Java Advanced Imaging ImageIO Tools
This article captures current information about the Java Advanced Imaging ImageIO Tools to document exactly what files are involved.
The ImageIO Tools consist of two jar files plus one or more files which are in native code for the platform. The names in the tables below are the ones that appeared in versions 1.0 and 1.1. As the ImageIO Tools progress, the names of the files may accumulate release identification, as in jai_imageio-1.2-pre-dr-b04.jar.
1 JAR Files

|---|---|---|
| jai_imageio.jar | JAR file containing core JAI Image I/O class files | jre/lib/ext |

3 Installation Files
The Oracle site no longer provides links to the ImageIO Tools version 1.1 or later. The files necessary to install the tools on several platforms have been put on the RSNA MIRC site.
3.1 Windows
The Windows installer for the ImageIO Tools is available at: jai_imageio-1_1-lib-windows-i586-jre.exe
A zip file containing the files (not required if using the installer) is available at: http://mirc.rsna.org/ImageIO/win-i686.zip
3.2 Linux
A zip file for installing the ImageIO Tools on an i686 platform is available at: http://mirc.rsna.org/ImageIO/linux-i686.zip
A zip file for installing the ImageIO Tools on an x86_64 platform is available at: http://mirc.rsna.org/ImageIO/linux-x86_64.zip
3.3 Solaris
A zip file for installing the ImageIO Tools on an i686 platform is available at: http://mirc.rsna.org/ImageIO/solaris-i686.zip
A zip file for installing the ImageIO Tools on a SPARC platform is available at: http://mirc.rsna.org/ImageIO/solaris-sparc.zip
A zip file for installing the ImageIO Tools on a SPARC v9 platform is available at: http://mirc.rsna.org/ImageIO/solaris-sparcv9.zip
A zip file for installing the ImageIO Tools on an x86_64 platform is available at: http://mirc.rsna.org/ImageIO/solaris-x86_64.zip
3.4 Macintosh
A zip file containing the two jar files is available at http://mirc.rsna.org/ImageIO/ImageIOJars.zip.
No native libraries are available for the Macintosh. Place the two jar files into:
- /Library/Java/JavaVirtualMachines/jdk.../lib/ext.
4 Notes
- The jar files are required.
- The dll/so files are optional.
- The dll/so files provide acceleration for certain image types.
- The dll/so files may also provide support for additional image types.
- You can force the ImageIO Tools not to use the native libraries by starting a program with this switch:
- -Dcom.sun.media.imageio.disableCodecLib=true
