problems with java3D lib configurationJAVA3D-首先程序 - 错误
我要让使用Java 3D游戏Ubuntu的，所以我下载j3d-1_5_2-linux-i586.zip从http://www.oracle.com/technetwork/java/javasebusiness/downloads/java-archive-downloads-java-client-419417.html#java3d-1.5.1-oth-JPR，提取它。在Eclipse中，我加了3瓶在Eclipse ../j3d-1_5_2-linux-i586/lib/ext/，然后写了这个代码
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();
}
}
了这些错误

，更喜欢那些 我设置了“Forbidden reference (access rules) “从”**Error**“到”**Warning**“的”Deprecated and restricted API“下。
建设 我运行--->运行配置---> Java应用程序--->（X =）参数---> VM argiments了

，我加
-Djava.library.path=$LD_LIBRARY_PATH:/home/emil/Downloads/j3d-1_5_2-linux-i586/lib/i386/
我得到的错误
