我有一个小型测试程序，可以在JBuilder 6调试器中完美运行。当我制作一个.jar文件并运行它时，出现错误

>java -jar testadll.jar
Start of DLL test
Exception in thread "main" java.lang.UnsatisfiedLinkError: jnidispatch (/com/sun
/jna/win32-x86/jnidispatch.dll) not found in resource path
    at com.sun.jna.Native.loadNativeLibraryFromJar(Native.java:708)
    at com.sun.jna.Native.loadNativeLibrary(Native.java:685)
    at com.sun.jna.Native.<clinit>(Native.java:109)
    at testadll.TestThisDLL$PenniesLib.<clinit>(TestThisDLL.java:24)
    at testadll.TestThisDLL.main(TestThisDLL.java:33)

我已经搜索了驱动器，但是没有jnidispatch.dll。

该程序是

package testadll;

import com.sun.jna.Library;
import com.sun.jna.Native;
//import com.sun.jna.NativeLong;
import com.sun.jna.Platform;
import com.sun.jna.win32.StdCallLibrary;
//import com.sun.jna.*;



public class TestThisDLL {
   public interface PenniesLib extends StdCallLibrary {
    PenniesLib INSTANCE = (PenniesLib) Native.loadLibrary(
            "PenniesLib", PenniesLib.class);
        int a();
    }

  public static void main( String args[] ) {
      System.out.println("Start of DLL test");
      //TestDLL t = new TestDLL();
      //System.out.println("DLL loaded");
      int value = PenniesLib.INSTANCE.a();
      System.out.println("DLL response is " + String.valueOf(value));
  }
}
