hey, so I am just starting java3D, and I am running into some pretty basic problems... I started a tutorial online (from www.java3d.org) and the first sample program is:

import com.sun.j3d.utils.universe.SimpleUniverse;
import com.sun.j3d.utils.geometry.ColorCube;
import javax.media.j3d.BranchGroup;
public class Hello3d {
public Hello3d()
{
   SimpleUniverse universe = new SimpleUniverse();
   BranchGroup group = new BranchGroup();
   group.addChild(new ColorCube(0.3));
   universe.getViewingPlatform().setNominalViewingTransform();
   universe.addBranchGraph(group);
}
public static void main( String[] args ) {
   new Hello3d();
}
} // end of class Hello3d

with error output

java.lang.NoClassDefFoundError: javax/media/j3d/Node
	at java.lang.Class.getDeclaredMethods0(Native Method)
	at java.lang.Class.privateGetDeclaredMethods(Class.java:2427)
	at java.lang.Class.getMethod0(Class.java:2670)
	at java.lang.Class.getMethod(Class.java:1603)
	at edu.rice.cs.drjava.model.compiler.JavacCompiler.runCommand(JavacCompiler.java:251)

I think (and correct me if I'm wrong) that means that the the class definiton 'javax/media/j3d/Node' in 'javax/media/j3d' does not exist, and I have to install something else.

OR, i could just be wrong about what the problem is, and I am misinterpreting the output...

In any event, how do I fix this?

Edited 4 Years Ago by FALL3N: n/a

I could be wrong but BranchGroup inside javax sounds doubtful.

javax is a standard java library and it does not contain a media class. if it is to contain it, you should download that. look online for javax.media library.

thank you, from that link I was lead to the download 'j3d-core-1.3.1.jar'

and from another search, I found http://www.codeguru.com/forum/archive/index.php/t-339490.html
which contains a link that leads me to download the 'JMF-2.1.1e' framework (universal port, as I am using a mac and not Windows, linux or Solaris)

I assume what I found is not right for this, but using the .jar from your link, how should I install it? Should I add it to by path? put it in my lib folder? or run it? or do something else totally different?

UPDATE:
I successfully compiled and ran the above program in Eclipse, and that Eclipse .java file via command line. In Eclipse it did run, but it asked if it should 'ignore errors and run anyway' or something...

What's the problem and/or how can I fix it?

I believe you need to put your jar file in your library folder, I'm sure the place where you got your jar should explain how to install it...

put the errors you get here and we might see what the actual problems are.

well, eclipse is running despite errors, and the program is doing what is described in the tutorial... so sorta no problems..

I guess technically the errors are this, but I sorta don't need to fix them:

I believe you need to put your jar file in your library folder

when u say 'library folder' do u mean the single-user one, the one for all users or lib OR something else that I don't even know about?

'm sure the place where you got your jar should explain how to install it...
