Error in reading uploaded .xlsx file using Plugin

Hi Team,

I am trying to read an uploaded excel file(.xlsx) by user using plugin.

Once the user upload the file in the form, I will try to read the file using Apache POI 3.17. But I am getting the below errors.

Code snippet:

File file = FileUtil.getFile(fileName, tableName, recordId);


System.out.println(file.getPath());

FileInputStream fip = new FileInputStream(file);

System.out.println("Before the file xls");

XSSFWorkbook workbook = new XSSFWorkbook(fip);

LogUtil.info("", workbook.getSheetAt(0).getSheetName());
