Getting Started

    Java 2 Runtime Environment, v. 1.2.2-001 for SCO Operating Systems

The JavaTM 2 Runtime Environment, v. 1.2.2-001 for SCO Operating Systems, also known as the JRE 1.2.2 for SCO, package name java2jre2, contains the Java virtual machine, runtime class libraries, and Java application launcher that are necessary to run programs written in the Java programming language. It is not a development environment and does not contain development tools such as compilers or debuggers. For development tools, use the J2SDK 1.2.2 for SCO.

The purpose of the JRE package is so that licensed independent software vendors (ISVs) can bundle it with their Java application, if desired. That way, the application and the Java version it has been tested on can be installed together on customer machines, rather than relying on whatever Java version is currently installed on those machines.

The java2jre2 package is by default installed in /usr/jre/, with that actually being a symbolic link to /opt/jre2-1.2.2/. Unlike the java2* packages, however, it is possible for an ISV or system administrator to change where the JRE is installed. See the J2SDK 1.2.2 for SCO Release Notes for instructions on how to do this.

Note again that the JRE package is intended for use by ISVs; if you are an end user, you should simply use the regular java2sdk2 package (and java2pls2 package if desired) instead.

System Requirements

For a complete description of platform availability and system requirements see the J2SDK 1.2.2 for SCO Release Notes.

Installation

The JRE 1.2.2 for SCO may be installed and run on UnixWare 7 Release 7.1.x and on SCO OpenServer Release 5, if the UDK Compatibility Module for SCO OpenServer has been installed.

If you are installing the JRE on UnixWare 7, the freefonts package must be installed first. This package is available from the free SCO Open License Software Supplement (also known as SCO SkunkwareTM). The Supplement is distributed as a CD-ROM in the media kit for SCO operating systems, and the package is also available for free download from http://www.sco.com/skunkware/ (look in the Graphics/Viewers section). See the J2SDK 1.2.2 for SCO Release Notes for more detailed information about the use of different fonts.

Once you have downloaded the product file from the Download page, perform the following steps as root:

  1. Move the file to a preferred installation directory, making sure there is enough space available:
    mv  java2jre2.pkg.Z  /tmp
  2. Change to the installation directory:
    cd  /tmp
  3. Uncompress the file:
    uncompress  java2jre2.pkg.Z
  4. If you are installing the JRE 1.2.2 for SCO on OpenServer , you should first determine if you have the correct version of the compatibility module for that platform. To do this, enter:
    pkginfo -l  OSRcompat
    If there is no compatibility module installed, or you have an older version, you can download the latest version from the SCO Download page or extract it from the latest UnixWare and OpenServer Development Kit CD available in the media kit. To remove an older version, enter:
    pkgrm  OSRcompat
    To install a new compatibility module, extract and uncompress the file as described above and enter:
    pkgadd  OSRcompat

  5. Install the package as described in the J2SDK 1.2.2 for SCO Release Notes:
    pkgadd  -d  /tmp/java2jre2.pkg
  6. When you you have completed the installation, you will probably want to remove the download package from the /tmp directory.
