This chapter covers setting up of the environment to use JOGL on your system
using different Integrated Development Environments (IDEs).
You need to follow the given steps to setup your environment to start with JOGL
application development −
Verify the output on the respective operating system.
Set Java-home environment variable to point to the base directory location on the same path, where Java is installed on your machine.
Append Java compiler location to System Path as follows −
This takes you to the list of .jar files for all APIs maintained by the website.
Get the source codes gluegen-java-src.zip and jogl-java-src.zip for supporting IDE. This is optional.
Step 2 − Create a new project.

Installing JOGL
For JOGL Installation, you need to have following system requirements −System Requirements
The first requirement is to have the Java Development Kit (JDK) installed on your machine.| Requirement | Description |
|---|---|
| JDK Version | 1.4 or above |
| Memory | no minimum requirement |
| Disk Space | no minimum requirement |
| Operating System | no minimum requirement |
Step 1 - Verifying Java Installation on Your Machine
Open console of your system and execute the following java command −| Platform | TASK | COMMAND |
|---|---|---|
| Windows | Open Command Console | C:\>java-version |
| Linux | Open Command terminal | $java- version |
| MAC | Open Terminal | Machine:~ joseph$ java -version |
| Platform | Output |
|---|---|
| Windows | Java “1.6.0.21” java(TM) SE Runtime Environment(build 1..6.0_21-b07)Java HotSpot(TM) Client VM(build 17.0-b7, mixed mode, sharing) |
| Linux | Java “1.6.0.21” java(TM) SE Runtime Environment(build 1..6.0_21-b07)Java HotSpot(TM) Client VM(build 17.0-b7, mixed mode, sharing) |
| MAC | Java “1.6.0.21” java(TM) SE Runtime Environment(build 1..6.0_21-b07)Java HotSpot(TM) Client VM(build 17.0-b7, mixed mode, sharing) |
Step 2 – Setting up Java Development Kit (JDK)
If Java is not installed on your machine, then you need to install Java SDK from the Oracle website: Oracle. You can find instructions for installing the JDK from the downloaded files. You need to follow the given instructions to install and configure the setup. Finally, set PATH and JAVA_HOME environment variables to refer to the directory that contains java.exe and javac.exe files, typically java_install_dir/bin and java_install_dir respectively.Set Java-home environment variable to point to the base directory location on the same path, where Java is installed on your machine.
| Platform | Command |
|---|---|
| Windows | Set the environment variable JAVA_HOME to C:\ProgramFiles\Java\Jdk1.6.0_21 |
| Linux | Export JAVA_HOME=/usr/local/java-current |
| MAC | Export JAVA_HOME=/Library/Java/Home |
| Platform | Command |
|---|---|
| Windows | Append the string ;%JAVA_HOME% bin at the end of the system variable and path |
| Linux | Export PATH=$PATH:$JAVA_HOME/bin/ |
| MAC | Not required |
Step 3 – Downloading JOGL
- You can download latest version of JOGL from the website www.jogamp.org
- Go to the home page of www.jogamp.org
- Click on Builds/Downloads > Current (zip).
This takes you to the list of .jar files for all APIs maintained by the website.
- Download the library .jar file jogamp-all-platforms.7z, java documentations for OpenGL native library glugen-javadoc.7z, and JOGL jogl-javadocs.7z.
- Extract the downloaded .jar files using any zip extracting software.
Get the source codes gluegen-java-src.zip and jogl-java-src.zip for supporting IDE. This is optional.- Inside the jar folder, there are multiple .jar files. This collection of files belongs to Glugen and JOGL.
- JOAMP provides native libraries that support various operating
systems such as Windows, Solaris, Linux and Android. Hence, you need to
take appropriate jar files which can execute on your desired platform.
For example, if you are using Windows 64-bit operating system, then get
the following .jar files from the jar folder −
- gluegenrt.jar
- jogl-all.jar
- gluegen-rt-natives-windows-amd64.jar
- jogl-all-natives-windowsamd64.jar
