I don't want to do an extended search. That's not so important. I would
just look in C:\Programme\Java, C:\Program Files\Java since that is the
default installation location Sun's windows installer recommends, if I
recall correctly (at least in all my jre 1.5 versions and my app needs a
jre 1.5). I was just wondering, why the JRE was not detected by the
search field although I copied the code from the documentation.

Yes, that's definetly more important than a successful automatic search.
Frankly, I haven't been aware of the existence of a PathInputPanel until
now. So, I'll have a look at that and take a closer look at the
documentation. BTW, where can I find a more recent version since the one
mentioned on http://www.izforge.com/izpack/downloads is marked as outdated?

Anyway, thanks for the hints.
