動作類應具有以下三個屬性。
•[inputName]文件
•[inputName]文件名
•[inputName]的ContentType

[inputName]是在JSP文件標籤（一個或多個）的名稱。例如，如果文件標記的名稱是uploadphoto，性能將是如下：
•文件uploadphotoFile
•字符串uploadphotoFileName
•字符串uploadphotoContentType

String filePath = servletRequest.getRealPath("/"); 
File fileToCreate = new File(filePath, this.uploadphotoFileName); 
FileUtils.copyFile(this.uploadphotoFile, fileToCreate);
