Download Instructions

Using your browser, download the appropriate executable(s) or tar.gz files from the download page to the location where you want to temporarily store them. 

Installation Instructions

• Solaris 32-bit Operating Environment Installation Instructions

For the SPARC edition, the download files are: 

• jai-1_1_3-lib-solaris-sparc-jdk.bin
• jai-1_1_3-lib-solaris-sparc-jre.bin
• jai-1_1_3-lib-solaris-sparc.tar.gz
For the Intel edition, they are: 
• jai-1_1_3-lib-solaris-i586-jdk.bin
• jai-1_1_3-lib-solaris-i586-jre.bin
• jai-1_1_3-lib-solaris-i586.tar.gz
Assuming:

$JDK       is the path into the jdk1.3 (or a higher version),
$downloaddir  is the directory into which you downloaded the .bin files.

To install the JDK version for Solaris:
• If you are on a SPARC-based system, run the commands:

% cd $JDK
% chmod u+x $downloaddir/jai-1_1_3-lib-solaris-sparc-jdk.bin
% $downloaddir/jai-1_1_3-lib-solaris-sparc-jdk.bin

• If you are on an Intel-based system, run the commands:

% cd $JDK
% chmod u+x $downloaddir/jai-1_1_3-lib-solaris-i586-jdk.bin
% $downloaddir/jai-1_1_3-lib-solaris-i586-jdk.bin

You may answer 'yes' to any questions about replacing files. You may delete the jai-1_1_3-*.bin files after you are done with the extraction.

IMPORTANT: If you do not "cd" to the JDK1.3 (or higher version) directory before performing the extraction, then JAI will not work correctly. You may also need appropriate write permissions into the JDK directory in order to install.

To install the JRE version for Solaris: 

      % cd $JRE         ($JRE is the path into jre1.3 or later version.)

• If you are on a SPARC-based system, run the commands:

% chmod u+x $downloaddir/jai-1_1_3-lib-solaris-sparc-jre.bin
% $downloaddir/jai-1_1_3-lib-solaris-sparc-jre.bin

• If you are on an Intel-based system, run the commands:

% chmod u+x $downloaddir/jai-1_1_3-lib-solaris-i586-jre.bin
% $downloaddir/jai-1_1_3-lib-solaris-i586-jre.bin

To view an html page containing an (JAI or other optional package) applet, the Java Plug-in must also be registered with the browser as described at http://java.sun.com/j2se/1.4.2/install-solaris.html#plugin.  

IMPORTANT: If you do not "cd" to the JRE1.3 (or higher version) directory before performing the extraction, then JAI will not work correctly. You may also need appropriate write permissions into the JRE directory in order to install. 

• Solaris 64-bit Operating Environment Installation Instructions

For the SPARC edition, the download files are: 

• jai-1_1_3-lib-solaris-sparcv9-jdk.bin
• jai-1_1_3-lib-solaris-sparcv9-jre.bin
• jai-1_1_3-lib-solaris-sparcv9.tar.gz
For the AMD64 edition, they are:

• jai-1_1_3-lib-solaris-amd64-jre.bin
• jai-1_1_3-lib-solaris-amd64.tar.gz
Assuming:

$JDK       is the path into the jdk1.3 (or a higher version),
$downloaddir  is the directory into which you downloaded the .bin files.

To install the JDK version for Solaris:
• First install the 32-bit version for JDK as described above.
• If you are on a SPARC-based system, run the commands:

% cd $JDK
% chmod u+x $downloaddir/jai-1_1_3-lib-solaris-sparcv9-jdk.bin
% $downloaddir/jai-1_1_3-lib-solaris-sparcv9-jdk.bin

• If you are on an AMD-based system, run the commands:

% cd $JDK
% chmod u+x $downloaddir/jai-1_1_3-lib-solaris-amd64-jdk.bin
% $downloaddir/jai-1_1_3-lib-solaris-amd64-jdk.bin

You may answer 'yes' to any questions about replacing files. You may delete the jai-1_1_3-*.bin files after you are done with the extraction.

IMPORTANT: If you do not "cd" to the JDK1.3 (or higher version) directory before performing the extraction, then JAI will not work correctly. You may also need appropriate write permissions into the JDK directory in order to install.

To install the JRE version for Solaris: 

      % cd $JRE         ($JRE is the path into jre1.3 or later version.)

