Article Flexible installations with IzPack in Java Magazin 07.08

I published an article about flexible installations with IzPack 3.11 in the current issue (07.08) of Java Magazin. Full quellcode for a sample project is included.

How to debug variables and conditions in IzPack

From IzPack 3.11 on, there's a built-in debugger for variables and conditions. The debugger is activated when the installer is called with -DTRACE=true as JVM option.

Ex.1:

java -DTRACE=true -jar myInstaller.jar

The debugger shows up as a panel in the east of the InstallerFrame or if the guiModifier showDebugWindow is set to true, it will show up as seperate window.

Ex.2:

<modifier value="true" key="showDebugWindow">

IzPack now has built-in conditions

IzPack now has built-in conditions which means, that there are some predefined conditions which can be used in the installer. These conditions are:

• izpack.windowsinstall


• izpack.linuxinstall


• izpack.solarisinstall


• izpack.macinstall

There's also a PackSelectionCondition for every pack. The Ids for these condition will be built up from the pack id or if not specified, the pack name. If there's a pack called Testpack with id test.pack, there will be a condition called izpack.selected.test.pack
