attendance.java

// obtains the upload file part in this multipart request
    Part filePart1 = request.getPart("OJT"+i);
    if (filePart1 != null) {
         // prints out some information for debugging
      System.out.println(filePart1.getName());
      System.out.println(filePart1.getSize());
      System.out.println(filePart1.getContentType());

我正在使用Java编译器1.8，Servlet API 3.0，Tomcat 9，MsSql，JSP，JavaScript。我收到错误消息：当我尝试更新数据或将数据输入到Sql数据库中时，类型Part的方法getSubmittedFileName（）未定义。

任何解决问题的想法。从2天开始，以前的代码现在可以正常工作了。

如何解决该错误：类型Part的方法getSubmittedFileName（）未定义
