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 Java. In order to use this method, you need to have RPM available on your system. Otherwise use the other option.
Note: The instructions below are for installing Java 1.4.2_04. If you're installing another version, make sure you change the version number appropriately when you type the commands at the terminal.
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 Java 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 Java 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 j2re-1_4_2_04-linux-i586.bin
Verify that you have permission to execute the file. Type: ls -l
Start the installation process.Type: ./j2re-1_4_2_04-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.
Java is installed into its own directory. In this example, it is installed in the /usr/java/j2re1.4.2_04 directory. When the installation has completed, you will see the word Done.
Java is installed in j2re1.4.2_(version number) sub-directory under the current directory. In this case, Java is installed in the /usr/java/j2re1.4.2_04 directory. Verify that the j2re1.4.2_04 sub-directory is listed under the current directory. Type: ls
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 Java 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 Java 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 j2re-1_4_2_04-linux-i586-rpm.bin
Start the installation process. Type: ./j2re-1_4_2_04-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 j2re-1_4_2_-linux-i586.rpm file in the current directory.
Run the RPM command at the terminal to install the packages. Type: rpm -iv j2re-1_4_2_04-linux-i586.rpm
Java is installed in j2re1.4.2_(version number) sub-directory under the current directory. In this case, Java is installed in the /usr/java/j2re1.4.2_04 directory. Verify that the j2re1.4.2_04 sub-directory is listed under the current directory. Type: ls
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 Java ns610-gcc32/libjavaplugin_oji.so file Type:
ln -s <Java installation directory>/plugin/i386/ns610-gcc32/libjavaplugin_oji.so
Example:
If Mozilla is installed in this directory: /usr/lib/mozilla-1.4/
and if Java is installed at this directory: /usr/java/j2re1.4.2_04
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/j2re1.4.2_04/plugin/i386/ns610-gcc32
/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
Go to the plugins sub-directory under the Netscape directory cd <Netscape>/plugins
Create a symbolic link to the ns610/libjavaplugin_oji.so file:
ln -s <JRE>/plugin/i386/ns610/libjavaplugin_oji.so
Example:
If Netscape is installed at this directory: /usr/lib/Netscape6/
And if Java is installed at this directory: /usr/java/j2re1.4.2_04
Then type at the terminal to go to the browser plug-in directory: cd /usr/lib/Netscape6/plugins
Enter the following command to create a symbolic link to the Java Plug-in for the Mozilla browser. ln -s /usr/java/j2re1.4.2_04/plugin/i386/ns610
/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
Test Installation
To test that Java is installed, enabled and working properly on your computer, run this test applet from our web site:
Test your Java installation Java installation and configuration is successful if you can see the animation of the Duke logo image.
