不知道要解决此错误：“ UnsatisfiedLinkError：../j3dcore-ogl.dll：无法在AMD 64位平台上加载IA 32位.dll”

Question

I just want to learn Java3D in Apache Netbeans (IDE 11.1) but when I implement the Java3d library, code a simple "Getting startet"-Project and want that to run I get the Error:

Exception in thread "main" java.lang.UnsatisfiedLinkError: 
C:\Windows\j3dcore-ogl.dll: Can't load IA 32-bit .dll on a AMD 64-bit platform

I have absolutely no idea how to fix that.

I already googled my problem, but there where no understandable solution for me. My first thoughts were to reinstall Netbeans and all Java JDKs. But even after this, the Programm throws the damn "UnsatisfiedLinkError"..

package javaapplication1;

import com.sun.j3d.utils.universe.SimpleUniverse;
import com.sun.j3d.utils.geometry.ColorCube;
import javax.media.j3d.BranchGroup;

public class JavaApplication1 {

    public JavaApplication1() {
        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) {
        System.setProperty("sun.awt.noerasebackground", "true");
        new JavaApplication1();
    }
}

You're using an obsolete version of Java 3D. Java 3D >= 1.6 no longer uses j3dcore-ogl, this native library was used by the native OpenGL pipeline whereas Java 3D uses only the JOGL API. I advise you to read the section of the JogAmp wiki about Java 3D . Jesper's suggestion isn't wrong, you would have a chance of making a terribly obsolete version of Java 3D work by using the 64-bit native library with a 64-bit JRE and putting it into the Java library path but a more reasonable (and easier) solution would consist in using a more recent version. I explained how to install it, just follow the link at the bottom of this page .

Note that I'm responsible for the engine support of the JogAmp community , I wrote most of those wiki pages and the official Java 3D user's guide.
