Hi everybody,
here is my problem :
I try to use some Jogl code in an Eclipse RCP project (Eclipse 3.1), but I
have the following error message :
Unhandled event loop exception
Reason:
net/java/games/jogl/GLEventListener
I have installed the OpenGL plugin and (I think) everything needed to
work, but it doesn't work !!!
What have I missed ?
Thanks a lot

When you say that you've installed the OpenGL plugin, do you mean that =
you've created a new plugin that wraps the jogl.jar file? If so, did yo=
u =
also include the platform-specific library (*.dll for Windows, *.so for =
=
Unix) inside your plugin?
Incidentally, since JOGL uses AWT, are you using the SWT_AWT bridge to =
make it work with RCP? Or through some other mechanism?

and I use the gl-win32.dll for Windows XP.
My code look like that :
public void createPartControl(Composite parent) {
Vertical3DView v = new Vertical3DView();
ButtonPanel bp = new ButtonPanel(v);
Canvas canvas = new Canvas(parent, SWT.EMBEDDED);
Frame f = SWT_AWT.new_Frame(canvas);
f.setLayout(new BorderLayout()); f.add(v, BorderLayout.WEST);
f.add(bp, BorderLayout.EAST);
}
where Vertical3DView and ButtonPanel are two Jogl classes.
In a singl SWT application, this code work fine ! Then, what's the problem
with RCP, that's my question... :-)
thanks a lot,
Seb

I have no static initializer in my jogl classes.
What must I put in my Manifest.MF ? the opengl-swt plugin ? Or the
jogl.jar ?
I put a System.print(Class.forName("net.java.games.jogl.GLEventListener "))
in my plugin initializer, and the message is the following :

System.print(Class.forName("net.java.games.jogl.GLEventListener ")) which will
go through the routine of loading the class and finding any errors that are
necessary. You may even be able to stick a breakpoint on this line and go
through a debugger to find out whether it's the native library or some other
class that it can't find, but the debugger will use the same classpath as the
project builder will.

Hi,
Actually Jogl IS the openGL's library you use, and then you don't care
about SWT Opengl's one.
The plugin SWT OpenGL is not used there !!
What you need is just add the jogl.jar in the execution library list of
your plugin, you can do that using the plugin.xml editor in the
"execution/runtime" folder.
AND tell the plugin.xml to also export the lib, do that in the
"build.propserties" tab
Let's says your jogl.jar is in the "lib" folder of your plugin, the
build.properties may look like :
...
bin.includes = plugin.xml,\
plugin.properties,\
icons/,\
pluginXXXX.jar,\
lib/
Hope this help,
Arnauld

For the general case: How do I add 3rd party jar to my common plugin,
here are some steps we figured out this morning.
# for compiling with your jars
1. create your plugin project, and possibly a folder to hold them
<project>/lib
2. import the jar from the filesystem into your <project>/lib directory
3. right click on the jar and "add to build path"
4. right click on the project and do a Build Path>Configure build path
5. export the jar from the Order and Export tab
# this is probably enough for eclipse to allow you to code
# with your jar classes
# for the plugins to work when deployed
6. edit your MANIFEST.MF file
7. On the runtime tab, add your jar to the classpath pane
8. On the runtime tab, add all of the packages you want to export.
# this gets the jars into your plugin, I'm guessing
9. you might have to make sure that the jars are included in a binary
build from the Build tab, I'm not sure.
Later,
PW
