Section 2: Installing and Configuring Java on Linux

Installing the Java™ 2 Runtime Environment 5

3. Launch the installation scripts by using the following commands from the directory in

which the file is located:

a. Type

chmod a+x j2re-1_4_1_<version number>-linux-i586.bin

and press x

b. Type

./j2re-1_4_1_<version number>-linux-i586.bin

and press x

4. Agree to the binary license agreement. The install script installs JRE in a directory

called j2re1.4.1_<version number> in the current directory.

Regarding System Preferences

By default, the installation script configures the system such that the backing store for

system preferences is created inside the Java 2 JRE's installation directory. If the JRE is

installed on a network-mounted drive, it and the system preferences can be exported for

sharing with Java runtime environments on other machines. Alternately, root users can use

the -localinstall option when running the installation script, as in this example:

j2re-1_4_1_<version number>-linux-i586.bin -localinstall

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 defined as a

“root user” for the -localinstall option to work.

See the Preferences API documentation for more information about preferences in the

Java platform.

Regarding Root Access

If you choose to install the Java 2 Runtime Environment into system-wide location such as

/usr/local, you must first login as “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.
