Hello, SirFalcon.

Yes, it is. If Oracle states that your Java (plugin) is fine then it is.
Foolishly I activated my Java plugin and visited this page:
http://jmonkeyengine.com/demo/applet/
I had to confirm 2 dialogues similar to the one in the screenshot below asking whether I wanted to allow a Java applet to run. I confirmed by clicking the [RUN] button twice.
(Double foolish, because Java warned me that the certificates were expired and could not be verified as being genuine.)
And then all I got was the initial page telling me something about OpenGL 2.0 being required and that the applet should work. But it did not run.
I guess your second assumption may be right. Some problem with the graphics driver software.
You are using an ATI card, me, I am using NVidia and proprietary Nvidia drivers.
Code: Select all
$ inxi -Gx
Graphics: Card: NVIDIA ION VGA bus-ID: 03:00.0
X.Org: 1.11.3 drivers: nvidia (unloaded: fbdev,vesa,nouveau) Resolution: 1280x1024@60.0hz
GLX Renderer: ION/integrated/SSE2 GLX Version: 3.3.0 NVIDIA 304.88 Direct Rendering: Yes
Looks as if this might not be good enough. But maybe, too, by blaming our graphics drivers we are on the totally wrong track now?
Before we start fiddling around with our graphics drivers - which I definitely will not do - we might take into consideration that the webpage / the applet does not really co-operate with Java 1.7.0_21? - As soon as I have got the chance I will try with Java 1.6.0_45, which has been installed on a different machine and which is needed there for some software that does not run on Java 1.7.0_21.

No, Intel graphics card plus Java 1.6.0_45 does not seem to be right, either.
Hm, I suspect the OpenGL version which we will find on Ubuntu 12.04.2/Mint 13 is not up-to-date enough, correct?
Code: Select all
glxinfo | grep "OpenGL version"
OpenGL version string: 1.4 Mesa 8.0.4his might explain why the Java applet will not display anything.
1.4 < 2.0. And this indeed brings us back to the graphics driver software.
</Added 18:00>
So final verdict for the moment:
It is not a Java problem, but a question of your OpenGL version. So, please, run the commandline
If the version string is anything lower than 2.0, you have identified the root cause why the Java applet refuses to run.
Kind regards,
Karl