• First install the 32-bit version for JRE as described above.
• If you are on a SPARC-based system, run the commands:

% chmod u+x $downloaddir/jai-1_1_3-lib-solaris-sparcv9-jre.bin
% $downloaddir/jai-1_1_3-lib-solaris-sparcv9-jre.bin

• If you are on an AMD-based system, run the commands:

% chmod u+x $downloaddir/jai-1_1_3-lib-solaris-amd64-jre.bin
% $downloaddir/jai-1_1_3-lib-solaris-amd64-jre.bin

To view an html page containing an (JAI or other optional package) applet, the Java Plug-in must also be registered with the browser as described at http://java.sun.com/j2se/1.4.2/install-solaris.html#plugin.  

IMPORTANT: If you do not "cd" to the JRE1.3 (or higher version) directory before performing the extraction, then JAI will not work correctly. You may also need appropriate write permissions into the JRE directory in order to install. 

• CLASSPATH Installation Instructions for Solaris/Linux Platforms

The tar.gz downloads are installations which do not check for the JDK or the JRE and install into a directory called jai-1_1_3 by default. CLASSPATH needs to be set to point to the jar files in this directory. 

Assuming:

$PLATFORM   is the specific platform (solaris-sparc/solaris-i586/linux-i586/linux-amd64)

$JAIDIR is the directory into which the JAI files are to be installed
To install, change directories to $JAIDIR, unzip, untar, and set CLASSPATH as follows:

% cd $JAIDIR
% gunzip -c $downloaddir/jai-1_1_3-lib-($PLATFORM).tar.gz | tar xf -

Set CLASSPATH as follows: 

% setenv JAIHOME $JAIDIR/jai-1_1_3/lib
% setenv CLASSPATH $JAIHOME/jai_core.jar:$JAIHOME/jai_codec.jar:$JAIHOME/mlibwrapper_jai.jar:$CLASSPATH
% setenv LD_LIBRARY_PATH .:$JAIHOME:$CLASSPATH

Unlike for the JRE and JDK installations, the 64-bit version Solaris platform bundles for CLASSPATH installation, jai-1_1_3-lib-sparcv9.tar.gz and jai-1_1_3-lib-amd64.tar.gz, are self-contained and will function in 64-bit mode only. If they are unpacked in the same location as the equivalent 32-bit bundle they will overwrite the files extracted from the 32-bit bundle.
• Microsoft Windows Operating Environment Installation Instructions

The downloaded objects are executable files. In Microsoft Windows, they are .exe files: 

• jai-1_1_3-lib-windows-i586.exe
• jai-1_1_3-lib-windows-i586-jre.exe
• jai-1_1_3-lib-windows-i586-jdk.exe
To install the library files, double-click on the jai-1_1_3-lib-windows-i586.exe icon and follow the directions. This will install the library files into a default location

C:\Program Files\Sun Microsystems\Java Advanced Imaging 1.1.3

without any check for the JDK or the JRE 

To install the JRE version, double-click on the jai-1_1_3-lib-windows-i586-jre.exe icon and follow the directions. 

To install the JDK version, double-click on the jai-1_1_3-lib-windows-i586-jdk.exe icon and follow the directions. 

You may delete the jai-1_1_3-*.exe files after you are done with the extraction. 

IMPORTANT: The executable will try to install JAI within the latest JDK (or JRE) version that it finds. If you need to install and use JAI within another JDK (or JRE) version on disk, please make sure you enter a valid JDK directory when prompted. 

• Linux 32- and 64-bit Operating Environment Installation Instructions

The downloaded files are: 

• jai-1_1_3-lib-linux-$ARCH-jdk.bin
• jai-1_1_3-lib-linux-$ARCH-jre.bin
• jai-1_1_3-lib-linux-$ARCH.tar.gz
where ARCH is either i586 for the 32-bit platform or amd64 for the 64-bit platform.

To install the JDK version for Linux, assuming: 

$JDK       is the path into the jdk1.3 (or a higher version),
$downloaddir  is the directory into which you downloaded the .bin files.

Run the following commands:

% cd $JDK
% chmod u+x $downloaddir/jai-1_1_3-lib-linux-$ARCH-jdk.bin
% $downloaddir/jai-1_1_3-lib-linux-$ARCH-jdk.bin

Note that unlike in the case of Solaris, the Linux 32- and 64-bit installations are not layered but rather mutually exclusive.

