I use an application regularly that relies on Java. Their support department insists you update to the latest and greatest version from Sun (will NOT help w/ support issues unless you are using newest Sun sanctioned version). I’m using Kubuntu, and have noticed that it is usually 1-2 versions behind (e.g. today I’m running 1.6.0-26, that is the most up-to-date version available through Apt. When I go to the Java website, it verifies I’m running 1.6.0-26, and says an update is available (0-27!))
Is there a way to install a newer/different version of Java from Sun w/o using Apt? Can I download a tarball and configure Kubuntu to use the newer downloaded version vs. the officially sanctioned version provided through Apt?
Thanks for the help (this has been a nagging problem since v. 0-15)

How to set JAVA_HOME variable in Ubuntu:-

‘sudo’ open up /etc/bash.bashrc and add the following to the end of the file. (NOTE: Set the java path to whatever the actual path is on your environment if it does not match /usr/lib/jvm/java)

JAVA_HOME=/usr/lib/jvm/java
export JAVA_HOME
PATH=$PATH:$JAVA_HOME/bin
export PATH

you must reboot, try running the following:

$ echo $JAVA_HOME
/usr/lib/jvm/java
echo $PATH
[probably lots of paths]:/usr/lib/jvm/java/bin

This is how problem is solved.

Hello friends,
i also want to install JDK 1.6 to run my Netbeans IDE,but I encountererd the following error,when i type sudo apt-get install sun-java6-jdk :

Package sun-java6-jdk is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
E: Package sun-java6-jdk has no installation candidate

I’m configuring my JDK1.6.0_23 on Ubuntu 10.04 as follows…

Edit profile file:
sudo nano ~/.profile

add these lines:
export JAVA_HOME=/usr/lib/jvm/jdk1.6.0_23
export PATH=$JAVA_HOME/bin:$PATH

Apply profile changes:
. .profile

Check JAVA_HOME environment variable:
echo $JAVA_HOME
OUTPUT:
/usr/lib/jvm/jdk1.6.0_23

Configure alternatives for java, javac, jar
sudo update-alternatives –install /usr/bin/java java /usr/lib/jvm/jdk1.6.0_23/bin/java 100
sudo update-alternatives –install /usr/bin/javac javac /usr/lib/jvm/jdk1.6.0_23/bin/javac 100
sudo update-alternatives –install /usr/bin/jar jar /usr/lib/jvm/jdk1.6.0_23/bin/jar 100

Check java, javac version:
java -version

OUTPUT:
java version “1.6.0_23″
Java(TM) SE Runtime Environment (build 1.6.0_23-b05)
Java HotSpot(TM) Server VM (build 19.0-b09, mixed mode)

javac -version

OUTPUT:
javac 1.6.0_23

Most of this worked for me but I got stuck when setting the path variables, what you actually have to do it run these two lines in the terminal:

export JAVA_HOME=/usr/java export PATH=$PATH:$JAVA_HOME/bin

Obviously change “/usr/java” to wherever java is installed.
