The Java 2 Runtime Environment,
v. 1.3.0_02, for Caldera UNIX Operating Systems,
also known as the JRE 1.3 for Caldera UNIX (package java2jre3
), is the minimum standard Java platform for running
Java programs.
It contains the Java virtual machine, JIT compiler,
Java core classes and supporting files, and Java application launcher.
This package matches
the Sun product configuration of the Java Runtime Environment (JRE).
The JRE does not contain any of
the development tools (such as appletviewer or javac) or classes that
pertain only to a development environment. For such tools, use the
J2SDK 1.3 for Caldera UNIX.
One particular 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.
Note that there was an earlier release of J2SE 1.3.0_02 for Caldera UNIX
before this one. It was documented as a final release for Open UNIX 8 and
UnixWare 7, but as only a beta release for SCO OpenServer 5.
Its build version string, as shown by the
java -version
command, was
*FCS-OU8*FCS-UW7*BETA-OSR5*:010602-10:46
.
This newer release is a final release for SCO OpenServer 5, and also contains
fixes for Caldera-specific problems on Open UNIX 8 and UnixWare 7
discovered since the earlier release went out.
This newer release has a build version string of
*fixes-OU8*fixes-UW7*FCS-OSR5*:<later-date-and-time>
.
For
complete details regarding system requirements, prerequisite packages
and supported platforms, see the Java 2 Standard Edition (J2SE), v. 1.3.0_02
for Caldera UNIX Release Notes that are distributed along with the
java2jre3
package and installed in /usr/java2
in both HTML and text format.
The Release Notes are also available for download from this download page
for added convenience.
The java2jre3
package is by default installed in
/usr/jre2/
, with that actually being a symbolic link
to /opt/jre2-1.3/
.
Unlike the java2sdk3
and java2pls3
packages, however, it is possible
for an ISV or system administrator to change where the JRE is installed.
See the J2SE Release Notes for instructions on how to do this.
The JRE 1.3 product is distributed as a compressed pkgadd
datastream format. To download and install the JRE:
mv java2jre3.pkg.Z /tmp1
cd /tmp1
uncompress java2jre3.pkg.Z
pkgadd
.
pkgadd -d /tmp1/java2jre3.pkg
