ここで何が間違っていますか？JTextFields の値は有効で、コードは結果をコンソールに出力します。ワークスペースにファイルを取得しましたが、サイズが 0b で、空のスプレッドシートが表示されます。

    String _path;
    int _column;

    public convertFileAction(JTextField tfFilePath, JTextField tfWhichColumn) {
        _filePath = tfFilePath;
        _whichColumn = tfWhichColumn;
    }

    @Override
    public void actionPerformed(ActionEvent e) {
        _path = _filePath.getText();
        _file = new File(_path);
        _column = Integer.parseInt(_whichColumn.getText());
        _column = _column - 1;

        try {
            WorkbookSettings wbSettings = new WorkbookSettings();
            wbSettings.setUseTemporaryFileDuringWrite(true);
            Workbook workbook = Workbook.getWorkbook(_file);
            // System.out.println(""+_file.exists());
            Sheet sheet = workbook.getSheet(0);
            WritableWorkbook genWorkbook = Workbook.createWorkbook(new File(
                    "output.xls"));
            WritableSheet genSheet = genWorkbook.createSheet("Ad IDs", 0);
            Label headerIc = new Label(1, 1, "ifContexts");
            genSheet.addCell(headerIc);
            for (int i = 0; sheet.getCell(_column, i) != null; i++) {
                Cell c = sheet.getCell(_column, i);
                    CellFormat readFormat = c.getCellFormat();
                    WritableCellFormat writeFormat = new WritableCellFormat(
                            readFormat);
                    System.out.println(c.getContents());
                    String ifContext = c.getContents().toString();
                    Label labIfContext = new Label(1, i + 1, ifContext);
                    labIfContext.setCellFormat(writeFormat);
                    genSheet.addCell(labIfContext);
            }
            genWorkbook.write();
            workbook.close();
            genWorkbook.close();

        } catch (BiffException | IOException e1) {
            // TODO Auto-generated catch block
            e1.printStackTrace();
        } catch (RowsExceededException e1) {
            // TODO Auto-generated catch block
            e1.printStackTrace();
        } catch (WriteException e1) {
            // TODO Auto-generated catch block
            e1.printStackTrace();
        }

    }

}

コンソールにエラーが表示されますが、それが関連しているかどうかはわかりません。とにかくここにあります：

とても有難い。

これを試して.....

              CellFormat readFormat = c.getCellFormat();
                System.out.println(c.getContents());
                String ifContext = c.getContents().toString();
                Label labIfContext = new Label(1, i + 1, ifContext);
                labIfContext.setCellFormat(readFormat);
                genSheet.addCell(labIfContext);
