I'm having some wierd problems with opengl applets online too? running in a browser works perfectly when running it locally off my hard drive but as soon as I try running it on a remote server (exact same files) I get these errors listed in the java console:

opengl applets require java 1.4 to be installed, your browser might be using java 1.3 and causing the error.

Hi Ben,

I have made an opengl test app and uploaded here:
http://www.atomless.com/openglapplettester/applet/
it's simple as poss just with a class extending PApplet and the draw method sets the backround colour randomly.

I get the same error with this applet as with the applet I'm currently working on and both work perfectly locally in the same browser(firefox).

here is the java console output:

that looks like you've installed an incompatible version of jogl somewhere on your machine.

thanks ben.

ok, I feared as much. So, if I uninstall my current java install and re-install the latest java from sun that should fix things right??

actually that looks more like things are corrupt with the files on the server. perhaps your ftp/sftp client is screwing things up? like not sending some of the files as binary or some files as incomplete?

I tried the OpenGL applet for the first time and got an error that said it was Unable to load libjogl.jnilib.

So, i tracked down a copy and added it to the applet folder, no luck.  Wondering what I did wrong.

-robert

Oh, Mac OSX 10.4.6, Java 1.4.2_09, exported out of Processing 115, and implemented the processingHacks changes to the html doc.

UPDATE ------------------------------
Oops, its an intel mac issue.  Works fine on my slightly older mac laptop.

I'm getting some strange errors from an OpenGL applet I've created & was wondering if anyone had similar experience and/or insight. While it runs fine on some machines/JVMs, it won't load at all on other, throwing the following Exception (the below from OSX, Java1.5)..
thanks much -dc

i think there may be issues with the opengl stuff and intel macs in the most recent releases.. i think it'll be ironed out for 0116.

Exported an OpenGL applet with 0117 and get this error when I try to run it in the browser:

Code:

java.security.AccessControlException: access denied (java.util.PropertyPermission user.home read)
at java.security.AccessControlContext.checkPermission(Unknown Source)
at java.security.AccessController.checkPermission(Unknown Source)
at java.lang.SecurityManager.checkPermission(Unknown Source)

at com.sun.opengl.util.JOGLAppletLauncher.start(JOGLAppletLauncher.java:288)
at sun.applet.AppletPanel.run(Unknown Source)
at java.lang.Thread.run(Unknown Source)


Just looks like something isn't signed.

Also, the exporter looks for jogl-natives-linux.jar, rather than jogl-natives-linux-i586.jar, which is what the file is actually named. Renaming it fixed this problem, of course.

that looks like two things

1) is there a nightly build of the jogl code somewhere in your sketchbook or libraries directories? this would cause the error for the thing not being signed. did the security dialog come up saying "do you trust this code from sun?"

2) it looks like it's also an *older* version of jogl than what's shipped with processing 0117, because the naming for the jar files has changed with the more recent releases of jogl.

i'm not sure whether these are something wrong on your end or ours, but check on that stuff first.


edit: scratch that.. the version of jogl.jar that's included with 0117 is the wrong file. it's not signed, and may even be an earlier version. damn, that's annoying, i dunno how it was the wrong file. until the next release, you can download this file:

http://download.java.net/media/jogl/builds/archive/jsr-231-1.0.0/jogl-1_0_0-webstart.zip

and copy the jogl.jar from inside that .zip to opengl/library/jogl.jar. when you export, it'll work properly again.

I checked the naming in 0115 for the linux native and it does not have i568 in it. The version that is included with 0116 does, however.

Also, thank you for being so amazingly prompt in responding to this.
