How to generate dynamically jasper report for JAVA

[samuel.davidov]

I have .jrxml with generating the PDF and everthing works fine. But sometimes i need to add dynamically another item of table's items. 

How to do that? I'm new in this field and only once to create this pdf.

Also attached the format of output.

I have this json:

{  "customerName": "derr",  "customerEmail": "sss.dd@gmail.com",  "invoiceNumber": "1",  "invoiceAmount": "180",  "invoiceDate": "2021-08-30",  "poNumber": "234234",  "productName": "Hilton Milano",  "price": "180",  "vat": "0",  "lineTotal": "180",  "currency": "EUR"}[/code]

And i think to change to new format:

{  "customerName": "derr",  "customerEmail": "sss.dd@gmail.com",  "items": [    {      "invoiceNumber": "1",      "invoiceAmount": "180",      "invoiceDate": "2021-08-30",      "poNumber": "234234",      "productName": "Hilton Milano",      "price": "180",      "vat": "0",      "lineTotal": "180",      "currency": "EUR"    },    {      "invoiceNumber": "2",      "invoiceAmount": "180",      "invoiceDate": "2021-08-30",      "poNumber": "45455",      "productName": "Item2",      "price": "180",      "vat": "0",      "lineTotal": "180",      "currency": "EUR"    }  ]}[/code]

and this is a java block that generates the PDF

 [/code]

    // Generating PDF invoice    public byte[] generateInvoiceFor(String pdfInvoiceParameters) {        try {            LOGGER.debug("Generating pdf invoice for user: [{}]", "x");            validateXmlFormat(pdfJasperReportXml);            // Load invoice jrxml template.            JasperDesign design = JRXmlLoader.load(new ByteArrayInputStream(pdfJasperReportXml.getBytes(StandardCharsets.UTF_8)));            JasperReport report = JasperCompileManager.compileReport(design);            // Create parameters map.            Map<String, Object> parameters = buildParametrsMap(pdfInvoiceParameters);            // Fill the template with parameters map.            JasperPrint jasperPrint = JasperFillManager.fillReport(report, parameters, new JREmptyDataSource());            return JasperExportManager.exportReportToPdf(jasperPrint);        } catch (SAXException saxEx) {            LOGGER.error("XML format is not correct for following PDF template {} and exception has raised : {} ", pdfJasperReportXml, saxEx.getMessage());            return null;        } catch (JsonProcessingException jsonEx) {            LOGGER.error("Json params format error for {} and exception has raised : {} ", pdfInvoiceParameters, jsonEx.getMessage());            return null;        } catch (Exception e) {            LOGGER.error("Error has occured {}", e);            return null;        }    }    // Fill template order parametres    private Map<String, Object> buildParametrsMap(String pdfInvoiceParameters) throws JsonProcessingException {        Map<String, Object> pdfInvoiceParams = mapper.readValue(pdfInvoiceParameters, Map.class);//         pdfInvoiceParams.put("logo", resourcesInvoiceImagesPath + "logo.jpg");       [/code]

Output PDF

 

 

So actually need to add dynamically to add the items if they present in parameters like first row item1 with its price, then new row item2 with its price and etc.
