System Requirements
See Oracle JDK 7 and JRE 7 Certified Systems Configurations for information about supported platforms, operating systems, andbrowsers.
On a 64-bit system, you can download either the 64-bit or the 32-bit version of the Java platform. However, if you are using a 32-bit browser and you want to use the plugin, then you need to install the 32-bit version of the Java platform. To determine which version of Firefox you are running, launch the application, and select the menu item Help -> About Mozilla Firefox. At the bottom ofthe window is a version string line that contains either "Linux i686" (32-bit) or "Linux x86_64" (64-bit). To setup the Java plugin, see Manual Installation and Registration of Java Plugin for Linux.
JRE 7 Installation Instructions
Note: For any text on this page containing the following notation, you must substitute the appropriate JRE update version number for the notation.<version>
For example, if you are installing update JRE 7 update release 1, the following string representing the name of the bundle:
jre-7u<version>-linux-i586.sh
would become:
jre-7u1-linux-i586.sh
Note that, as in the preceding example, the <version> number is sometimes preceded with the letter u, for example, 7u2, and sometimes itis preceded with an underbar, for example, jre1.7.0_02.
The following table lists the options available for downloading the JRE 7 release on a Linux platform. The link in the first column takes you to the instructions for that version.
Download File | Architecture | Who Can Install |
jre-7u<version>-linux-x64.tar.gz | 64-bit | anyone |
jre-7u<version>-linux-i586.tar.gz | 32-bit| anyone |
jre-7u<version>-linux-x64.rpm | 64-bit RPM-based Linux | root |
jre-7u<version>-linux-i586.rpm | 32-bit RPM-based Linux | root |

Installation of the 64-bit JRE on Linux Platforms
This procedure installs the Java Runtime Environment (JRE) for 64-bit Linux, using an archive binary file (.tar.gz).
These instructions use the following file:jre-7u<version>-linux-x64.tar.gz
1. Download the file. Before the file can be downloaded, you must accept the license agreement. The archive binary can be installed by anyone (not only root users), in any location that you can write to. However, only the root user can install the JRE into the system location.
2. Change directory to the location where you would like the JRE to be installed. Movethe .tar.gz archive binary to the current directory.
3. Unpack the tarball and install the JRE.
% tar zxvf jre-7u<version>-linux-x64.tar.gz
The JRE files are installed in a directory called jre1.7.0_<version> in the current directory.
4. Delete the .tar.gz file if you want to save disk space.

Installation of the 64-bit JRE on RPM-based Linux Platforms
Thisprocedure installs the Java Runtime Environment (JRE) for 64-bit RPM-based Linux platforms, such as Red Hat and SuSE, using an RPM binary file (.rpm) in the system location. You must be root to perform this installation.
These instructions use the following file:
jre-7u<version>-linux-x64.rpm
1. Download the file. Before the file can be downloaded, you must accept the...
