Installation Notes
Java 2 SDK, Standard Edition,
Version 1.3.0
for the Solaris Operating Environment
|
|
Installation Instructions
Prior to installing the Java 2 SDK, you should insure that you have
installed the full set of required patches needed for support of
this release. See also the note about
the location of the Java HotSpot libjvm.so
files.
The Java 2 SDK, Standard Edition, v1.3.0, is available in
two installation formats.
- A self-extracting binary file which can be used to install the
Java 2 SDK in a location chosen by the user. If you are using this
file, see Self-Extracting Binary.
- A .tar.Z file containing Solaris packages to be installed
with the pkgadd utility. If you are using this bundle, see
Installation of Packages.
Java Plug-in installation instructions are located
below.
Note: J2SE 1.3.0 will not be the default platform when installed.
To make J2SE 1.3.0 the default Java platform, see the note on
Selecting the Default Java Platform at the
end of this file.
Note: For any lines on this page containing the following
notation, you must substitute the appropriate update version number for the
notation.
<version number>
For example, if you are downloading update 1.3.0_03, the following command:
chmod +x j2sdk-1_3_0_<version number>-solsparc.bin
would become:
chmod +x j2sdk-1_3_0_03-solsparc.bin
Installation of Self-Extracting Binary
Use these instructions if you want to use the self-extracting
binary file to install the Java 2 SDK. If you want to install
Solaris packages comprising the SDK, see Installation
of Packages.
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.
Make sure that execute permissions are set on
the self-extracting binary:
On SPARC:
chmod +x j2sdk-1_3_0_<version number>-solsparc.bin
On x86:
chmod +x j2sdk-1_3_0_<version number>-solx86.bin
3.
Change directory to the location where you would
like the files to be installed.
4.
Run the self-extracting binary.
The files will be installed in
a subdirectory called j2sdk1_3_0_<version number>. After
the installation is finished, the subdirectory can be renamed as
desired.
Installation of Packages
Use these instructions if you want to use the pkdadd utility to install
the Solaris packages for the Java 2 SDK. If you want to use
the self-extracting binary file instead, see
Self-extracting Binary.
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.
Extract the contents of the compressed tar file:
On SPARC:
zcat j2sdk-1_3_0_<version number>-solsparc.tar.Z | tar -xf -
On x86:
zcat j2sdk-1_3_0_<version number>-solx86.tar.Z | tar -xf -
This will create four packages (SUNWj3dmo, SUNWj3dev, SUNWj3man,
and SUNWj3rt) along with the product license, README, and
other release documentation.
Note: The package for the J2SE demos has changed names. In
this release it is named SUNWj3dmo; previously it was named SUNWj3dem.
3.
Become root:
su
4.
Run the pkgadd command to install the packages:
pkgadd -d . SUNWj3rt SUNWj3dev SUNWj3man SUNWj3dmo
This will install the SDK into /usr/j2se; see the pkgadd(1)
and admin(4) man pages for information on installing the SDK in
an alternate location.
5.
Delete the tar files and extracted directories.
6.
Exit the root shell.
7.
Install the Java Plug-in Product
-
Set the NPX_PLUGIN_PATH environment variable to the directory containing the
javaplugin.so file.
On SPARC platforms, the default location
of javaplugin.so for the package installation is in this directory:
/usr/j2se/jre/plugin/sparc/ns4/
On Intel platforms, the default location is this directory:
/usr/j2se/jre/plugin/i386/ns4/
- For Netscape 6 browsers: Create a symbolic link in the Netscape plugins directory
If (and only if) you are using Netscape 6, you will need to
create a symbolic link in the Netscape plugins directory
to the path of the libjavaplugin_oji.so file. In the package
installation of J2SE 1.3.1 Beta, this file is located
at /usr/j2se/jre/plugin/<arch>/ns600/libjavaplugin_oji.so,
where <arch> is either sparc or i386,
depending on your platform. For example:
cd ${NETSCAPE6}/bin/plugins
ln -s ${JRE}/plugin/sparc/ns600/libjavaplugin_oji.so .
- For
all Netscape browsers: Start your Netscape browser, or restart
it if it is already up.
- For all Netscape browsers: Restart your browser a second time.
Restarting the browser a second time is necessary because of bug
4358142.
Location of libjvm.so files
If you use the Invocation API to launch an application directly rather
than using the Java application launcher, be sure to use the
correct paths to invoke the Java HotSpot Client VM or Java HotSpot
Server VM as desired. The path within the SDK to the Java HotSpot
Client VM is
jre/lib/sparc/client/libjvm.so (on SPARC)
jre/lib/i386/client/libjvm.so (on x86)
The path to the Java HotSpot Server VM is
jre/lib/sparc/server/libjvm.so (on SPARC)
jre/lib/i386/server/libjvm.so (on x86)
The Exact VM and Classic VM are no longer part of the Java 2 platform,
and legacy code that uses the Invocation API to launch an application
based on old paths to the Exact or Classic VMs will not work.
Selecting the Default Java Platform
The /usr/java symbolic link is used to define the default Java environment
on a Solaris system when more than one Java environment is installed.
Currently, JDK 1.1 is installed in /usr/java1.1, J2SE 1.2.2 is
installed in /usr/java1.2, and J2SE 1.3.0 is installed in
/usr/j2se.
Prior to the Solaris 8 release, the /usr/java symbolic link pointed to
/usr/java1.1 if both JDK 1.1 and J2SE 1.2.2 were installed. Starting wi
th the Solaris 8 release, the /usr/java symbolic link points to
/usr/java1.2 by default if both JDK 1.1 and J2SE 1.2.2 are installed.
Since there are symbolic links in /usr/bin (also known as /bin
) that use /usr/java (for example, /usr/bin/java refers to /usr/java/bin/java), this /usr/java link can change
the default Java installation seen by most users.
Many Java applications run on any of J2SE 1.3.0, J2SE 1.2.2, or JDK 1.1,
but users and applications might want to be selective about which
Java installation they use.
Java users that want to use JDK 1.1 should add /usr/java1.1/bin
to their PATH settings before /usr/bin. Java users that
want to use J2SE 1.3.0 should add /usr/j2se/bin to their PATH
settings before /usr/bin. Also, depending on the situation, you
might need to make changes to other environment variables such as
CLASSPATH, LD_LIBRARY_PATH, or JAVA_HOME,
although none of these environment variables are required.
It is possible for root users to make J2SE 1.3.0 the default Java platform
by modifying the /usr/java symbolic link to point to
/usr/j2se. However, changing the symbolic link in this manner may
cause problems for some Java applications that are expecting to use earlier
versions of the Java platform.
