I want to play this java simulation: http://www.compadre.org/OSP/items/detail.cfm?ID=9640 in java 3d mode on a linux (ubuntu) system. But it doesn't work.
If I switch to java 3d-mode it complains that java 3d is not installed.
sudo aptitude install libjava3d-java didn't help.
Then I did a right click in this java app and selected Diagnostics-> About Java 3D. Then I get the message:
Java 3D was not found in: /usr/lib/jvm/java-6-openjdk-i386/jre/lib/ext:/usr/java/packages/lib/ext
Then I tried
cp /usr/share/java/*3d* \
but I get the same error message again.
I start the java app like this:
java -jar ejs_astronomy_SolarLunarEclipse.jar
I tried this on two systems, one freshly installed and also switched from openjdk to sun-jdk temporarily without any effect.
Any idea how I can get this work?
