How to generate table with 3 nested list in java beans using jasper report?
Question
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();
}
}
// jasper report main file code

Let me use the terms of the example image where we are iterating over Countries , foreach which we iterate over each City , for which we iterate over each Place .
It looks to me that your inner-most iteration ( Places in the example image) needs to be an iteration per City . Thus, your subreport needs to be a subtable, ranging over all three columns.
This feels like a hacky way to do this though. Adding an iteration is a lot of clicking (or typing if working on XML directly). And the layouting only happens locally, so that the column widths of the places column of one city are potentially different for another city . See the golden lines with the pink arrows.
I am currently facing the same challenge. The only way to fix this that I came up with was to make these columns have fixed widths.
