Class Installer

  • public class Installer
extends Object
    Really simple installer. This basically just copies stuff that has been set up in the create_installer.sh script, so chances are excellent if you need to change the installer, you should be looking there.

    This gets copied to your jar and will just copy everything in the jar to a given directory (including sub directories). So make the tree you want, jar it up with this class and run it.

    Caveat for changing this class

    This is a completely standalone class -- no dependencies but plain Old Java -- because otherwise you have to manage dependencies (might involve writing your own class loader!) for this installer program which can get very hard. The idea is that this is a lean, single class. Even inheritance doesn't work.
