Right. The 1.4 JRE is being used within Mozilla. I'm sure Russel
wants to use the 1.5 JRE instead, but that doesn't address the
original problem. The 1.4 JVM should be fine, and doesn't explain the
NullPointerException received during the tutorial. That's a
legitimate bug in the tutorial applet (what is the URL to that applet?
I could take a look).
Anywho, Alex is right about what needs to be done to replace the 1.4
JRE plugin with the 1.5 JRE plugin. You should be able to execute the
following as root and you'll be in ship shape:
rm -rf libjava*
ln -s /usr/java/jdk1.5.0_04/jre/plugin/i386/ns7/libjavaplugin_oji.so
Browse to http://www.javaranch.com/game/game2.jsp
Make sure you see the cows walking around.
