Dear community,
I'm sorry, I have to contact you again with a problem that seems to be quite simple.
A few years ago, I had difficulties getting started with JOGL (in that time version 1.1). Today (with version 2.1) the problem has recurred. I'm trying to compile and run a simple demo, which came along with "Tutorial on JOGL 2.1
Including Nehe JOGL Port", URL: https://www3.ntu.edu.sg/home/ehchua/programming/opengl/JOGL2.0.html. The program is named "JOGL2Setup_GLCanvas".
Setting up the JOGL environment with CLASSPATH and PATH, as well as the compiling worked fine, but at runtime it comes out that apparently the creation of GLCanvas is not successful. It results in null, whatever I experiment with GLProfile and/or GLCapabilities.
Could you help me with a basic sample demo, which does nothing but presenting a red square on the screen or something like that?
Many thanks in advance!
