Erhalten Jxl.read.biff.BiffException Ausnahme beim Lesen .xls und .xlsx-Format Excel-Dateien

Question

Unter Verwendung von Code, ich bekomme jxl.read.biff.BiffException: Unable to recognize OLE stream. Ich möchte XLS- und XLSX-Formatdateien verwenden. Wie löst man das?

Service.java

@Override 
public boolean facultyDump(String path, HttpSession httpSession) { 
    Session session=sessionFactory.openSession(); 
    session.beginTransaction(); 
    File inputWorkbook = new File(path); 
    Workbook w; 
    try{ 
     w = Workbook.getWorkbook(inputWorkbook); 
     Sheet sheet = w.getSheet(0); 
     for (int i = 1; i < sheet.getRows(); i++) { 
      for (int j = 0; j < sheet.getColumns(); j++) { 
       Cell cell = sheet.getCell(j, i); 
       if (j == 0) { 
        String name= cell.getContents().trim(); 
       } 
      } 
     } 
    }catch(Exception ex){ 
     ex.printStackTrace(); 
    }finally{ 
     session.close();sessionFactory.close(); 
    } 
    return false; 
} 

Ausnahme bei Console:

import org.apache.poi.hssf.usermodel.HSSFSheet; 
import org.apache.poi.xssf.usermodel.XSSFSheet; 

try{ 
    FileInputStream file = new FileInputStream(new File("C:\\test.xlsx")); 

    //Get the workbook instance for XLS file 
    XSSFWorkbook workbook = new XSSFWorkbook (file); 

    //Get first sheet from the workbook 
    XSSFSheet sheet = workbook.getSheetAt(0); 

    //Get iterator to all the rows in current sheet 
    Iterator<Row> rowIterator = sheet.iterator(); 

    //Get iterator to all cells of current row 
    Iterator<Cell> cellIterator = row.cellIterator(); 

    while(cellIterator.hasNext()) { 
      Cell cell = cellIterator.next();  
      switch(cell.getCellType()) { 
       case Cell.CELL_TYPE_BOOLEAN:

        break;
