Java运行时错误

Question

我正在 java 中制作一个 Xj3D 测试文件，并且我有一个与名为 test.x3d 和 test.x3dv 的 X3D 和 X3DV 文件一起使用的文件，该文件是同一个文件只是有两种不同的格式，它是一个红色方 block 。但是，当我尝试放入自己的 X3D 文件时，出现以下运行时错误

我的java类如下

package xj3dtest;

import java.awt.BorderLayout;
import java.awt.Container;
import static java.lang.Boolean.TRUE;
import javax.swing.JFrame;
import org.web3d.x3d.sai.Browser;
import org.web3d.x3d.sai.BrowserFactory;
import org.web3d.x3d.sai.X3DComponent;
import org.web3d.x3d.sai.X3DScene;
import java.util.HashMap;

public class Xj3DTest extends JFrame {

    public Xj3DTest(String title) {

        super(title);

        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

        // Setup browser parameters
        HashMap requestedParameters=new HashMap();
        requestedParameters.put("Antialiased",TRUE);
        requestedParameters.put("TextureQuality","medium");
        requestedParameters.put("PrimitiveQuality","medium");
        requestedParameters.put("Xj3D_InterfaceType","SWING");
        requestedParameters.put("Xj3D_NavbarShown",TRUE);
        requestedParameters.put("Xj3D_NavbarPosition","TOP");
        requestedParameters.put("Xj3D_LocationShown",TRUE);
        requestedParameters.put("Xj3D_LocationPosition","TOP");
        requestedParameters.put("Xj3D_LocationReadOnly",TRUE);
        requestedParameters.put("Xj3D_ShowConsole",TRUE);
        requestedParameters.put("Xj3D_OpenButtonShown",TRUE);
        requestedParameters.put("Xj3D_ReloadButtonShown",TRUE);
        requestedParameters.put("Xj3D_StatusBarShown",TRUE);
        requestedParameters.put("Xj3D_FPSShown",TRUE);
        requestedParameters.put("Xj3D_ContentDirectory","CurrentDirectory");
        requestedParameters.put("Xj3D_AntialiasingQuality","low");
        requestedParameters.put("Xj3D_Culling_Mode", "frustum");

        System.setProperty("x3d.sai.factory.class", "org.xj3d.ui.awt.browser.ogl.X3DOGLBrowserFactoryImpl");
        X3DComponent x3dComponent =    BrowserFactory.createX3DComponent(requestedParameters);

        Browser browser = x3dComponent.getBrowser();

        Container cp = getContentPane();
        cp.setLayout(new BorderLayout());
        cp.add((javax.swing.JPanel)x3dComponent, BorderLayout.CENTER);

        X3DScene scene = browser.createX3DFromURL(new String[]   {"hafodty_circle1.x3d"});

        browser.replaceWorld(scene);
    }

    public static void main(String[] args) {
        Xj3DTest frame = new Xj3DTest("Xj3D test");
        frame.setSize(640, 480);
        frame.setLocationRelativeTo(null);
        frame.setVisible(true);
    }
}

我正在使用 Netbeans 对此进行编程，并且已将 hafodty_circle1.x3d 和 hafodty_circle1.x3dv 保存在 Xj3DTest 项目中。我知道当我使用 test.x3d 和 test.x3dv 运行代码时出现运行时错误，但我得到了这些文件的输出，但没有得到任何输出当我运行代码时，当我有其他 x3d 文件时。任何有关此错误的帮助都意义重大，谢谢。

在“项目属性”、“运行”菜单以及“VM 选项”中。我有以下内容:

java -Djava.library.path="C:\Users\matt\Documents\NetBeansProjects\natives\Windows_10\amd64"

java -Djava.library.path="C:\Users\matt\Documents\NetBeansProjects\natives\Windows_10\x86_64"

因为我不知道应该使用哪个odejava64.dll。现在，当我运行我的项目时，出现以下错误:

Error: Could not find or load main class java

在executor-snippets中是:

此错误 UnsatisfiedLinkError 意味着您缺少 native 库(如果您在 Windows 上运行，则为 odejava.dll)，或者您使用的是 32 位具有 64 位 native 库的 Java，反之亦然。

确保系统属性java.library.path设置为包含 native 库的目录，并确保您的Java运行时环境的“位数”与 native 库相同(均为 32 位或均为 64 位)。

运行程序时，可以使用 -D 命令行选项设置 java.library.path 属性。例如，如果 odejava.dll 位于目录 C:\MyProject\lib 中:

java -Djava.library.path=C:\MyProject\lib com.myproject.MyMainClass
