Install Oracle Java 8 on Manjaro 16.10

This tutorial will guide you through the installation of Oracle Java 8 Runtime Environment (JRE) on Manjaro 16.10 Linux. Java is an essential software or package needed by many software/applications. I am using Manjaro Xfce edition and by default, it already shipped with OpenJDK Runtime Environment. You may check your Manjaro with this command to see if Java is installed already.

java -version

Steps to install Oracle Java 8 on Manjaro

Step 1. Download Oracle Java 8

Download the Oracle Java 8 package from the official website. Alternatively, you can simply copy and paste the following command on Terminal to download the Oracle Java 8 package.

wget http://javadl.oracle.com/webapps/download/AutoDL?BundleId=216424 -o java-latest

For 32 bit system, use this one

wget http://javadl.oracle.com/webapps/download/AutoDL?BundleId=216422 -o java-latest

Step 2. Extract the package

Use this command to extract the package

tar -zxvf java-latest

Step 3. Move/Copy the package to /opt

Now copy or move the extracted directory to /opt.

sudo cp -R jre1.8.0_111 /opt/

Example:

Step 4. Create Symlink

If you have OpenJDK Java installed, we need to move existing java binary first. Use this command below to move the existing OpenJDK java.

sudo mv /usr/bin/java /usr/bin/java_backup

Now we can create symlink to our Oracle Java

sudo ln -s /opt/jre1.8.0_111/bin/java /usr/bin/java

Now check Java version once again and now you should see something like this

Optionally, we need to configure Firefox to use this new Java version.

mkdir ~/.mozilla/plugins/
ln -s /opt/jre1.8.0_111/lib/amd64/libnpjp2.so ~/.mozilla/plugins/libnpjp2.so

Now close any running Firefox session and open it again. Type "about:plugins" on the address bar. You should see Oracle Java listed there.
