编译某些代码以显示X3D文件时出错。运行代码时出现的错误是:
java.lang.ExceptionInInitializerError由以下引起:java.lang.RuntimeException:无法编译的源代码 - 在xj3dtest.Xj3DTest中不存在包org.web3d.x3d.sai。(Xj3DTest.java:7)线程中的异常&#34 ;主" Java结果:1
我的java代码是:
package xj3dtest;
import java.awt.BorderLayout;
import java.awt.Component;
import java.awt.Container;
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;
public class Xj3DTest extends JFrame {
public Xj3DTest(String title) {
super(title);
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
X3DComponent x3dComponent = BrowserFactory.createX3DComponent(null);
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);
}
}
在test.x3dv文件中我有:
#X3D V3.0 utf8
PROFILE Interactive
DEF TS TimeSensor {
cycleInterval 3
loop TRUE
}
DEF TG Transform {
rotation 0 1 0 0

}
ROUTE TS.fraction_changed TO OI.set_fraction
ROUTE OI.value_changed TO TG.rotation
我在第7,8,9和10行都有错误,都说他们各自的包裹都不存在。我创建了一个带有jar的Xj3D库,并且我将以下命令行放入项目属性的VM选项中:-Xmx450M -Djava.library.path =' F:\ Uni \ Uni工作\ Year Three \ xj3d-code-12559-trunk \ bin'就像我已经获得了Xj3D代码一样。
