Access to jogamp.org

Thanks for your answer. I'm happy to have found competent partners who are ready to take care of my problems.

Indeed I've got several problems:

First of all there is this damned difficulty to access jogamp.org, which is well known to you. Some years ago I succeeded already implementing JOGL, but I were using a publication of Jim X Chen & Chunyang Chen: Foundations of 3D Graphics Programming using JOGL and Java3D, Springer London, 2008. In this publication I found a link to http://cs.gnu.edu/-jchen/graphics/setup.html, where I could download all the Java examples in this book. All programs could be compiled and run without errors. However, this Website seems to be out-of-date today, and is also unaccessable.

My second question concerns the module Jogl.dll. Is it necessary or not? Some authors claim that it is not, and under JOGL 2 everything would be bound automatically. However, I couldn't find anything about "JOGL 2", and, moreover, omitting the module in the library path will lead surely to the message "no jogl found". Now please tell me: What's about Jogl.dll? I've got it from the examples of J Chen mentioned above, but all the libraries got from jogamp.org in earlier times did not contain any Jogl.dll (only gluegen-rt.dll, jogl-cg.dll and some others).

Finally, third, I've got problems migrating my programs to Windows 7 64 Bit. I already posted some documents to Julien Gouesse, containing the source TestJOGL.java, the error free result of the program under Windows 32 Bit, and the error output in the case of using exact the same program under Windows 64 Bit. There is some persistant error concerning class casting, and I guess that it must be a compatibility problem with the dlls.

By the way, please excuse my unprofessional style of speech. I'm a real German, and it's the first time that I'm participating in an English forum discussion.

Best regards from

Bernhard Kilger, Pulheim, Germany

You're right, it's down again. Sorry, I'm not sure of the cause. Hopefully Sven is aware.

Hallo Wide,

many thanks. I'll try the way via the link you mentioned.

But what about the general access to jogamp.org? It still doesn't run at my PC.

Best regard

Hi Bernhard,

In JOGL 2 for several years now, separate .dll files haven't been necessary. They're hidden inside gluegen-rt-natives-windows-amd64.jar and jogl-all-natives-windows-amd64.jar, and they're secretly unzipped into a temp directory somewhere on your system when you load the first JOGL class. You can see the exact JAR files I use at https://github.com/WadeWalker/com.jogamp.jogl, though these are not official releases and they may be overkill for your situation (e.g. if you don't have to deploy on all 3 desktop platforms).

I'm not sure what the difficulty is with Windows 7 64-bit. One of the disadvantages of Sven not being around much these days is that we don't have access to his test cluster, which had these older operating systems that we could test on. I only do unofficial releases for my own use, so I can only test on the latest versions of the desktop OSes and the latest Java that are installed on my own computers.

Thank you,

it would be fine if you could watch the problem and tell me when your colleague will be well and back again.

The access to JOGL is rather important for me. I'm working on a java application to simulate a chemical construction kit. The program will accept a random set of atoms and chemical bonds between them (in graphics represented by spheres and cylindrical sticks) and show the structure in a 3D stereoscopical manner. The application works already in a rudimentary version, which I like to power up to Windows 64 Bit to (possibly) achieve even better performance. This is the point where I got compatibility problems and tried to go back to the Jogl roots. Therefore, access to jogamp.org is necessary for me

Best regards

Bernhard Kilger.

I'm not sure what's going on with the site either :( I'm not in regular communication with Sven these days, unfortunately, and he set up all the infrastructure.

Hallo Wide,

many thanks once again.

But I must tell you that the difficulties go on. I have established all your jar's in the CLASSPATH, but trying to compile my TestJOGL.java leads to an error message concerning the central class GL:

error: cannot access GL
bad class file: d:\jogl\jogl-all.jar(com/jogamp/opengl/GL.class)
class file has wrong version 55.0, should be 52.0
Please remove or make sure it appears in the correct subdirectory of the classpath

The class GL seems to be found but to have the wrong "version". I don't know how to handle this message.

And once again: What's about the general access to jogamp.org? It still doesn't run at my PC.

Best regard

Bernhard

But it was a lot of work, because half the references to the OpenGL classes didn't match any more (for example GL2 instead of GL, and so on). It was a rather desperate work, like poking in a haystack! But now I'm ready again using Windows 64 Bit.

On the other hand, I have got the equivalent problem trying the same on my second PC, here working with 32 Bit Windows. It seems to be impossible to establish the right JOGL libraries and jar's. The compiler runs without errors, but the execution leads to ClassLoader problems, for instance concerning WriteClonable in the display section, among others.
It would be nice, if I could get a reliable step by step instruction to run the correct binding of JOGL, based an the actual Java version 8.211.
