Download
- Go to http://java.com
- Click on Free Java
Download button
- There are two types of installation packages. Linux RPM package or
Linux self extracting binary file. Download the package that best suits
your needs.
Note: Linux RPM (Redhat Package Manager) uses RPM
to install the JRE. In order to use this method, you need to have RPM available
on your system. Otherwise use the other option.
- Click the appropriate Download button to download the package that best
suits your needs. You can download the file to any of the directories on your
system.
- After download verify: For Linux self extracting binary file
- Name of the file is jre-1_6_0_02-linux-i586.bin
- Size is approximately 15.8 MB
For Linux RPM packages
- Name of the file is jre-1_6_0_02-linux-i586-rpm.bin
- Size is approximately 15.26 MB

package
Note: For any text on this page containing the
following notation, you must substitute the appropriate Java SE Runtime
Environment update version number for the notation. <version>
For
example, if you are downloading update 1.6.0_01, the following command:
./jre-6<version>-linux-i586.bin
would become:
./jre-6u1-linux-i586.bin
To install the Linux (self-extracting)
file
Follow these instructions:
- At the terminal: Type:
su
- Enter the root password.
- Change to the directory in which you want to install. Type:
cd
<directory path name>
For example, to install the software in the
/usr/java/ directory, Type:
cd /usr/java/
Note about root
access: To install the JRE in a system-wide location such as /usr/local, you
must login as the root user to gain the necessary permissions. If you do not
have root access, install the JRE in your home directory or a subdirectory for
which you have write permissions.
- Change the permission of the file you downloaded to be executable.
Type:
chmod a+x jre-6u<version>-linux-i586.bin
- Verify that you have permission to execute the file. Type:
ls -l
- Start the installation
process.Type:
./jre-6u<version>-linux-i586.bin
This
displays a binary license agreement. Read through the agreement. Press the
spacebar to display the next page. At the end, enter yes to proceed with
the installation.
- The JRE is installed into its own directory. In this example, it is
installed in the /usr/java/jre1.6.0_<version> directory. When the
installation has completed, you will see the word
Done.
- The JRE is installed in jre1.6.0_<version> sub-directory under the
current directory. In this case, the JRE is installed in the
/usr/java/jre1.6.0_<version> directory. Verify that the
jre1.6.0_<version> sub-directory is listed under the current
directory. Type:
ls
The installation is now
complete. Skip to the Enable and
Configure section.
To install the Linux RPM (self-extracting)
file
Follow these instructions:
- At the terminal: Type:
su
- Enter the root password.
- Change to the directory in which you want to install. Type:
cd
For example, to install the software in the /usr/java/
directory, Type:
cd /usr/java
Note about root access: To install the JRE in a system-wide location such as/usr/local, you must
login as the root user to gain the necessary permissions. If you do not have
root access, install the JRE in your home directory or a subdirectory for which
you have write permissions.
- Change the permission of the file you downloaded to be executable.
Type:
chmod a+x jre-6u<version>-linux-i586-rpm.bin
- Start the installation process.
Type:
./jre-6u<version>-linux-i586-rpm.bin
This displays
a binary license agreement. Read through the agreement. Press the spacebar to
display the next page. At the end, enter yes to proceed with the
installation.
- The installation file creates jre-6u<version>-linux-i586.rpm file in the current directory.
- Run the RPM command at the terminal to install the packages. Type:
rpm
-iv jre-6u<version>-linux-i586.rpm
- The JRE is installed in jre1.6.0_<version> sub-directory under the
current directory. In this case, the JRE is installed in the
/usr/java/jre1.6.0_<version> directory. Verify that the
jre1.6.0_<version> sub-directory is listed under the current
directory. Type:
ls
The installation is now
complete. Go to the Enable and
Configure section.

- Go to the plugins sub-directory under the Mozilla installation
directory
cd <Mozilla installation directory>/plugins
- In the current directory, create a symbolic link to the JRE
ns7/libjavaplugin_oji.so file Type:
ln -s <JRE installation
directory>/plugin/i386/ns7/libjavaplugin_oji.so
Example:
- If Mozilla is installed in this directory:
/usr/lib/mozilla-1.4/
- and if the JRE is installed at this directory:
/usr/java/jre1.6.0
- Then type at the terminal to go to the browser plug-in directory:
cd
/usr/lib/mozilla-1.4/plugins
- Enter the following command to create a symbolic link to the Java Plug-in
for the Mozilla browser.
ln -s
/usr/java/jre1.6.0/plugin/i386/ns7
/libjavaplugin_oji.so .
- Start Mozilla browser or restart it if it is already running. Note that if
you have other Mozilla components (ie: Messenger, Composer, etc) running, you
will need to restart them as well.
- Go to Edit > Preferences. Under Advanced category
> Select Enable Java
Mozilla 1.2, Netscape 6 and later
- Go to the plugins sub-directory under the Netscape directory
cd
<Mozilla1.2>/plugins
- Create a symbolic link to the ns7-gcc29/libjavaplugin_oji.so
file:
ln -s <JRE>/plugin/i386/ns7-gcc29/libjavaplugin_oji.so
Example:
- If Netscape is installed at this directory:
/usr/lib/Mozilla1.2/
- And if the JRE is installed at this directory:
/usr/java/jre1.5.0
- Then type at the terminal to go to the browser plug-in directory:
cd
/usr/lib/Mozilla1.2/plugins
- Enter the following command to create a symbolic link to the Java Plug-in
for the Mozilla browser.
ln -s
/usr/java/jre1.6.0/plugin/i386/ns7-gcc29
/libjavaplugin_oji.so .
- Start Mozilla browser or restart it if it is already running. Note that if
you have other Mozilla components (ie: Messenger, Composer, etc) running, you
will need to restart them as well.
- Go to Edit > Preferences. Under Advanced category
> Select Enable Java
Firefox
- Go to the plugins sub-directory under the Firefox installation
directory
cd <Firefox installation directory>/plugins
- In the current directory, create a symbolic link to the JRE
ns7/libjavaplugin_oji.so file Type:
ln -s <JRE installation
directory>/plugin/i386/ns7/libjavaplugin_oji.so
Example:
- If Firefox is installed at this directory:
/usr/lib/firefox-1.4/
- And if the JRE is installed at this directory:
/usr/java/jre1.6.0
- Then type at the terminal to go to the browser plug-in directory:
cd
/usr/lib/firefox-1.4/plugins
- Enter the following command to create a symbolic link to the Java Plug-in
for the Mozilla browser.
ln -s
/usr/java/jre1.6.0/plugin/i386/ns7
/libjavaplugin_oji.so
In the command line above, use ns7-gcc29 if Firefox was
compiled with gcc2.9.
If you install Firefox 1.5 or later, you can
enable the Java Console menu item in the Tools menu. Change directories to the
Firefox extensions directory, then unzip ffjcext.zip there.
cd
/usr/lib/firefox-1.4/extensions
unzip
/usr/java/jre1.6.0/lib/deploy/ffjcext.zip
-
Start the Firefox browser, or restart it if it is already up.
In Firefox, type about:plugins in the Location bar to confirm
that the Java Plugin is loaded. If the version is Firefox 1.5 or later, click
the Tools menu to confirm that Java Console is
there
