jogl 2.0 build 270 GLException

Up until today I've been using the following piece of code with build 223 with no problems...

                try {
                        floorTexture = TextureIO.newTexture(new File(filename), false);
                        floorTexture.setTexParameteri(GL.GL_TEXTURE_MIN_FILTER, GL.GL_LINEAR);
                        floorTexture.setTexParameteri(GL.GL_TEXTURE_MAG_FILTER, GL.GL_LINEAR);
                } catch (IOException e) {
                        System.err.println("Error loading " + filename);
                }

I switched today to the latest autobuild, 270, and I'm now getting no texture showing up (it's all white).  When I turn on GL debugging, I see this error:

glGetError() returned the following error codes after a call to glTexImage2D(<int> 0xDE1, <int> 0x0, <int> 0x1907, <int> 0x2D0, <int> 0x2D0, <int> 0x0, <int> 0x80E0, <int> 0x1401, <java.nio.Buffer>): GL_INVALID_VALUE ( 1281 0x501),

And, when I turn on the trace, it shows me:

glTexImage2D(<int> 0xDE1, <int> 0x0, <int> 0x1907, <int> 0x2D0, <int> 0x2D0, <int> 0x0, <int> 0x80E0, <int> 0x1401, <java.nio.Buffer> null)Exception in thread "AWT-EventQueue-0-AWTAnimator-1" javax.media.opengl.GLException: javax.media.opengl.GLException: Thread[AWT-EventQueue-0,6,main] glGetError() returned the following error codes after a call to glTexImage2D(<int> 0xDE1, <int> 0x0, <int> 0x1907, <int> 0x2D0, <int> 0x2D0, <int> 0x0, <int> 0x80E0, <int> 0x1401, <java.nio.Buffer>): GL_INVALID_VALUE ( 1281 0x501),

This seems like it could be related to not setting GL_TEXTURE_MIN_FILTER to GL_LINEAR, but I have that.

Sorry, I know there's a better way to include code snippets, but I don't know how.

Any ideas?

Thanks,

I'll try creating a test case for this tomorrow. I've already got another one that I can base it on.

I set up a quick unit test for this, and it seems to work fine. I'm running against the latest build on CentOS 5.4. Here's the code (Just substitute the filename of your texture in there):

    public static void main(String args[]) throws IOException {

I've confirmed this also works on Windows XP with the latest JOGL.

Thanks Wade.

I have the same issue with your test.  The texture doesn't show up (well, it's all white) and when I turn on the GLDebugging i get that same error.

I'm on a Windows 7, 64-bit box with a Radeon 5770 grahics card.

I'm going to verify that I have the most up to date drivers and I'll get back with yall.

Thanks,

bcothren

Ok, so I upgraded to the latest drivers for my card and all is well.

Sorry to have wasted your time, Wade.  Thanks for the help.

bcothren

No problem -- I needed to develop a better texture test anyway  I'm sure I'll reuse that code in another unit test soon.

Just let us know if you have any more problems!
