Introduction

OS/specific operations can be done from IzPack by

• launching shell scripts or executables
• JNI over shared libraries.

There are specific considerations which appear as subpages of this page.

Launching Native Scripts Or Executables

To launch external scripts or binaries, zou can use the following built/in facilities:

• Process Panel
• Dynamic Variables

Using Native JNI Libraries

Accessing shared libraries on the target operating system is done by JNI access in mapper libraries compiled for the dedicated OS.

Those shared libraries must be explicitely included in an installer, see Native Libraries - <native>.

Several built-in facilities make usage of native libraries:

• RegistryInstallerListener / RegistryUninstallerListener
  COIOSHelper*.DLL for registry access.
• CheckedHelloPanel
  COIOSHelper*.DLL for registry access.
• ShortcutPanel
  ShellLink*.DLL for acessing the Windows API.
• <blockable> files in filesets, files / single files.
  SetupAPI*.DLL for accessing the Windows Setup API.
