Installing a 64-bit J2SE Runtime Environment (JRE) is a two-step process.

1. First, install the 32-bit J2SE Runtime Environment. Refer to the 32-bit Java Runtime Environment Installation Instructions .
2. Second, install the supplemental files for 64-bit support using the following installation instructions.

Installation Instructions

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

      <version>

For example, if you are downloading update 1.5.0_01, the following command:

      chmod +x jre-1_5_0_<version>-solaris-sparcv9.sh

would become:

      chmod +x jre-1_5_0_01-solaris-sparcv9.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 JRE.

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:

chmod +x jre-1_5_0_<version>-solaris-sparcv9.sh

3. Change directory to the same directory from where you ran the self-extracting binary for the 32-bit install.

This is the directory that contains the jre1.5.0_<version> directory of the 32-bit JRE. The next step installs the JRE into the current directory.

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

./jre-1_5_0_<version>-solaris-sparcv9.sh

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

Files for support of 64-bit operation are installed at several locations within the same jre1.5.0_<version> directory where the 32-bit JRE was installed.
