Cube.obj wont load

Question

cube.obj wont load, I installed java3d, all other java3d tutorials work except the ones with wavefront .obj models. My code is:
//Comment out the following package statement to compile separately.
package com.javaworld.media.j3d;
import java.awt.*;
import java.awt.event.*;
import java.io.*;
import javax.media.j3d.*;
import javax.vecmath.*;
import com.sun.j3d.loaders.*;
import com.sun.j3d.loaders.objectfile.*;
import com.sun.j3d.utils.geometry.*;
import com.sun.j3d.utils.universe.*;
* Example06 uses Sun's ObjectFile to load in Wavefront OBJ
* format 3D content.
* <P>
* Note that using the default ObjectFile settings does read
* in the data, but does not give the Java 3D runtime enough
* information to display the file correctly after parsing
* it. The world looks empty, though the object has been
* loaded.
* <P>
* To display and interact with OBJ content in Java 3D,
* please use Sun's more robust demo application, ObjLoad.
* (Available in the Java 3D examples download from Sun's site.)
* <P>
* This version is compliant with Java 1.2 and
* Java 3D 1.1 Beta 2, Nov 1998. Please refer to: <BR>

public class Example06 extends Frame {
* Instantiates an Example06 object.
public static void main(String args[]) {
new Example06();
* The Example06 constructor sets the frame's size, adds the
* visual components, and then makes them visible to the user.
* <P>
* We place a Canvas3D object into the Frame so that Java 3D
* has the heavyweight component it needs to render 3D
* graphics into. We then call methods to construct the
* View and Content branches of our scene graph.
public Example06() {
//Title our frame and set its size.
super("Java 3D Example06");
setSize(800,600);
//Here is our first Java 3d-specific code. We add a
//Canvas3D to our Frame so that we can render our 3D
//graphics. Java 3D requires a heavyweight component
//Canvas3D into which to render.
Canvas3D myCanvas3D = new Canvas3D(null);
add(myCanvas3D,BorderLayout.CENTER);
//Turn on the visibility of our frame.
setVisible(true);
//We want to be sure we properly dispose of resources
//this frame is using when the window is closed. We use
//an anonymous inner class adapter for this.
addWindowListener(new WindowAdapter()
{public void windowClosing(WindowEvent e)
         {dispose(); System.exit(0);}
//Use SimpleUniverse. Move viewing position so we can
//see everything in our scene.
SimpleUniverse myUniverse = new SimpleUniverse(myCanvas3D);
BranchGroup contentBranchGroup = constructContentBranch();
myUniverse.addBranchGraph(contentBranchGroup);
ViewingPlatform myView = myUniverse.getViewingPlatform();
TransformGroup myViewTransformGroup = myView.getViewPlatformTransform();
Transform3D myViewTransform = new Transform3D();
myViewTransform.setTranslation(new Vector3f(2.0f,0.0f,11.0f));
myViewTransformGroup.setTransform(myViewTransform);
* constructContentBranch() is where we specify the 3D graphics
* content to be rendered. Here we read in a square using
* Sun's OBJ loader, then return this to be rendered. This
* square could be replaced with more complicated content exported
* from 3D modeling programs supporting the OBJ format.
private BranchGroup constructContentBranch() {
ObjectFile myOBJ = new ObjectFile();
Scene myOBJScene = null;
//Attempt to load in the OBJ content using ObjectFile.
try {
myOBJScene = myOBJ.load("cube.obj");
} catch (FileNotFoundException e) {
System.out.println("Could not open OBJ file...exiting");
System.exit(1);
//Construct and return branch group containing our OBJ scene.
BranchGroup contentBranchGroup = new BranchGroup();
contentBranchGroup.addChild(myOBJScene.getSceneGroup());
return(contentBranchGroup);
}

Answer 1

Most probably the obj file is not in the right directory (it must be in the working directory as I have seen from the code).
