Mac JDK 7 signing Jars

Hi, I'm battling getting a simple J3D demo working. I believe it is issues with jar signing. I get the error:

basic: PERF: AppletExecutionRunnable - applet.init() BEGIN ; jvmLaunch dt 141816 us, pluginInit dt 4104943 us, TotalTime: 4246759 us

I've copied all the jars from gluegen, jogl & Java3D into the one location.
 
My applet looks like:

My testj3d.jnlp looks like:

I wrote a little script to help with signing all the jars. I used SHA-256 because otherwise it was giving an error saying it was corrupt when I was trying to verify it using jarsigner.

jarsigner -keystore testKeys -storepass $1 -digestalg SHA-256  gluegen-rt.jar ww
jarsigner -keystore testKeys -storepass $1 -digestalg SHA-256 jogl-all.jar ww

thanks in advance for any pointers

btw, I'm on Mountain Lion. It would be great if there was a Java3D applet demo to download, similar to the other demos. I appreciate the work you are all doing keeping Java3D alive, so I'm happy with any help I can get.

Hi

It doesn't find your own classes.

Thanks for replying Julien,

I didn't understand what you meant by finding my own classes as it did get into my applet code OK. I realised that it was picking up a legacy j3dcore, which is why it was trying to load a native lib in J3D. I had renamed the j3dcore (and other) jars in /System/Library/Java/Extensions to j3dcore.jar.old, but it appears that it was still getting read. Once I deleted them, I then  progressed to the crashing applet/console similar to:
http://forum.jogamp.org/Java3D-applet-tests-on-Mac-OS-X-10-7-5-td4027164.html

I added the OffscreenLayerOption fix by interactiveMesh (http://forum.jogamp.org/Issue-with-Java-3D-under-OpenJDK-7-Mac-OS-X-tp4025259p4027375.html), and now I can see the applet running in a popup window.

thanks again all.
