System Requirements:

Java 2 Runtime Environment, Standard Edition, v. 1.4.2 requires Solaris
7, Solaris 8, or Solaris 9 Operating Systems.

Note that for x86 processors, display color depth should be set to 16 bit
or higher.

Prior to installing the Java 2 Runtime Environment, you should ensure
that you have installed the full set of required patches needed for
support of this release. Recommended and required patches are
available for download from the SunSolve website.
At the time of this writing this is the J2SE patch URL:
http://sunsolve.sun.com/pub-cgi/show.pl?target=patches/J2SE

See also Solaris Font Package Requirements for information about which
font packages should be on your system.

Java 2 Runtime Environment Installation Instructions:

The Java 2 Runtime Environment (J2RE), Standard Edition, v1.4.2 comes in
the form of a self-extracting binary file. Follow the instructions below
to install the J2RE.

Note that Java Plug-in and Java Web Start are automatically installed
with the JRE, but Java Plug-in needs to be registered with the browser.
Instructions for doing so can be found below at Java Plug-in Browser
Registration Instructions.

64-bit support for the Java 2 Runtime Environment is available for SPARC
processor platforms in a separate download. Installation instructions
for 64-bit support are in a separate document.

    Note: For any text on this page containing the following notation,
    you must substitute the appropriate Java RE update version number
    for the notation.

      <version>

    For example, if you are downloading update 1.4.2_01, the following
    command:

      $ chmod +x j2re-1_4_2_<version>-solaris-sparc.sh

    would become:

      $ chmod +x j2re-1_4_2_01-solaris-sparc.sh

1. Check the download file size

    You can download to any directory you choose; it does not have to be
    the directory where you want to install the J2RE.

    Before you download the file, notice its byte size provided on the
    download page on the web site. Once the download has completed,
    compare that file size to the size of the downloaded file to make
    sure they are equal.

2. Make sure that execute permissions are set on the self-extracting
   binary:

    On SPARC processors:
    $ chmod +x j2re-1_4_2_<version>-solaris-sparc.sh

    On x86 processors:
    chmod +x j2re-1_4_2_<version>-solaris-i586.sh

3. Change directory to the location where you would like the files
   to be installed.

    The next step installs the J2RE into the current directory. 

4. Run the self-extracting binary.

    Execute the downloaded file, prepending the path to it. For example,
    if the downloaded file is in the current directory, prepend it with
    "./":

    $ ./j2re-1_4_2_<version>-solaris-sparc.sh

    On x86 processors:
    ./j2re-1_4_2_<version>-solaris-i586.sh

    The binary code license is displayed, and you are prompted to agree
    to its terms.

    The J2RE files are installed in a directory called
    j2re1.4.2_<version> in the current directory.

Note about System Preferences - By default, the installation script
configures the system such that the backing store for system preferences
is created inside the J2RE's installation directory. If the J2RE 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:

     $ ./j2re-1_4_2_<version>-solaris-sparc.sh -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 root user for the -localinstall option to work.

See the Preferences API documentation for more information about
preferences in the Java platform.


Java Plug-in Browser Registration Instructions:

See Java Plug-in Browser Registration Instructions in the Installation
Notes for Java2 SDK, Standard Edition.

Java Web Start Installation Notes:

    This JRE release includes Java Web Start; Java Web Start is
    installed automatically with the JRE. But note the following:

        + Compatibility: The release of Java Web Start that comes with
          this SDK/JRE can be run on SDK/JRE 1.2.2 or later. It will not
          work with SDK/JRE 1.1.x or earlier.

        + Upgrading from Previous Versions: This new release will
          overwrite previous installations and automatically update
          browsers to use this new release. The configuration files and
          program files folder used by Java Web Start have changed, but
          all your settings will remain intact after the upgrade, since
          Java Web Start will translate your settings to the new form.

        + Using Java Web Start with Netscape 6.x/7.x: For Netscape
          6.x/7.x users, setup the Java Web Start MIME type (JNLP) in
          the Edit->Preferences->Navigator->Helper Applications section.

          The file extension is:  jnlp
	  MIME Type is:           application/x-java-jnlp-file
	  
	  It should be handled by the javaws executable file in your
	  Java Web Start directory.  Also note that, due to a problem
	  with the JavaScript in Netscape 6.x/7.x, you must use the
	  non-JavaScript version of the demos page.

        + pkgadd Utility Use: If you use the pkgadd utility to
          install the Solaris packages for Java 2 SDK/JRE 1.4.2, a
          symbolic link for ../j2se/jre/javaws/javaws will be created
          in /usr/bin.

    Note About Location of Java VM Library Files:
    If you want to use the Invocation API to launch an application
    directly rather than using the Java application launcher, please
    see Location of VM Library Files (libjvm.so).
