Генерация пустой таблицы из DynamicJasper

Question

Я пытаюсь создать таблицу с пользовательским шаблоном яшмы и с входным параметром. Однако я всегда заканчиваю с пустым PDF.

Мой jrxml

Мой основной класс

public class ItemPriceReporter {

    public static void main(String[] args) throws FileNotFoundException, JRException {
        new ItemPriceReporter().generateReport();
    }

    private void generateReport() throws JRException, FileNotFoundException {
        DynamicReportBuilder drb = new DynamicReportBuilder();
        drb.setTemplateFile("TestTable.jrxml");
        Map<String, Object> params = new HashMap<>();
        JRBeanCollectionDataSource dataSource = new JRBeanCollectionDataSource(generateItems());
        params.put("TestParam", dataSource);
        JasperReport jasperReport = DynamicJasperHelper.generateJasperReport(drb.build(), new ClassicLayoutManager(), params);
        JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport, params, new JREmptyDataSource());
        JRPdfExporter pdfExporter = new JRPdfExporter();
        pdfExporter.setExporterInput(new SimpleExporterInput(jasperPrint));
        FileOutputStream fos = new FileOutputStream("TestTable.pdf");
        pdfExporter.setExporterOutput(new SimpleOutputStreamExporterOutput(fos));
        pdfExporter.exportReport();
    }

    private List<Item> generateItems() {
        List<Item> items = new ArrayList<>();
        Item item = new Item("test", "10");
        items.add(item);
        item = new Item("test2", "20");
        items.add(item);
        return items;
    }
}

Мой товар бин

public class Item {
    private String name;
    private String price;

    public Item() {
    }

    public Item(String name, String price) {
        this.name = name;
        this.price = price;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getPrice() {
        return price;
    }

    public void setPrice(String price) {
        this.price = price;
    }
}

Кто-то может указать, что я здесь скучаю?
