JNLPAppletLauncher java.lang.NoClassDefFoundError
Arlo
there so I'm trying here now.
Is this error that it can't find the jar file or it can't find the
hardware specific .dll or .so library. Where is it trying to look for
them (and failing)?
I don't understand where the applet (when it's running in the browser)
is trying to find things eg
com.sun.opengl.impl.windows.WindowsGLDrawableFactory.
Although I developed this on my windows machine I've now deployed it on
my linux machine. The idea is for my windows box to act like any other
user on the web's PC.
I'm assuming (correctly?) that the JNLPAppletLauncher wraps my applet in
code thats trusted (from sun.com) and that means that any other
requirements can be obtained from the web (where? my linux box? sun?).
The purpose of the JNLP wrapper is to prevent users being faced with a
"do you trust this remote site" box and installing software just to see
my applet.
Someone also suggested the verbose appletviewer method to see the path
it's looking at but I need to test this from the browser, I already know
it works when run locally.
I've spent over a week trying to track this down
I've developed a jogl applet that runs (as an applet) in Eclipse (on
a Windows machine).
I've copied it to my webserver (a Linux machine) and I'm attempting
to run it inside a JNLPAppletLauncher. I can run a simple "hello
world" applet in this manner with no problems.
As far as I can see I've got everything needed.
When I try to run it from the windows machine I get this error:
"Exception in thread "AWT-EventQueue-32"
java.lang.NoClassDefFoundError:
Could not initialize class
com.sun.opengl.impl.windows.WindowsGLDrawableFactory"
Could someone tell me what this error - below - means (eg a jar file
can't be seen, a dll can't be retrieved, something missing on the
server, something missing on the client browser, etc).

You are trying to run this on a Linux box? You have to supply the linux
binaries (.so's) instead of dll's.
Does you code try to explicitly choose a windows graphics configuration?.
You've got something mangled.
If you are trying to run this on a windows box, well, you still have
something mangled.
Back up a step and get the JOGL applet demos (and all required dll's and 32-
and 64- bit so's) & get them working (cross-platform if required) first.

"When I try to run it from the windows machine".
It's web hosted on Linux and this test is supposed to act as a new
visitor to a site (using any client OS)
I can run it on both the machines, the problem is the launch WITHOUT the
dll or so being present. It should dynamically download them from the
sun trusted server onto any machine.
It is downloading them (and extracting them, - java console confirms
this). But then there the error I mentioned. That's what I'm trying to
diagnose.

And yet, you can run the JOGL webstart demos ... soooo
