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. Recommended and required patches are now hosted for download on the SunSolve website at 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 SDK Installation Instructions

To install the 32-bit Java 2 SDK on either x86 or SPARC processors, follow the installation instructions below.

If you want to install the 64-bit Java 2 SDK on your SPARC platform, you must follow a two-step procedure. First, install the 32-bit Java 2 SDK using the installation instructions below. Second, install the supplemental support for 64-bit operation by following the 64-bit Installation Instructions.

Java 2 SDK 1.4.1 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. This package can be installed by anyone (not only root users), and it can be installed in any location. It will not displace the system version of the Java platform suppled by the Solaris operating environment (unless you intentially install it in the same location as the system's Java platform, which requires you to be root user). If you are using this file, see Self-Extracting Binary below.

• A .tar.Z file containing Solaris SUNW* packages to be installed with the pkgadd utility. The SUNW pakcages require root access to install, and they install by default in a location such that they replace the system version of the Java platform supplied by the Solaris operating environment. If you are using this bundle, see Installation of Packages below.

Java 2 SDK 1.4.1 will not automatically become the default Java platform. To make Java 2 SDK 1.4.1 the default Java platform, see the note on Selecting the Default Java Platform at the end of this file.

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, use Installation of Packages below.

1. Check the download file size to ensure that you have downloaded the full, uncorrupted software bundle.

Before you download a file, notice that its byte size is provided on the download page on the web site. 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 processors:
chmod +x j2sdk-1_4_1-solaris-sparc.sh

On x86 processors:
chmod +x j2sdk-1_4_1-solaris-i586.sh

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

4. Run the self-extracting binary.

Launch the self-extracting binary file. The binary code license will be displayed, and you will be prompted to agree to its terms. The Java 2 SDK files will be installed in a directory called j2sdk1.4.1.

System preferences -- By default, the installation script configures the system such that the backing store for system preferences is created inside the Java 2 SDK's installation directory. If the SDK 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:

j2sdk-1_4_1-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 at http://java.sun.com/j2se/1.4.1/docs/guide/lang/preferences.html for more information about preferences in the Java platform.

Installation of Packages

Use these instructions if you want to use the pkgadd 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 above.

Please note that there is a bug in the uninstall scripts associated with some of the Java 2 SDK packages. See the Release Notes for more information.

1. Check the download file size to ensure that you have downloaded the full, uncorrupted software bundle.

Before you download a file, notice that its byte size is provided on the download page on the web site. 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 processors:
zcat j2sdk-1_4_1-solaris-sparc.tar.Z | tar -xf -

On x86 processors:
zcat j2sdk-1_4_1-solaris-i586.tar.Z | tar -xf -

This will create several packages (SUNWj3dmo, SUNWj3dev, SUNWj3man, SUNWj3rt, plus SUNWj3jmp containing Japanese man pages) along with the product license, README, and other release documentation.

3. Become root by running su and entering the super-user password.

4. Uninstall Previous Installation of Java 2 SDK

Note: The default installation location for Java 2 SDK's 1.3.0, J2SE 1.3.1, and 1.4.0 releases is /usr/j2se. That is the same location in which Java 2 SDK 1.4.1 is installed. To clear the way for installation J2SE 1.4.1, in this step you will uninstall any of these previous releases that you may have installed. Skip this step if you have not installed any of these previous releases or if you intend to install Java 2 SDK 1.4.1 in a non-default location.

If you have previously installed the packages for Java 2 SDK 1.3.0, 1.3.1, or 1.4.0, remove them.

pkgrm SUNWj3dmo SUNWj3man SUNWj3dev SUNWj3rt, 

If you have previously installed packages SUNWlj3dv and SUNWlj3rt for localization support in Java 2 SDK 1.3.0, you should also remove them:

pkgrm SUNWlj3dv SUNWlj3rt

If you have previously installed the Japanese man page packages for Java 2 SDK 1.3.0 or 1.3.1, remove them also:

pkgrm SUNWjej3m SUNWjpj3m SUNWjuj3m

If your /usr/java symbolic link was pointing to the Java 2 SDK 1.2.2 installation at /usr/java1.2, you may want to update it to point /usr/j2se where Java 2 SDK 1.4.1 will be installed.

5. Run the pkgadd command to install the packages.

On either x86 or SPARC processors:
pkgadd -d . SUNWj3rt SUNWj3dev SUNWj3man SUNWj3dmo

This will install the Java 2 SDK 1.4.0 into /usr/j2se; see the pkgadd(1) and admin(4) man pages for information on installing the SDK in a non-default location.

6. For Japanese users

If you previously installed the man page packages from Java 2 SDK 1.3.0 or 1.3.1, remove them.

pkgrm SUNWjej3m SUNWjpj3m SUNWjuj3m

If you have version 1.4.0 Japanese man pages installed, you will need to remove them:

pkgrm SUNWj3jmp

Then run the pkgadd command to install the new Japanese man page package:

pkgadd -d . SUNWj3jmp

7. Delete the tar files and extracted directories.

8. Exit the root shell.

Java Plug-in Installation Instructions

http://java.sun.com/j2se/1.4/docs/guide/plugin/index.html

To install/register the Java Plug-in product you have two choices:

• You can do it manually;
• or you can do it automatically via the ControlPanel script.

Java Web Start Installation Instructions

Java 2 SDK 1.4.0 includes the Java Web Start product. Inside the SDK's jre directory you will find a ZIP file named javaws-1_2-solaris-sparc-i.zip on SPARC platforms and javaws-1_2-solaris-i586-i.zip on x86 platforms. Move this file to a location where you want to install the Java Web Start product (preferably outside the Java 2 SDK installation). Unzip the file. One of the files extracted will be install.sh. Run this script to install the Java Web Start product.

jre/lib/sparc/client/libjvm.so (on SPARC platforms)
jre/lib/i386/client/libjvm.so (on x86 platforms)

jre/lib/sparc/server/libjvm.so (on SPARC)
jre/lib/i386/server/libjvm.so (on x86)

Prior to the Solaris 8 release, the /usr/java symbolic link pointed to /usr/java1.1 if both JDK 1.1 and Java 2 SDK 1.2.2 were installed, making JDK 1.1 the default Java platform. Starting with the Solaris 8 release, the /usr/java symbolic link points to /usr/java1.2 by default if both JDK 1.1 and Java 2 SDK 1.2.2 are installed, making Java 2 SdK 1.2.2 the default Java platform.

Because 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 Java 2 SDK 1.4.1, Java 2 SDK 1.3.1, Java 2 SDK 1.2.2, or JDK 1.1, but users and applications might want to be selective about which Java platform installation they use.

If you want to use JDK 1.1, /usr/java1.1/bin should be on your PATH before /usr/bin. If you want to use Java 2 SDK 1.4.1, /usr/j2se/bin should be on your PATH before /usr/bin.

It is possible for root users to make Java 2 SDK 1.4.1 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. See the online compatibility documentation for information about incompatibilities between Java 2 SDK 1.4.1 and earlier releases.
