Java 2 Runtime Environment, Standard Edition
To print on Linux, the /usr/sbin/lpc utility must be installed. This is a standard Linux utility. On RedHat 7.1, for example, this utility is in the "LPRng-3.7.4-22 RPM" package.
Check your version of glibc using the following command:
You should have about 75 megabytes of free disk space before attempting to install the Java 2 SDK software.
Most testing of Java RE 1.4.1 for Linux in the English-locale has been conducted on Red Hat 7.2, with kernel patch 2.4.9-31. Most testing in non-English locales has been conducted on Red Hat 7.1. However, Java RE 1.4.1 has undergone limited testing on these other Linux operating systems:
rpm --install compat-libstdc++-6.21-22.214.171.124.i386.rpm
It is not necessary to manually install compat-libstdc++-6.21-126.96.36.199.i386.rpm if you are using RedHat Linux 7 Workstation.
- An apparent bug in glibc 2.2-7 causes invalid hostnames of the form a.b.c.d.e to be resolved as a valid address (a.b.c.d or a.b.c.e). This bug means that, on platforms that use glibc 2.2-7, methods such as java.net.InetAddresss.getByName(String host) do not always throw UnknownHostException, as they should, when the hostname is invalid.

Note: For any lines on this page containing the following notation, you must substitute the appropriate Java RE update version number for the notation.For example, if you are downloading update 1.4.1_01, the following command:
<version number>would become:
./j2re-1_4_1_01-linux-i586.binThe Java 2 Runtime Environment (Java RE), Standard Edition, v1.4.1 is available in two installation formats.
The bundles for both installation formats are packaged in a .bin shell script that displays the product license agreements before actual installation.
- A self-extracting binary file, j2re-1_4_1_<version number>-linux-i586.bin which can be used to install the Java 2 Runtime Environment in a location chosen by the user. If you are using this file, see Self-Extracting Binary .
- The file j2re-1_4_1_<version number>-linux-i586-rpm.bin that contains RPM packages comprising the Java 2 Runtime Environment. If you are using this bundle, see Installation of RPM File .
After you install the Java RE, you will also be able to install the Java Plug-in and Java Web Start products. Java Plug-in installation instructions and Java Web Start installation instructions are included below.
Use the following instructions if you want to use the self-extracting binary file to install the Java 2 Runtime Environment. If you want to install RPM packages instead, see Installation of RPM File.
1. Check the download file sizeBefore you download a file, notice that its byte size is provided on the download page. Once the download has completed, check that you have downloaded the full, uncorrupted software file.
2. Change to the directory you want to install into.For example, if you want to install the software in the /usr/java/ directory, then execute:cd /usr/java
3. Run j2re-1_4_1_<version number>-linux-i586.bin and agree to the license it displays.Launch the installation scripts by using the following commands from the directory in which the file is located:Note about System Preferences - By default, the installation script configures the system such that the backing store for system preferences is created inside the Java 2 SDK's installation directory. If the SDK is installed on a network-mounted drive, it and the system preferences can be exported for sharing with Java runtime environments on other machines. As an alternative, root users can use the -localinstall option when running the installation script, as in this example:The script displays a binary license agreement, which you are asked to agree to before installation can proceed. Once you have agreed to the license, the install script installs the Java RE in a directory called j2re1.4.1_<version number> in the current directory.chmod a+x j2re-1_4_1_<version number>-linux-i586.bin ./j2re-1_4_1_<version number>-linux-i586.bin
This option causes the system preferences to be stored in the /etc directory from where they can be shared only by VMs running on the local machine. You must be root user for the -localinstall option to work.j2re-1_4_1_<version number>-linux-i586.bin -localinstall
See the Preferences API documentation for more information about preferences in the Java platform.
Note about Root Access - If you choose to install the Java 2 Runtime Environment into system-wide location such as /usr/local, you must first become root to gain the necessary permissions. If you do not have root access, simply install the Java 2 Runtime Environment into your home directory, or a subdirectory that you have permission to write to.
Use these instructions if you want to install Java 2 Runtime Environement in the form of RPM packages. If you want to use the self-extracting binary file instead, see Self-Extracting Binary above.
1. Check the download file size.Before you download a file, notice that its byte size is provided on the download page. Once the download has completed, check that you have downloaded the full, uncorrupted software file.
2.

Once you have agreed to the license, the install script creates the file j2re-1_4_1_<version number>-linux-i586.rpm in the current directory.chmod a+x j2re-1_4_1_<version number>-linux-i586-rpm.bin ./j2re-1_4_1_<version number>-linux-i586-rpm.bin
3. Become root by running the su command and entering the super-user password.
4. Run the rpm command to install the packages:The following command installs the packages comprising the Java 2 Runtime Environment.rpm -iv j2re-1_4_1_<version number>-linux-i586.rpm
5. Exit the root shell.
See Java Plug-in Installation Instructions in the Installation Notes for Java 2 SDK, Standard Edition, for Linux.
Java RE 1.4.1 includes the Java Web Start product. Inside the Java RE's top-level directory you will find a ZIP file named javaws-1_2_0_<version number>-linux-i586-i.zip. The <version number> notation refers to the current Java Web Start version number.
Move this file to a location where you want to install the Java Web Start product (preferably outside the Java RE installation). Unzip the file. One of the files extracted is install.sh. Run this script to install the Java WebStart product.
