This article is about installing Oracle Java on openSUSE.

[edit] Situation

Due to Oracle (Sun) licensing policies, 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, it includes all the tools needed to develop, test and debug programs written with Java language.

The JRE installation is a shorter version of the JDK installation, therefor 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 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. This way, one might even follow both 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] Java Runtime Environment Install using Oracle's RPM

The purpose of this installation method is to be a quick and easy setup. You will not have the Icedtea Web plugin, only the official Java. This method is recommended for those that require Oracle's Java for websites that insist on the genuine article in order to be accessed.

Determine what architecture you are running before downloading the package to your system. To be certain of your architecture, open a terminal by running the command (Alt+F2 in KDE): konsole or xterm

Execute the command:

uname -m

If the output is:

i486
i586
i686

You have a 32-bit architecture

If the output is:

x86_64

You have a 64-bit architecture

Download the official RPM from Java.com and install the RPM with whatever method you prefer. In most cases, navigating to the RPM in the file manager and clicking on it will install it. Or you can install via the terminal, e.g. run the command (Alt+F2 in KDE): konsole or xterm to open a terminal then type:

su

Enter your root password, this will put you in "Superuser" mode. Navigate to the location of the download, Firefox or Chrome will typically put it in ~/Downloads

cd ~/Downloads

To install using terminal type:

rpm -ivh jre-7u45-linux-i586.rpm

or, if you downloaded the 64-bit RPM:

rpm -ivh jre-7u45-linux-x64.rpm

Once the install is complete, copy and paste the following into terminal as root:

zypper rm icedtea-web
update-alternatives --install "/usr/bin/java" "java" "/usr/java/latest/bin/java" 1
update-alternatives --set java /usr/java/latest/bin/java

For 32-bit architecture:

ln -s /usr/java/latest/lib/i386/libnpjp2.so /usr/lib/browser-plugins/

For 64-bit architecture:

ln -s /usr/java/latest/jre/lib/amd64/libnpjp2.so /usr/lib64/browser-plugins/

The installation of Java and appropriate links are complete. You can now use Java in any web browser on your system.

[edit] Limit Java Disk Usage

Although no icon appears in the menu, there is a Java Control Panel that allows you to easily adjust many settings. In order to access it, open a terminal or in KDE press Alt+F2 to run a command and enter:

jcontrol

• Click Settings... under Temporary Internet Files
• Under Disk Space adjust the amount of disk space for storing temporary files to your choosing. 50 to 100 MB should be sufficient.
• Click OK to close the dialog box and OK to close the Java Control Panel

[edit] Procedure with development environment included (JDK)

Full Java Environment included.

[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)

• 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/

Linux x86 (32-bit architecture)

• 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

Linux x86_64 (64-bit architecture)

• Open JDK is installed by default in /usr/lib64, so let's move Oracle Java to /usr/lib64 as well:
  sudo mv ./jdk1.X.X_XX/ /usr/lib64/
• Create a symbolic link to /usr/lib64/jdk1.X.X_XX/ (this will be important later for updating):
  sudo ln -s -T /usr/lib64/jdk1.X.X_XX/ /usr/lib64/jdk_Oracle

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.

[edit] Updating Oracle Java

Updating Oracle Java is really easy thanks to the /usr/lib/jdk_Oracle (/usr/lib64/jdk_Oracle on x86_64) link that was created above.

Linux x86 (32-bit architecture)

1) Repeat the procedure up to moving the jdk1.X.X_XX to /usr/lib

Linux x86_64 (64-bit architecture)

1) Repeat the procedure up to moving the jdk1.X.X_XX to /usr/lib64

3) Finally re-compress the man files as described above (all architectures).

[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 favorite 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:

[edit] Making Oracle Java default (JRE)

You will have to select the appropriate number after running: (This also can be used to switch between different implementations of java).

[edit] Setting options specific for version of installed Java JRE (option)

You can even set Oracle Java as an alternative for the JRE environment, just for a particular version of Java, in this case 1.7.0; the changes will be applied with usual update-alternatives.

[edit] Updating Oracle Java (JRE)

Updating Oracle Java is really easy thanks to the /usr/lib/jdk_Oracle (/usr/lib64/jdk_Oracle on x86_64) link that was created above.

Linux x86 (32-bit architecture)

1) Repeat the procedure up to moving the jre1.X.X_XX to /usr/lib

Linux x86_64 (64-bit architecture)

1) Repeat the procedure up to moving the jre1.X.X_XX to /usr/lib64

3) Finally re-compress the man files as described above (all architectures).

[edit] Adding Java Control Panel (JRE)

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:
