In this tutorial, we will show you how to install Java in SUSE or OpenSUSE Environments. In this tutorial, we are using our virtual machine OpenSUSE.
This is my testing system:
cat /etc/os-release
NAME=openSUSE VERSION="42.1 Milestone 1 (Malachite)" VERSION_ID="42.1milestone1" PRETTY_NAME="openSUSE Leap 42.1 Milestone 1 (Malachite) (x86_64)" ID=opensuse ANSI_COLOR="0;32" CPE_NAME="cpe:/o:opensuse:opensuse:42.1" BUG_REPORT_URL="https://bugs.opensuse.org" HOME_URL="https://opensuse.org/" ID_LIKE="suse"
First Download the file from the oracle website.
Download the rpm installer jre-8u51-linux-x64.rpm from the oracle java site at:
Start Install Java
rpm -ivh jre-8u51-linux-x64.rpm
error: Failed dependencies: /usr/sbin/alternatives is needed by jre1.8.0_51-1.8.0_51-fcs.x86_64
Solve it with: Make symbolic link to /usr/sbin/alternatives:
ln -s /usr/sbin/update-alternatives /usr/sbin/alternatives
Install without dependencies:
rpm -ivh --nodeps jre-8u51-linux-x64.rpm

Start Java configuration:
Run as root:
alternatives --install "/usr/bin/java" "java" "/usr/java/jre1.7.0_40/bin/java" 1
update-alternatives --set java /usr/java/jre1.8.0_51/bin/java

update-alternatives --set javaplugin /usr/java/jre1.8.0_51/lib/amd64/libnpjp2.so
Now check with root user:
<span style="color: #ff0000;">update-alternatives --list java</span>
/usr/java/jre1.8.0_51/bin/java
/usr/lib64/jvm/jre-1.8.0-openjdk/bin/java
update-alternatives --list javaplugin
/usr/java/jre1.8.0_51/lib/amd64/libnpjp2.so
update-alternatives --config java
There are 2 choices for the alternative java (providing /usr/bin/java).
Selection Path Priority Status

2 /usr/lib64/jvm/jre-1.8.0-openjdk/bin/java 1805 manual mode
Press enter to keep the current choice[*], or type selection number:

For 32bit version:
update-alternatives --install "/usr/bin/java" "java" "/usr/java/jre1.8.0_51/bin/java" 1 update-alternatives --set java /usr/java/jre1.8.0_51/bin/java update-alternatives --install "/usr/lib/browser-plugins/javaplugin.so" "javaplugin" "/usr/java/jre1.8.0_51/lib/i386/libnpjp2.so" 1 update-alternatives --set javaplugin /usr/java/jre1.8.0_51/lib/i386/libnpjp2.so
Verify the Java version:
Run the following commands as root user.
inux-0xn4:/home/mohamed/Downloads # java -version java version "1.8.0_51" Java(TM) SE Runtime Environment (build 1.8.0_51-b16) Java HotSpot(TM) 64-Bit Server VM (build 25.51-b03, mixed mode)
Test java plugin installed:
Please check your plugin on https://www.java.com/verify
Done!
