Running Java under Ubuntu
In order to run Java programs and Java applets, you must have a Java environment installed. The GCJ flavor of Java is installed as default, and is usually fine for most purposes. You may, however, have a need to run the Sun flavor of Java if something does not work correctly.
To get Sun Java under Ubuntu 7.04 or later running on Intel or PowerPC platform, you should enable the Universe repository in Add/Remove programs, and install the openjdk-6-jre package. (Note: PowerPC version is slow).
To get Sun Java under Ubuntu 6.06 or 6.10 running on Intel x86 platform, you should enable the Universe repository in Add/Remove programs, and install the sun-java5-bin package.
(Note: I do not know the corresponding command for Kubuntu, but you can always install a package with sudo apt-get install thepackage in a Terminal. Please update if you know better)
See JavaInstallation for details about installation of other flavors of Java.
Choosing the default Java to use
Just installing new Java flavours does not change the default Java pointed to by /usr/bin/java. You must explicitly set this:
- Open a Terminal window
Run sudo update-java-alternatives -l to see the current configuration and possibilities.
Run sudo update-java-alternatives -s XXXX to set the XXX java version as default. For Sun Java 6 this would be sudo update-java-alternatives -s java-6-sun
Run java -version to ensure that the correct version is being called.
