[izpack-users] Getting value of env variable

[Hans Aikema]

Wiktor,

As JAVA_HOME is supposed to be used to determine where your Java 
Installation directory resides I'm fairly sure that you should not have 
an application installation which writes files to that location UNLESS 
you're installing a Java runtime environment (in which case your 
installation folder should be the JAVA_HOME). So you might want to 
reconsider trying to do this since you're putting your application files 
in a directory which is meant to only contain your Java Runtime environment.

However, you can use environment variables in your installer. Refer to 
the Izpack documentation installed with Izpack 
(doc/izpack/xhtml/index.html in your Izpack installation folder).

regards,
Hans Aikema
