Q: How can I execute the a package installer on Mac OSX from IzPack?

A: You can include a shell script with your IzPack installer that mounts a dmg, then launches the installer within it. The shell script looks something like this:

No Format

#!/bin/sh
hdiutil mount $INSTALL_PATH/yourpackage.dmg
open /Volumes/yourpackage/YourPackageInstaller.mpkg/

To execute the shell script from within a <pack> in your install.xml file, use the following lines:

No Format

<pack name="yourpackage" os="mac">
  <parsable targetfile="$INSTALL_PATH/loaddmg.sh"/>
  <file targetdir="$INSTALL_PATH/" src="yourpackage.dmg"       os="mac" unpack="false"/>
  <executable type="bin" stage="never" targetfile="$INSTALL_PATH/loaddmg.sh" os="mac" />
  <executable type="bin" stage="postinstall" targetfile="$INSTALL_PATH/loaddmg.sh" os="mac" />
</pack>

Q: How can I get more debug output from an installer?
A: You can execute the installer with the following command to get a full debug stream from IzPack:

No Format

java -jar -DTRACE=TRUE yourinstaller.jar

Q: How can I debug an uninstaller as it launches itself several times to remove file locks and hence we get no console output?