IMPORTANT: If you do not "cd" to the JDK1.3 (or higher version) directory before performing the extraction, then JAI will not work correctly. You may also need appropriate write permissions into the JDK directory in order to install. 

To install the JRE version for Linux, try 

      % cd $JRE         ($JRE is the path into jre1.3 or later version.)
      % chmod u+x $downloaddir/jai-1_1_3-lib-linux-$ARCH-jre.bin
      % $downloaddir/jai-1_1_3-lib-linux-$ARCH-jre.bin

IMPORTANT: If you do not "cd" to the JRE1.3 (or higher version) directory before performing the extraction, then JAI will not work correctly. You may also need appropriate write permissions into the JRE directory in order to install. 
• Java Platform-Independent Installation Instructions

The downloaded file is: 

• jai-1_1_3-lib.zip

Unpacking the archive will create a directory (folder) named jai-1_1_3 which contains the LICENSE-jai.txt and other legal files at the top level and a lib subdirectory containing jai_core.jar and jai_codec.jar. To install the Java version simply unpack the archive and set the CLASSPATH environment variable to include jai_core.jar and jai_codec.jar. If only the codec packages com.sun.media.jai.codec are desired then jai_core.jar may be omitted from the CLASSPATH. For additional information refer also to the section Running Without Native Acceleration.

• Automatic Installation of JAI

Java^TM Plug-in Technology establishes a connection between popular browsers and the Java^TM platform. The Java^TM Plug-in 1.4.2. Developer Guide discusses how to use the Java^TM Plug-in Component to enable applets in browsers. One of the capabilities provided by Java^TM Plug-in (JPI) is Java^TM extension deployment. The JPI installs or replaces the Java extensions (such as JAI) in your browser with an updated version. If a user's browser runs a Java program requiring an Optional Package, the JPI can be made to automatically download and run the Optional Package's installer. For more information please refer to the detailed instructions on how to deploy an applet which may deploy an Optional Package such as JAI.

A JPI auto-installation download bundle for JAI is provided for each of the supported platforms:

Platform	Download Bundle	Contents
solaris-sparc	jai-1_1_3-solaris-sparc-jar.zip	jai_solaris-sparc.jar
solaris-sparcv9	jai-1_1_3-solaris-sparcv9-jar.zip	jai_solaris-sparcv9.jar
solaris-amd64	jai-1_1_3-solaris-amd64-jar.zip	jai_solaris-amd64.jar
solaris-i586	jai-1_1_3-solaris-i586-jar.zip	jai_solaris-i586.jar
linux-amd64	jai-1_1_3-linux-amd64-jar.zip	jai_linux-amd64.jar
linux-i586	jai-1_1_3-linux-i586-jar.zip	jai_linux-i586.jar
windows-i586	jai-1_1_3-windows-i586-jar.zip	jai_windows-i586.jar

Each bundle is a Zip archive containing a signed JAI extension jar file which in turn contains a JAI JRE installer. The Implementation-URL attribute of the manifest of the applet jar file must refer to this signed jar file. Thus developers of applets which use auto-installation of JAI must unpack the Zip archive and place the jar file contained therein at the location specified by the Implementation-URL attribute of their applet jar file's Manifest. For example, the applet jar file's manifest might look like this

Extension-List: jai_core
jai_core-Extension-Name: javax.media.jai
jai_core-Specification-Version: 1.1-mr
jai_core-Implementation-Version: 1.1.3
jai_core-Implementation-Vendor-Id: com.sun
jai_core-Implementation-URL: http://mydomain.com/jai_solaris-sparc.jar

if the solaris-sparc auto-installation jar file was being used and was located at the top level of the http://mydomain.com server.

