Hello! Everyone is welcome, English native or not
Our tutorials are listed at
https://jogamp.org/wiki/index.php/Jogl_Tutorial. If you use Eclipse especially, there are lots of examples. Some of these are also on my blog at
http://wadeawalker.wordpress.com/.
There's also a page on our wiki at
https://jogamp.org/wiki/index.php/Setting_up_an_Eclipse_project_that_uses_JOGL that tells how to download JOGL and set up an Eclipse project that uses it.
If you have any questions about these tutorials, or you have suggestions for new ones, just post here -- someone in the community can probably help.
It might help if you told us more about your project. Are you making a desktop application or a web application? What will the project do? Does it have to run cross-platform, or is it one platform only?
