Native JAR Files

See Native JAR Files explained.

Native JAR files are loaded automatically.

Applet / JNLP Usage

A short copy is included in the static page JOGL Deployment for traditional Applets.

Custom Bundling

Fat-Jar

Discouraged Fat-Jar

I discourage this configuration, since such deployment removes our artifacts as stored in the jar's manifest file, which helps identifying the jogamp modules for bug reports etc.

Further more, adding all native library files for all supported platforms will add-up to +3M of _compressed_ jar data!

However, since we don't want to patronize our user base, we support this feature with our native JAR lib loading mechanism.

Eclipse

Native JAR files and their respective base JAR files can be bundled in custom ways, e.g. eclipse Jar-In-Jar etc.

   Manual tested w/ Eclipse:
   
   Preparations:
   ===============
   
   1) Set up a vanilla eclipse (3.7.0) workspace
   
   2) Add the JOGL User Library:
     - Window.Preference
      - Java.Build_Path.User_Libraries:
        + JOGL
           + gluegen-rt.jar
           + jogl-all.jar
           + gluegen-rt-natives-linux-amd64.jar
           + jogl-all-natives-linux-amd64.jar
   
           You may add all other native JARs here.
           Note that these are not required in the CLASSPATH by JOGL,
           however, they are required by Eclipse to export your project as a Runnable JAR File.
   3) New test project
     -  Right-click your project in the Package Explorer and click "Properties".
          - Select "Java Build Path" and click the "Libraries" tab.
             + JOGL
     - Add some simple code ..
     - Run as Java Application ..
   
   Test-1:
   =========
   
   Export
     - Right-click your project in the Package Explorer and click "Export"
       - Select Java.Runnable_JAR_file
         + Launch configuration
         + some destination path
         + Library handling:
           Copy required libraries into a sub-folder next to the generated JAR
   
   Result: Works!
   
   ./lala01.jar
   ./lala01_lib/jogl-all.jar
   ./lala01_lib/jogl-all-natives-linux-amd64.jar
   ./lala01_lib/... etc ..
   
   Test-2:
   =========
   
   Export
     - Right-click your project in the Package Explorer and click "Export"
       - Select Java.Runnable_JAR_file
         + Launch configuration
         + some destination path
         + Library handling:
           Package required libraries into generated JAR
   Result: Works!
   
   ./lala02.jar:
     Manifest-Version: 1.0
     Rsrc-Class-Path: ./ gluegen-rt-natives-linux-amd64.jar gluegen-rt.jar
                         jogl-all-natives-linux-amd64.jar jogl-all.jar
     Class-Path: .
     Rsrc-Main-Class: Test01
     Main-Class: org.eclipse.jdt.internal.jarinjarloader.JarRsrcLoader
