I am creating a table in jasper report with 3 nested lists and I successfully created the table till the 2nd list but for the 3rd list, it is not working. is there any way to do this? I am using sub-report for 2nd list. // Java code public static void main(String[] args) { String outFile = "Report.pdf"; Util util = new Util(); /* Create Vscs */ /* Create Categories */ List<Category> catogeries = new ArrayList<Category>(); int randomLength = util.getNewRandomNumber(); System.out.println("***************************"); System.out.println("Total Categories Length "+randomLength); for (int i = 0; i < randomLength; i++) { List<Vsc> Vscs = new ArrayList<Vsc>(); int vscLength = util.getNewRandomNumber(); System.out.println("***************************"); System.out.println("Total VSCs Length "+vscLength); for (int j = 0; j < vscLength; j++) { Integer id = util.getNewRandomNumber(); String temp = util.getNewRandomString(); Vscs.add(new Vsc(id, temp, temp, temp, id.toString(), id.toString(), id.toString())); } System.out.println(Vscs); String temp = util.getNewRandomString(); catogeries.add(new Category(temp, Vscs)); } System.out.println(catogeries); /* Convert List to JRBeanCollectionDataSource */ JRBeanCollectionDataSource CategoriesJRBean = new JRBeanCollectionDataSource( catogeries); /* Map to hold Jasper report Parameters */ Map<String, Object> parameters = new HashMap<String, Object>(); parameters.put("CategoryDataSource", CategoriesJRBean); /* Using compiled version(.jasper) of Jasper report to generate PDF */ try { /* Using compiled version(.jasper) of Jasper report to generate PDF */ JasperPrint jasperPrint = JasperFillManager.fillReport( "template.jasper", parameters, CategoriesJRBean); /* outputStream to create PDF */ OutputStream outStream = new FileOutputStream(new File(outFile)); /* Write content to PDF file */ JasperExportManager.exportReportToPdfStream(jasperPrint, outStream); System.out.println("File Generated"); } catch (JRException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (FileNotFoundException e) { // TODO Auto-generated catch block e.printStackTrace(); } }[/code] // jasper report main file code <?xml version="1.0" encoding="UTF-8"?> <!-- Created with Jaspersoft Studio version 6.6.0.final using JasperReports Library version 6.6.0
