Ubuntu with Oracle/SUN JRE/JDK

December 17th, 2010 No comments

In the current Ubuntu one can only get the open-jre and open-jdk installed via apt(itude). Because of some major issues concerning Swing, I needed to install the sun-jre and sun-jdk. To make this possible you have to edit /etc/apt/sources.list as root (or with sudo 😉 ). Uncomment the two following lines close to the end of the file.

deb http://archive.canonical.com/ubuntu lucid partner
deb-src http://archive.canonical.com/ubuntu lucid partner

Save the file and do a

sudo aptitude update

or

sudo apt-get update

After that you can install the packages sun-java6-jre and sun-java6-jdk with an aptitude search (or apt-cache search) ready for installation. For using this runtime environment as systems default you need to do a

sudo update-alternatives --config java

which produces output similar to the following(sorry for the german bash 😉 )

Es gibt 2 Auswahlmöglichkeiten für die Alternative java (welche /usr/bin/java bereitstellen).

Auswahl      Pfad                                      Priorität Status
------------------------------------------------------------
* 0          /usr/lib/jvm/java-6-openjdk/jre/bin/java   1061      Auto-Modus
1            /usr/lib/jvm/java-6-openjdk/jre/bin/java   1061      manueller Modus
2            /usr/lib/jvm/java-6-sun/jre/bin/java       63        manueller Modus

Drücken Sie die Eingabetaste, um die aktuelle Wahl[*] beizubehalten,
oder geben Sie die Auswahlnummer ein:

choose the correct number (here: 2), hit Enter…done!

The book all of us have been waiting for has finally arrived: HPC for Dummies

Available as a free download (registration required, though) at

My first reading experiences: it’s about clusters, not HPC.
