[computer-go] java setup (slightly off topic :)

[<postneo@xxxxxxxxxxxxxxx>]

While not strictly a go problem ....
can anyone tell me how to setup the java environment so that I can run
kgsGtp as a robot ??
I dont know ANYTHING about java (perl dude), but I cant even get the first
prog to run, so I cant start learning it.

I have gnugo installed, jre and jsdk, gnugo runs fine in text mode but I
cannot get kgsGtp to go (no pun)

(On RH 7.3, dual cpu machine)
steps taken so far ...
download and install selfextracting rpm binaries from Sun, install rpms for
jre and sdk
versions j2sdk1.4.2_06 for both sdk and sre installed in

/usr/java/j2sdk1.4.2_06
and
/usr/java/j2re1.4.2_06

added ENV variables to /etc/bashrc as follows

PATH=/usr/java/j2sdk1.4.2_06/bin:/usr/java/j2re1.4.2_06/bin:$PATH:$HOME/bin:
./
export PATH
export JAVA_HOME=/usr/java/j2sdk1.4.2_06
export
CLASSPATH=/usr/java/j2sdk1.4.2_06/lib/tools.jar:/usr/java/j2sdk1.4.0_03/jre/
lib/rt.jar:./

when running the application it complains that it cant load a java virtual
machine. The java_vm binary is in
/usr/java/j2re1.4.2_06/bin/
but even adding this to the path does not help

[agray@hal java]$ java -jar kgsGtp.jar /etc/KGSgtp.conf
Exception in thread "main" java.lang.UnsupportedClassVersionError:

        at java.lang.ClassLoader.loadClass(Unknown Source)
        at java.lang.ClassLoader.loadClassInternal(Unknown Source)

Anyone got any ideas what else I need to do ?? Have tried various
combinations of the PATH without success.
