Java SE (Java Platform, Standard Edition)

i have my java j2sdk1.4.2_04 installed in the root of c:
i have j2re1.4.2_03 installled in the following location C:\Program Files\Java
i installed the java3d-1_3_1-windows-i586-opengl-sdk package, and when it asked for my install directories, it automatically picked my above locations that the sdk and jre were installed to in the prior installation. the install notes says
>
Setting CLASSPATH
If Java 3D is installed into the JDK or JRE, you do not need to include the Java 3D jar files in your CLASSPATH, nor do you need to include the Java 3D shared libraries in your PATH or LD_LIBRARY_PATH. You should include "." in your CLASSPATH or ensure that CLASSPATH is not set.

but when i try to compile the following code in netbeans 3.6, it will not complete the compile does anyone know what i did wrong?

//import Program Files\Java\j2re1.4.0_01
import javax.media.*;
import com.sun.j3d.utils;
import java.awt.*;
import javax.vecmath;

public class HelloJava3Da extends Applet
{
  ///////////////////////////////class constructor//////////////////////////////
  public HelloJava3Da()
  {
    setLayout(new BorderLayout());
    GraphicsConfiguration config = simpleUniverse.getPreferredConfiguration();
    add("Center", canvas3D);

    BranchGroup Scene = createSceneGraph();
    scene.compile();
    
    SimpleUniverse simpleU = new simpleUniverse(canvas3D);
    simpleU.addBranchGraph(scene);
    
  }

  //////////////////////////////Main////////////////////////////////////////////
  public static void main( String args[] )
  {
    Frame frame = new MainFrame(new HelloJava3Da(), 256, 256);  
  }

  public BranchGroup createSceneGraph()
  {
    BranchGroup objRoot = new BranchGroup();
    objRoot.addchild(new ColorCube(0.4));
    return objRoot;
  }
}

with the following errors
