Question

我正在使用Java创建一个加载和显示X3D模型的应用程序，我已经下载了所有正确的jars并将它们放在项目中，我可以看到每个类每个jars都包含。但是，当我在NetBeans中运行我的代码时，我收到以下错误：

No skin defined in xj3d-skin.properties
Producing default properties.
Exception in thread "main" java.lang.IllegalAccessError: tried to access method org.j3d.aviatrix3d.ViewEnvironment.<init>()V from class org.j3d.aviatrix3d.surface.BaseRenderingProcessor

我在时间点为项目提供的java代码如下所示：

package xj3dtest;

import java.awt.BorderLayout;
import java.awt.Component;
import java.awt.Container;
import static java.lang.Boolean.TRUE;
import javax.swing.JFrame;

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.web3d.ogl.browser.X3DOGLBrowserFactoryImpl");
        X3DComponent x3dComponent = BrowserFactory.createX3DComponent(requestedParameters);

        Browser browser = x3dComponent.getBrowser();

        Component browserComponent = (Component)    x3dComponent.getImplementation();

        Container cp = getContentPane();
        cp.setLayout(new BorderLayout());
        cp.add(browserComponent, BorderLayout.CENTER);

        X3DScene scene = browser.createX3DFromURL(new String[]   {"test.x3dv"});

        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);
    }
}

正如您从我收到的错误消息中可以看到的那样，我得到了java.lang.IllegalAccessError的异常，我想知道如何修复它。感谢。

我已完成修改并已下载xj3d-2.1 installer并将其放入库中并将其放入项目中。我的代码如下所示。

package xj3dtest;

        // Setup browser parameters
        HashMap requestedParameters=new HashMap();

        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[]   {"test.x3dv"});

        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);
    }
}

我现在得到的运行时错误是：

好的，我想我已经有了一些工作。

看起来您的代码是为了与Xj3D 1一起编写的。我对代码进行了一些修改以使其与Xj3D 2一起使用。首先，将调用System.setProperty的行更改为以下内容：

        System.setProperty("x3d.sai.factory.class", "org.xj3d.ui.awt.browser.ogl.X3DOGLBrowserFactoryImpl");

进行此更改的想法取自here。

其次，参数TextureQuality，PrimitiveQuality和Xj3D_AntialiasingQuality的值必须是小写的，而不是现在的大写。

第三，事实证明，X3DComponent调用返回的BrowserFactory.createX3DComponent是JPanel的子类，因此可以直接添加到Container无需致电getImplementation()。删除行

        Component browserComponent = (Component)    x3dComponent.getImplementation();

并替换

行

        cp.add(browserComponent, BorderLayout.CENTER);

与

        cp.add((javax.swing.JPanel)x3dComponent, BorderLayout.CENTER);

最后，您需要使用以下五个JAR，所有这些JAR都是由xj3d-2.1安装程序提供的，可以从here下载：

xj3d-2.1-3rdparty-nps.jar
xj3d-2.1-nps.jar
JOGL-all.jar在
joal.jar
gluegen-rt.jar中

进行这些更改后，我可以使用您的Xj3DTest类来查看X3D文件。我没有test.x3dv文件，因此我使用了the X3D file on Wikipedia。你的课似乎对我有用 - 我在Windows 10 x64上使用Java 1.8.0_60 x64，如果这有帮助 - 但它没有问题：

窗口打开大约需要两分钟。我不知道它在这段时间做了什么。 Process Explorer显示两个jogamp_exe_tstNUMBERS.exe进程，每个进程运行大约一分钟。
两分钟后出现以下消息（省略异常堆栈跟踪）：
```
SEVERE: Native code library (32 and 64 bit library) failed to load: java.lang.UnsatisfiedLinkError: no odejava in java.library.path
```
如果你能找到odejava库的二进制版本，那么你做得比我好。不过，该计划似乎没有它。

在窗口打开之前，以下消息会多次出现。同样，我不确定为什么，但他们似乎没有任何伤害：

Message: Attempting to make GL context current again in order to initialise the surface
Error: The GL context failed to initialise for some mysterious reason

程序没有彻底退出：关闭窗口后，我必须从Process Explorer中删除java.exe进程。

运行代码时出现java.lang.IllegalAccessError
