私はjacobライブラリを使用してExcelに取り組んでいます。基本的な操作でExcelとやり取りしようとしています。以下のコードを実行するとエラーが発生します。私は何をすべきか？

Exception in thread "main" java.lang.UnsatisfiedLinkError: com.jacob.com.Dispatch.createInstance(Ljava/lang/String;)V at com.jacob.com.Dispatch.createInstance(Native Method) at com.jacob.com.Dispatch.<init>(Dispatch.java) at com.jacob.activeX.ActiveXComponent.<init>(ActiveXComponent.java) at DispatchTest.main(DispatchTest.java:7)

public class DispatchTest {
     public static void main(String[] args)
      {

        ActiveXComponent xl = new ActiveXComponent("Excel.Application");
        Object xlo = xl.getObject();
        try {
          System.out.println("version="+xl.getProperty("Version"));
          System.out.println("version="+Dispatch.get(xlo, "Version"));
          xl.setProperty("Visible", new Variant(true));
          Object workbooks = xl.getProperty("Workbooks").toDispatch();
          Object workbook = Dispatch.get(workbooks,"Add").toDispatch();
          Object sheet = Dispatch.get(workbook,"ActiveSheet").toDispatch();
          Object a1 = Dispatch.invoke(sheet, "Range", Dispatch.Get,
                                      new Object[] {"A1"},
                                      new int[1]).toDispatch();
          Object a2 = Dispatch.invoke(sheet, "Range", Dispatch.Get,
                                      new Object[] {"A2"},
                                      new int[1]).toDispatch();
          Dispatch.put(a1, "Value", "123.456");
          Dispatch.put(a2, "Formula", "=A1*2");
          System.out.println("a1 from excel:"+Dispatch.get(a1, "Value"));
          System.out.println("a2 from excel:"+Dispatch.get(a2, "Value"));
          Variant f = new Variant(false);
          Dispatch.call(workbook, "Close", f);
        } catch (Exception e) {
          e.printStackTrace();
        } finally {
          xl.invoke("Quit", new Variant[] {});
        }
      }
}

私はこのように使用しますが、ExportAsPdfFormat にのみ使用します

final String application = "Excel.Application";
            app = new ActiveXComponent(application);
            final ActiveXComponent workbooks = app.getPropertyAsComponent("Workbooks");
            app.setProperty("visible", false);
            app.setProperty("DisplayAlerts", false);
            app.setProperty("AutomationSecurity", 3);
            d = Dispatch.call(workbooks, "Open", this.getFileName(), ExcelConverter.UPDATELINKS, Variant.VT_FALSE, Variant.VT_MISSING, Variant.VT_MISSING, Variant.VT_MISSING, Variant.VT_TRUE).toDispatch();
            Dispatch.call(d, "ExportAsFixedFormat", ExcelConverter.XLTYPEPDF, this.getConvertedFileName(), ExcelConverter.XLQUALITYSTANDARD, Variant.VT_TRUE, Variant.VT_FALSE);
