java 3d API question

[andrey zvonerev]

I have installed Java 3D API software and wanted to start some
test programs, but all of them failed. The error messages are nearly identical, indicating NoClassDefFoundError. For example, the following error appears if I try to start HelloUniverse:

"
C:\jdk1.2\demo\java3d\HelloUniverse>java HelloUniverse
Exception in thread "main" java.lang.NoClassDefFoundError:
javax/media/j3d
GraphObject
"
Any idea how this could be corrected? Assume that JDK1.2 is installed without a fault.
Thanks in advance,
Andrey

Hello Andrey,
Don't be mad but HelloUniverse is an applet
So ... appletviewer ...
Take care.

Thanks a lot, it works with appletviewer indeed. However,it is also supposed to work two other ways, isn't it?
- with the help of a browser
- using java HelloUniverse
There is also a general file java3d\index.html to launch all demo applications, which does not work. I think that either I have missed something in the installation process, or there is a bug I am not aware of. I also suspect that since this 3D software has been developed by the Sun Microsystems already three years ago, there should be a ready answer to these simple questions somewhere in a support website. Do you know if this support (on- or offline) exists?
Sincerely,
Andrey

Hi,
Well these are all applets and they can be run with either appletviewer command or in your browser. To run it in Your browser You need a plug_in that is automatically installed when You installed jdk. The index page shows up, however I am getting the error if I want to invoke applets with the browser.
I suggest You just browse sun's 3D forum. Chances are that someone has encountered problems like these already and there should be an answer for them too.
