Installing Java 8 on Ubuntu

No Comments

Quick notes about installing Java 8 on Ubuntu 12.4 LTS. Option 2 is almost same for RHEL 7.1.

Option 1:

sudo add-apt-repository ppa:webupd8team/java
sudo apt-get update
sudo apt-get install oracle-java8-installer

This unfortunately did not install the latest from Java for me so I moved to option 2 in may case but if it works for you, it is very easy to use that package and update.

Option 2: Manually

Download package from Oracle-Java site and extract it with tar. Then;

sudo mv jdk1.8.0_72 /usr/lib/jvm/

sudo update-alternatives –install "/usr/bin/java" "java" "/usr/lib/jvm/jdk1.8.0_72/jre/bin/java" 1
sudo update-alternatives –set java /usr/lib/jvm/jdk1.8.0_72/jre/bin/java

Firefox:

sudo update-alternatives –install /usr/lib/mozilla/plugins/mozilla-javaplugin.so mozilla-javaplugin.so /usr/lib/jvm/jdk1.8.0_72/jre/lib/amd64/libnpjp2.so 1
sudo update-alternatives –config mozilla-javaplugin.so

And if needed;

sudo update-alternatives –install "/usr/bin/javac" "javac" "/usr/lib/jvm/jdk1.8.0_72/bin/javac" 1
sudo update-alternatives –install "/usr/bin/javaws" "javaws" "/usr/lib/jvm/jdk1.8.0_72/jre/bin/javaws" 1

To choose versions;

sudo update-alternatives –config java
sudo update-alternatives –config javac
sudo update-alternatives –config javaws

Good luck.
