Oracle Java Installer

Oracle java (jdk/jre) installler script for linux. It simplifies the installation of Oracle java from a downloaded source (tar.gz). It also maintains consistency among multiple versions of java (jdk/jre). Uninstalling any java version installed with this script will fall back to the next most recently installed version of java.

Install oraji:

Give the install.sh file execution permission and run it in terminal (with root privilege).

sudo ./install.sh
On Ubuntu:

sudo add-apt-repository -y ppa:neurobin/ppa
sudo apt-get update
sudo apt-get install oraji

Java Installation Instruction:

Run in terminal:

sudo oraji '/path/to/the/jdk_or_jre_archive'
(or run sudo /path/to/oraji /path/to/the/jdk_or_jre_archive after giving the oraji script execution permission if you didn't install the script).

That's it. Now if you want to populate JAVA_HOME and other environment variables run source /etc/profile or logout and login.

Java Uninstallation Instruction:

  1. Run oraji -u (or path/to/oraji -u if you didn't install the oraji script).
  2. Choose the version to be uninstalled from the list.
  3. The version can be provided as command line argument too i.e oraji -u version (or /path/to/oraji -u version if you didn't install the script).

Note:

  1. The java version points to the jdk/jre install directory: /usr/lib/jvm/jdk|jre<version_number> and comprises with both the jdk/jre part and the version_number part.
  2. You shouldn't run oraji -u version (with a version argument) unless you are sure of it. Simply run oraji -u and let oraji detect the version for you.
  3. After uninstalling with this script, if Java falls back to another Java version then JAVA_HOME and other environment variables will be updated accordingly (you will need to run source /etc/profile manually to populate them immediately), mozilla plugin will be restored to the fallback java.

N.B: The uninstallation method is only for the oracle java installed with the oraji script. It deletes the /usr/lib/jvm/jdk|jre<version_number> directory and all exports and environment variables that was included in /etc/profile by oraji and the mozilla plugin. If a fall back java is available, exports and environment variables will be available for this java version and mozilla plugin will be restored.

Manage multiple Java versions:

Switching between Java versions was never easier

You can install multiple Java versions and set whichever version you want as your current Java.

  1. To check which version of Java is currently active (with all other available Java versions) run oraji -c
  2. To activate a Java version, run sudo oraji -s and select the version from the list.

Options:

Option Alt. Option Details
-v --version Show version
-h --help Show help
-i --install Install from an archive path
-u --uninstall Uninstall java
-s --set Set a java version
-c --check Show the installed java versions
