获取以下代码的“NoClassDefFoundError”。

public static void exportTable(JTable table, File file){

        try{
                TableModel model = table.getModel();                    

               // FileWriter out = new FileWriter(file);

                HSSFWorkbook workBook = new HSSFWorkbook();
                HSSFSheet sheet = workBook.createSheet();
                HSSFRow headingRow = sheet.createRow(0);
                short rowNo = 1;
                for(int i=0; i < model.getColumnCount(); i++) {
                //out.write(model.getColumnName(i) + "\t");
                 headingRow.createCell((short)i).setCellValue(model.getColumnName(i));
                }
               // out.write("\n");
                for(int i=0; i< model.getRowCount(); i++) {
                     HSSFRow row = sheet.createRow(rowNo);
                     for(int j=0; j < model.getColumnCount(); j++) {
                        //out.write(model.getValueAt(i,j).toString()+"\t");
                          row.createCell((short)j).setCellValue(model.getValueAt(i,j).toString());
                    }
                     rowNo++;
               }
                  try{
                      FileOutputStream fos = new FileOutputStream(file);
                      workBook.write(fos);
                      fos.flush();
                  }catch(FileNotFoundException e){
                      e.printStackTrace();
                      System.out.println("Invalid directory or file not found");
                  }catch(IOException e){
                      e.printStackTrace();
                      System.out.println("Error occurred while writting excel file to directory");
                  }


        }catch(Exception e){
            JOptionPane.showMessageDialog(null,"Invalid File Location!");
        }
    }

我收到此错误：

线程“AWT-EventQueue-0”中的异常 java.lang.NoClassDefFoundError: org/apache/poi/hssf/usermodel/HSSFWorkbook
