1.7 on a PPC box

[Drechsel Wolf]

Hi everybody,

I installed

http://landonf.bikemonkey.org/static/soylatte/bsd-dist/openjdk7_darwin/openjdk7-macppc-2009-12-16-b4.tar.bz2

on my Mac OS X 10.5.8 Leopard, PPC G4.

I adjusted  PATH and JAVA_HOME, and

'$ java -version' delivers

$ java -version
openjdk version "1.7.0-internal"
OpenJDK Runtime Environment (build
1.7.0-internal-landonf_2009_12_16_12_54-b00)
OpenJDK Zero VM (build 17.0-b05, interpreted mode)

So the installation seems to have gone right.

But when I open Utilities/Java-Settings.app, only the outdated 1.4.x  
und 1.5.x java versions are displayed; if I launch a more recent java  
app, that one states that only java 1.5.x is installed.

What can I do to notify the system that there is java 1.7 installed?

Thanks and greetings,

Wolf
