我正在尝试通过在Java中使用jacob访问activeX函数。 我从注册表项中获得了activeXComponent。我必须调用一种方法。

         try{
             activeXComponent activeXComponent = new activeXComponent("actIVEX.activeXCtrl.1");
             System.out.println("The library been loaded,and an activeX component been created..");
             String filename1 =  Dispatch.call(activeXComponent,"getFaceTemplFromFile","test.jpg").toString();
             String filename2 =  Dispatch.call(activeXComponent,"test2.jpg").toString();
             System.out.println( Dispatch.call(activeXComponent,"compareFaceEx",filename1,filename2 ).toString());
         }
         catch (Exception e){
             e.printStackTrace();

         }

我遇到了雅各布错误““ com.jacob.com.ComFailException：遇到了COM异常：”。

com.jacob.com.ComFailException: A COM exception has been encountered:
At Invoke of: getFaceTemplFromFile
Description: 8000ffff / Catastrophic failure

    at com.jacob.com.Dispatch.invokev(Native Method)
    at com.jacob.com.Dispatch.invokev(Dispatch.java:625)

    at com.jacob.com.Dispatch.call(Dispatch.java:541)
    at activeXTest.main(actvieXTest.java:29)

activeXComponent仅提供功能列表。 [在此处输入图片描述] [1] 有没有办法使用提供的功能？我不确定。 请帮我解决。谢谢。
