[ubuntu] Installing java? [12.10]

This tutorial will show how to install sun java 6 jre for those having problem installing it on Ubuntu 12.04. OAB-Java is a project hosted on github.com that create a local ‘apt’ repository for Sun Java 6 and/or Oracle Java 7 packages.

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.

I'd like to install Eclipse on Ubuntu for Java development.

Hello, the default java installation is openJDK.

/usr/bin/java -> /etc/alternatives/java /etc/alternatives/java -> /usr/lib/jvm/jre-1.7.0-openjdk.x86_64/bin/java

I want to install JDK 1.6, and executed this command:

Code: alternatives --install /usr/bin/java java /usr/lib/java/jdk1.6.0_45/bin/java 20000 But the symbolic link does change at all. What might be wrong?

Hey all!
