Installing JAVA on Ubuntu 14.04

To run Alfresco on your Ubuntu server you will need Java. The installer will add this for you but you can install it yourself. This ensures you have the latest version.


based on this web page

I use a combination of FileZilla and PuTTY

Get the latest JDK from the Oracle website


Upload it to a directory on your server

eg /tmp/

Make a directory for your Java installation

mkdir /opt/java

Go to the tmp directory and untar the file

tar -zxf JDK_TAR_FILE -C /opt/jdk

Replace caps above with the name of the JDK file you have downloaded

You will then have a folder with the name of the JDK version, eg  jdk1.8.0_25

Set default JVM

update-alternatives –install /usr/bin/java java /opt/jdk/JDK_VERSION/bin/java 100


update-alternatives –install /usr/bin/javac javac /opt/jdk/JDK_VERSION/bin/javac 100



update-alternatives –display java


update-alternatives –display javac