As with the standard Solaris 64-bit JRE installation, the 64-bit automatic installation on solaris-sparcv9 and solaris-amd64 is layered over the respective 32-bit automatic installation. For automatic installation this means that the applet's manifest jar file must include both installers for example as

Extension-List: jai_core jai_core64
jai_core-Extension-Name: javax.media.jai
jai_core-Specification-Version: 1.1-mr
jai_core-Implementation-Version: 1.1.3
jai_core-Implementation-Vendor-Id: com.sun
jai_core-Implementation-URL: http://mydomain.com/jai_solaris-sparc.jar
jai_core64-Extension-Name: javax.media.jai64
jai_core64-Specification-Version: 1.1-mr
jai_core64-Implementation-Version: 1.1.3
jai_core64-Implementation-Vendor-Id: com.sun
jai_core64-Implementation-URL: http://mydomain.com/jai_solaris-sparcv9.jar

Note that the version of the JPI specified by an applet must match the version of JPI installed in the browser. Note also that installation will not succeed if the user does not have write permission for the JPI installation location. See also (Updating CLASSPATH, PATH, and LD_LIBRARY_PATH) for information related to the usage of the correct version of JPI.

Read the top-level JAI README file for information on what is in this release of Java Advanced Imaging. 

Updating CLASSPATH, PATH, and LD_LIBRARY_PATH

If JAI is installed as part of the Java 2 SDK's Java Runtime Environment, no CLASSPATH or LD_LIBRARY_PATH settings are required. When you encounter problems running JAI applications, it is most likely that you are not running the correct version of java (jdk). Check with the command "java -version" on Solaris or at Dos prompt. If needed, set the PATH correctly to use the correct version of JDK or JRE as follows. 

For Solaris: 

% setenv PATH $JDK/bin:$PATH;    or
% setenv PATH $JRE/bin:$PATH

The Java Plug-in must also be registered with the browser as described at http://java.sun.com/j2se/1.4.2/install-solaris.html#plugin. Note: The plugin used should be v1.3.1 or higher 

For Windows: 

A point to be noted on the Windows platform is that the Java2 SDK 1.3, by default, installs Java into both the JDK location: 

c:\jdk1.3

and into the JRE location: 

C:\Program Files\JavaSoft\jre\1.3

Additionally, a shortcut to java.exe is installed in the WINNT/System32 (for NT systems) or Windows/System (for Windows 95 and 98) directory. 

Developers need to be aware of this when working with the Java 2 SDK. Unless the path to the 1.3 SDK jre\bin and bin directories is placed in the PATH environment variable in the same order, ahead of the system directory, the SDK's java.exe will not be executed. Any extensions (such as JAI) that are installed into the SDK but not into the JRE will not be found during program execution. The same applies to higher versions of the JDK. 

To set PATH environment variable, you may need to edit autoexec.bat on Windows 98/95. For other Windows systems, try click Start-Settings-ControlPanel, then double click on System. Choose Environment. Under System Variables, click on Path, and update its value to put

  c:\Program Files\JavaSoft\jre\1.3\bin;     or
  c:\jdk1.3\jre\bin;     or 
  c:\jdk1.3\bin;

ahead of others. Note that ";" is used to separate from other values. To double check, open a DOS command prompt and use "set" or "set path" to view the PATH environment variable.

If you have used the CLASSPATH install into arbitrary location for Windows, then you will also need to set your CLASSPATH variable to point to each of the jai jar files in your installed directory 

Running Without Native Acceleration

JAI can be run without its native acceleration layer without loss of functionality. This may be accomplished either by using the Java Platform-Independent Version or by setting the system property com.sun.media.jai.disableMediaLib to true. Note that when running without the native layer unless the aforementioned property is set to true warning messages will be emitted to indicate the inability to load the native wrapper or libraries.

Uninstall Instructions

• Solaris/Linux Operating Environment

% cd $JDK

where $JDK is the path into the jdk1.3 (or a higher version) directory, where JAI was installed.

% chmod u+x UNINSTALL-jai
% ./UNINSTALL-jai

• Microsoft Windows Operating Environment
You would need to go to the Control Panel and double-click on Add/Remove Programs. Find the listing for Java Advanced Imaging 1.1.3 and click on Add/Remove. This should uninstall the library for you.

Permission-Related Issues

• Run Applets with MediaLib-Enabled
 
On the Solaris platform, the following permission has to be added in the file java.policy located at $JRE/lib/security:

permission java.io.FilePermission "/usr/bin/uname", "execute";

For the other platforms, the mediaLib version is enabled by default .

• File Permission for Decoding in Applets
 
When FileCacheSeekableStream is used, either explicitly or implicitly, the permissions for the default temporary-file directory (defined by the system property "java.io.tmpdir") are necessary.  That is, add the following line into the proper policy file:

permission java.io.FilePermission ${java.io.tmpdir}/*, "read,write,delete";
