System Requirements

Prior to installing the Java 2 Runtime Environment, you should insure that you have installed the full set of required patches needed for support of this release.

Installation Instructions

See also the note about the location of the Java HotSpot libjvm.so files.

       <version number>

      chmod +x j2re-1_3_1_<version number>-solsparc.sh

      chmod +x j2re-1_3_1_01-solsparc.sh

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.

If the file size doesn't match, it probably means the file was corrupted during download. In that case, try downloading again.

On SPARC:
chmod +x j2re-1_3_1_<version number>-solsparc.sh

On x86:
chmod +x j2re-1_3_1_<version number>-solx86.sh

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

4. Run the self-extracting binary.

A directory called j2re1_3_1_<version number> will be created in the current directory. After the installation is finished, this directory can be renamed as desired.

Java Plug-in Product Installation Instructions

For documentation on the Java Plug-in product, see

http://java.sun.com/products/plugin/1.3.1/index.html

1. 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/

 

1. The location of the Plug-in (javaplugin.so) should be give with an absolute path—not relative to the installation location of the JRE. 2. Setting NPX_PLUGIN_PATH will override the default search path used by the browser. Therefore any plugin directories that the browser currently searches for plugins should also be added to the path.

2. 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 J2SDK 1.3.1, 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 .

3. For all Netscape browsers: Start your Netscape browser, or restart it if it is already up.

4. For Netscape 4.x browsers: Restart your browser a second time.

Restarting the browser a second time is necessary because of bug 4358142.
