How to generate table with 3 nested list in java beans using jasper report?

[tcl44065]

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]
