System Requirements:
JavaTM 2 SDK 1.3.1 for Linux Installation Notes for more information on JVM system requirements for Linux. Download InstructionsUsing 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. The download has been broken into two archives for convenience. The first archive contains the JAI library itself and is required in order to run JAI. The second archive contains sample code and images that may optionally be downloaded in order to demonstrate some of the functionality of JAI. Installation Instructions
For the SPARC edition, the download files are: $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:
% cd $JDK % chmod u+x $downloaddir/jai-1_1_2_01-lib-solaris-sparc-jdk.bin % $downloaddir/jai-1_1_2_01-lib-solaris-sparc-jdk.bin % cd $JDK % chmod u+x $downloaddir/jai-1_1_2_01-lib-solaris-i586-jdk.bin % $downloaddir/jai-1_1_2_01-lib-solaris-i586-jdk.binYou may answer 'yes' to any questions about replacing files. You may delete the jai-1_1_2_01-*.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.)
% chmod u+x $downloaddir/jai-1_1_2_01-lib-solaris-sparc-jre.bin % $downloaddir/jai-1_1_2_01-lib-solaris-sparc-jre.bin % chmod u+x $downloaddir/jai-1_1_2_01-lib-solaris-i586-jre.bin % $downloaddir/jai-1_1_2_01-lib-solaris-i586-jre.binTo 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.
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_2_01 by default. CLASSPATH needs to be set to point to the jar files in this directory. Assuming: $PLATFORM is the specific platform (solaris-sparc/solaris-i586/linux-i586)$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 $downloaddir/jai-1_1_2_01-lib-($PLATFORM).tar.gz | tar xf -Set CLASSPATH as follows: % setenv JAIHOME $JAIDIR/jai-1_1_2_01/lib % setenv CLASSPATH $JAIHOME/jai_core.jar:$JAIHOME/jai_codec.jar:$JAIHOME/mlibwrapper_jai.jar:$CLASSPATH % setenv LD_LIBRARY_PATH .:$JAIHOME:$CLASSPATH The downloaded objects are executable files. In Microsoft Windows, they are .exe files:
To install the JRE version, double-click on the jai-1_1_2_01-lib-windows-i586-jre.exe icon and follow the directions. To install the JDK version, double-click on the jai-1_1_2_01-lib-windows-i586-jdk.exe icon and follow the directions. You may delete the jai-1_1_2_01-*.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.
The downloaded files are:
$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_2_01-lib-linux-i586-jdk.bin % $downloaddir/jai-1_1_2_01-lib-linux-i586-jdk.binIMPORTANT: 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_2_01-lib-linux-i586-jre.bin % $downloaddir/jai-1_1_2_01-lib-linux-i586-jre.binIMPORTANT: 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.
The downloaded files are:
% gunzip -c $downloaddir/jai-1_1_2-Unix-sample.tar.gz | tar xf -On Windows: double-click on the jai-1_1_2-windows-i586-sample.exe icon and follow the directions.
JavaTM Plug-in Technology establishes a connection between popular browsers and the JavaTM platform. The JavaTM Plug-in 1.4.2. Developer Guide discusses how to use the JavaTM Plug-in Component to enable applets in browsers. One of the capabilities provided by JavaTM Plug-in (JPI) is JavaTM 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:
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: 1.1.2_01 jai_core-Implementation-Vendor-Id: com.sun jai_core-Implementation-URL: http://mydomain.com/jai_solaris-sparc.jarif the solaris-sparc auto-installation jar file was being used and was located at the top level of the http://mydomain.com server. 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. After Java Advanced Imaging is installedJava Advanced Imaging will be installed under the $JDK directory with the following files:
If the sample archive has been installed, the following files will also be installed:
Read the top-level README-jai.txt file for information on what is in this release of Java Advanced Imaging. Updating CLASSPATH, PATH, and LD_LIBRARY_PATHIf 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 $JRE/bin:$PATHThe 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:\jdk1.3and into the JRE location: C:\Program Files\JavaSoft\jre\1.3Additionally, 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 Uninstall Instructions
% cd $JDKwhere $JDK is the path into the jdk1.3 (or a higher version) directory, where JAI was installed. % chmod u+x UNINSTALL-jai % ./UNINSTALL-jai
Permission-Related Issues
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 .
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";
