I'm trying to display a sphere, but I get an error.

[Astralogic]

Hi, I installed Java3D but it's not behaving correctly. Here's my code:

import com.sun.j3d.utils.geometry.*;
import com.sun.j3d.utils.universe.*;
import javax.media.j3d.*;
import javax.vecmath.*;

public class ThreeDball {
	
	public static void main(String[] args) {
		SimpleUniverse uni = new SimpleUniverse();
		BranchGroup group = new BranchGroup();
		Sphere ball = new Sphere(0.5f);
		
		uni.addBranchGraph(group);
		
		Color3f color = new Color3f(2,2,0);
		BoundingSphere bounds = new BoundingSphere(new Point3d(0,0,0), 1000);
		Vector3f direction = new Vector3f(5, -6, -10);
		DirectionalLight light = new DirectionalLight(color, direction);
		light.setInfluencingBounds(bounds);
		group.addChild(light);
		group.addChild(ball);
		uni.getViewingPlatform().setNominalViewingTransform();
	}

}

However all I get is a bunch of access restriction errors:

I know I can change Eclipses behavior to just give a warning instead of an error with regards to access restrictions, and doing that removes all the errors, but I get this runtime error:

Exception in thread "main" javax.media.j3d.RestrictedAccessException: Group: only a BranchGroup node may be added
at javax.media.j3d.Group.addChild(Group.java:265)
at ThreeDball.main(ThreeDball.java:22)

Also because of this access restriction thing I can't use CTRL+space to finish method and variable names related to Java3D.

Any ideas how I can fix this?

Thanks

I'm also having this problem with another program that doesn't use Java3D at all. I'm just trying to play an mp3 file.

import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.io.FileInputStream;
import java.io.IOException;

import javax.swing.JButton;
import javax.swing.JFrame;
import sun.audio.*;

public class Sound {

	public static void main(String[] args) {
		JFrame frame = new JFrame();
		frame.setSize(200, 200);
		JButton button = new JButton("Play");
		frame.add(button);
		button.addActionListener(new AL());
		frame.setVisible(true);
	}
	
	public static class AL implements ActionListener {
		public final void actionPerformed(ActionEvent e) {
			music();			
		}
	}
	
	public static void music() {
		AudioPlayer player = AudioPlayer.player;
		AudioStream stream;
		AudioData data;
		ContinuousAudioDataStream loop = null;
		
		try {
			stream = new AudioStream(new FileInputStream("Vampire Hunter D - Medieval Song.mp3"));
			data = stream.getData();
			loop = new ContinuousAudioDataStream(data);
		} catch (IOException e) {
			
		}
                player.start(loop);
		
	}
}

Practically everything in the music() method is underlined red with an access restriction. All the things that are used for audio that is.

Here's the error output:

Again I can change the settings so access restrictions don't prevent the program from running, but doing so I can't hear any sound when I press the play button.

If you move

uni.addBranchGraph(group);

to the end it works.
(You can't add lights and balls to a "living" group)

Thanks Jodokus, it's strange though I got this code from a youtube video and it worked fine for him in that order (he was using netbeans though).

But don't you have any idea where all these access restrictions are coming from and how I can get unrestricted access?

No, I did'n't have them. Did you manage to run the code? Maybe reinstalling Java3D is a good idea. (I had to do it because of an update, and it worked fine again immediately. Because it is complaining about all the jars it's possible it can't find the needed "connect to native code-" dll. You can set the path but reinstalling is easy).

Just some Java3D tips:
- It is good, and very nice to practice 3d-programming, but not easy to deploy once finished, and a bit outdated. I started with JMonkey (it also has a physics-engine), which feels much more modern and integrated, but there are more programs to choose from.
- If you stick to Java3D and once you are more experienced: I had much fun combining it with ODE (a physics engine). Then you can make cars or billiards with balls that really fall of the table.
- Book 1, a classic: Java 3D Programming (Daniel Selman, Manning, 2002)
- Book 2: Killer Game Programming in Java (O'Reilly, 2005) Very nice and good working examples.

[Astralogic]

I just realized I quoted several separate programs errors in the output log. I've corrected the error quote in my second post.

Will reinstalling Java3D help with the audio errors in the second program I posted? It seems those libraries aren't related to Java3D, or are they?

I recently did an update from Java 1.6 to 1.7. Is it possible I did it wrong and that's what's causing this problem?

Oh and yes the code ran fine after moving that line to the end, sorry I forgot to mention that.

[Jodokus]

I hardly looked at the "access restriction" errors, but indeed the second program has nothing to do with Java3D. My "upgrade" also was from Java 1.6 to 1.7, after which Java3D didn't find the dll anymore. Reinstalling worked, so hence my reinstalling advice. Your other program uses nothing exotic, except sun.audio. Does that need a dll? It doesn't seem to have to do with j3daudio.jar but maybe it uses some dll. This is guessing though, and google doesn't seem to mention it.

Nice that your code was running, success with the 3D-programming!

[Astralogic]

Thanks for the help Jodokus.

Any ideas?

Yes, try it without the starting slash (if it's not in the root anyway).
But frankly, I started reacting to the J3D-problem, not to debug the second.
I might help of course if you have some specific J3D (or any type) problem I know about

No worries, I know just where to take this problem.
