java - 使用 Java 小程序的 Phidg​​ets

Question

我正在尝试将一个 phidget 接口工具包附加到我的小程序，它给了我这个错误：

java.lang.ExceptionInInitializerError
    at AppletTest.init(AppletTest.java:15)
    at sun.applet.AppletPanel.run(AppletPanel.java:434)
    at java.lang.Thread.run(Thread.java:722)

我在phidget论坛上问过，没有回答。有没有人对 phidgets 有任何经验并知道发生了什么？

我的代码：

import java.applet.Applet;
import com.phidgets.*;
import com.phidgets.event.*;
import java.awt.*;

public class AppletTest extends Applet implements Runnable
{
  private InterfaceKitPhidget ik;

  public void init()
  {

     try
     {
        ik = new InterfaceKitPhidget();
        ik.openAny();
        System.out.println("Waiting for interface kit attachement..");
        ik.waitForAttachment();
     }
        catch (PhidgetException e)
        {
           System.out.println("Phidget Exception");
        } 

  }

  public void start()
  {
  }

  public void stop()
  {

  public void destroy()
  {

  public void paint(Graphics g)
