可能重复：
problems with java3D lib configuration

我想在 Ubuntu 上使用JAVA创建一个3D游戏，因此我从j3d-1_5_2-linux-i586.zip下载了http://www.oracle.com/technetwork/java/javasebusiness/downloads/java-archive-downloads-java-client-419417.html#java3d-1.5.1-oth-JPR，将其解压缩。在 Eclipse 中，我在eclipse中的../j3d-1_5_2-linux-i586/lib/ext/中添加了3个jar，然后编写了这段代码

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();
    }

}

遇到了这些错误

，更像那些 我设置了＆＃34; Forbidden reference (access rules)＆＃34;在＆＃34; Deprecated and restricted API＆＃34;来自＆＃34; **Error**＆＃34;到＆＃34; **Warning**＆＃34;。

运行---＆gt;运行配置---＆gt; JAVA应用程序---＆gt;（x =）参数---＆gt; VM argiments ，我添加了

-Djava.library.path=$LD_LIBRARY_PATH:/home/emil/Downloads/j3d-1_5_2-linux-i586/lib/i386/

我收到了这个错误
