This article is about installing Oracle Java on openSUSE.

[edit] Situation
Because of licensing issues, Oracle (Sun) Java JRE cannot be included in the repositories of openSUSE anymore. Here is a quick guide on how to install the newest and secure version. On the Oracle Java website two versions are available for downloading:
- Java Runtime Environment (JRE): includes Java virtual machine), libraries, Java application launcher, web browser and in general everything should be needed to run programs written with Java language.
- Java Development Kit (JDK): in addition to the Java Runtime Environment (JRE) above, in includes all the tools needed to develop, test and debug programs written with Java language.
Being the installation of JRE a shorter version of JDK installation, the procedure to install the JDK will be shown first, this way differences with JRE installation should be clearer, should someone want to install just the Java Runtime Environment, for some reason. Therefore, installing both the packages when they have the same version number, it is not (quite) useful.
With both the procedures given below, for JDK and for JRE installation, the same name, i.e. jdk_Oracle, will be used for the symbolic link pointing to the folder where the Oracle Java Environment is located, by the way. This way, one might even follows both the procedures in a sequence, since the JDK and the JRE are installed in different directories, but only the latter is going to be used by your system (or whichever the symbolic link is pointing to).
[edit] Procedure with development environment included (JDK)
Full Java Environment included.
Warning From here to the end of this section, for any sub-section (#Updating Oracle Java included), if your system has a 64-bit architecture, any occurrence of /usr/lib must be replaced with /usr/lib64, when you are going to type the commands below.
[edit] Install Oracle Java SE
- Download Oracle Java SE Development Kit (JDK) from the Oracle Java website. Save it to an easy to remember directory (eg. /tmp)
Download a suitable version for your system architecture. E.g.: with Oracle Java version 1.7.0_7:
- Linux x86 (32-bit architecture)
- jdk-7u7-linux-i586.tar.gz
- Linux x64 (64-bit architecture)
- jdk-7u7-linux-x64.tar.gz
- Open a terminal and run:
cd /path/to/downloaded/java
- Decompress it with (as root, just to be sure):
sudo tar -xzf ./jdk-7uX-linux-XX.tar.gz
- Fix permissions for the expanded directory and its content:
sudo chown -R root:root jdk1.X.X_XX/
- Open JDK is installed by default in /usr/lib, so let's move Oracle Java to /usr/lib as well:
sudo mv ./jdk1.X.X_XX/ /usr/lib/
- Create a symbolic link to /usr/lib/jdk1.X.X_XX/ (this will be important later for updating)
sudo ln -s -T /usr/lib/jdk1.X.X_XX/ /usr/lib/jdk_Oracle
[edit] Inform the system
Java application launcher

[edit] Setting options specific for version of installed Java (option)
You can even set Oracle Java as an alternative for JDK (and JRE) environments, just for a particular version of Java, in this case 1.7.0; the changes will be applied with usual update-alternatives.
Java application launcher

To select your alternative:
sudo /usr/sbin/update-alternatives --config java_sdk_1.7.0
[edit] Updating Oracle Java
Updating Oracle Java is really easy thanks to the /usr/lib/jdk_Oracle link that was created above.
- Repeat the procedure up to moving the jdk1.X.X_XX to /usr/lib
- Then just change the symbolic link /usr/lib/jdk_Oracle to point to the new Java SE sudo ln -s -f -T /usr/lib/jdk1.X.Y_YY/ /usr/lib/jdk_Oracle
- Finally re-compress man files as described above.
[edit] Adding Java Control Panel
Once you set Oracle Java as your default jvm, you might want to be able to run /usr/lib/jdk_Oracle/bin/jcontrol (replace lib with lib64 if you are running a 64-bit system), e.g. the application providing your Java Control Panel, directly from the applications menu for your favourite Desktop Environment.
In order to add item "Java - Java Control Panel" to the application menu, you will need to create a couple of symbolic links, which you could delete with sudo rm /path/to/your/symlink, should you want to remove Oracle Java. You can create those symbolic links using following commands, taking care that /usr/lib must be replaced with /usr/lib64 if you own a 64-bit system:
sudo ln -s /usr/lib/jdk_Oracle/jre/bin/jcontrol /usr/bin/
sudo ln -s /usr/lib/jdk_Oracle/jre/lib/desktop/icons/hicolor/16x16/apps/sun-jcontrol.png /usr/share/icons/hicolor/16x16/apps/
sudo ln -s /usr/lib/jdk_Oracle/jre/lib/desktop/icons/hicolor/48x48/apps/sun-jcontrol.png /usr/share/icons/hicolor/48x48/apps/

[edit] Procedure with runtime environment only (JRE)
For Java Runtime Environment only.
Warning From here to the end of this section, for any sub-section (#Updating Oracle Java (JRE) included), if your system has a 64-bit architecture, any occurrence of /usr/lib must be replaced with /usr/lib64, when you are going to type the commands below.
[edit] Install Oracle Java SE (JRE)
- Download Oracle Java SE Runtime Environment (JRE) from the Oracle Java website. Save it to an easy to remember directory (eg. /tmp)
Download a suitable version for your system architecture. E.g.: with Oracle Java version 1.7.0_7:
- Linux x86 (32-bit architecture)
- jre-7u7-linux-i586.tar.gz
- Linux x64 (64-bit architecture)
- jre-7u7-linux-x64.tar.gz
- Open a terminal and run:
cd /path/to/downloaded/java
- Decompress it with (as root, just to be sure):
sudo tar -xzf ./jre-7uX-linux-XX.tar.gz
- Fix permissions for the expanded directory and its content:
sudo chown -R root:root jre1.X.X_XX/
- Open JDK is installed by default in /usr/lib, so let's move Oracle Java to /usr/lib as well:
sudo mv ./jre1.X.X_XX/ /usr/lib/
- Create a symbolic link to /usr/lib/jdk1.X.X_XX/ (this will be important later for updating)
sudo ln -s -T /usr/lib/jre1.X.X_XX/ /usr/lib/jdk_Oracle
[edit] Inform the system (JRE)
