classpath location. The app run from my home directory gives...

$APP_PACKAGE = /Users/mjh/EchoApp.app
$JAVA_ROOT = /Users/mjh/EchoApp.app/Contents/Resources/Java
user.dir = /Users/mjh

I think the advantage to you of using the Info.plist properties over the normal java user.dir property is if the user decides for some twisted reason to rename your application. user.dir will not show that, the Info.plist properties will.

But I think that shows most of your options from a java application bundle.
