First of all I want to thanks Klaus again for all the effor he is putting in
helping me.
I've been trying with a non-blank path and nothing differnt happened. Still
I removed the blank in standalone-compiler.jar (I think was caused for
cut/paste into web broswer.)
So the code looks now this way
<?xml version="1.0" encoding="UTF-8"?>
<project name="Installer Generator" default="default" basedir=".">
<target name="default" description="Main target">
<izpack input="/Users/jacobo/Desktop/export/tmp/installer.xml"
output="/Users/jacobo/Desktop/acobo-installer.jar"
basedir="/Users/jacobo/Desktop/export/tmp"
izpackdir="/Users/jacobo/Documents/workspace/EIG/" />
</target>
</project>
Same nullpointer exception at same place.
I don't know how to debug this, even further I don't know how to compile
izpack by myself.
