Having many separate - unrleated datasets in iRepo

I'm using iReport 2.0.4 to export some data to excel from a java application.

My problem is my subreports are grouping under the top level report but I want them to be discrete reports. Currently it looks like this

Order
   -Order Line 1
    Receipts
       -Receipt Line 1
       -Receipt Line 2
    Invoices
       -Invoice Line 1
       -Invoice Line 2
Order
   -Order Line 2
    Receipts
       -Receipt Line 1
       ........

I want it to be 3 separate reports in one spreadsheet. Like this

Order
    all Order lines
Receipts
    all Receipt lines
Invoices
    all Invoice lines

Currently I have the Orders as the master report and the Receipts and Invoices as subreports, dropped into the detail band Orders.

What is the best way to get this layout, if it's possible at all?

You can fill and compile three separate reports and then use JRPdfExporterParameter.JASPER_PRINT_LIST parameter for building the single report using code like this:

JasperReport ordersReport = JasperCompileManager.compileReport(srcOrdersReport);
JasperPrint jpOrdersReport = JasperFillManager.fillReport(ordersReport, ordersParamsMap, ordersDataSource);

JasperReport receiptsReport = JasperCompileManager.compileReport(srcReceiptsReport);
JasperPrint jpReceiptsReport = JasperFillManager.fillReport(receiptsReport, receiptsParamsMap, receiptsDataSource);

JasperReport invoicesReport = JasperCompileManager.compileReport(srcInvoicesReport);
JasperPrint jpInvoicesReport = JasperFillManager.fillReport(invoicesReport, invoicesParamsMap, invoicesDataSource);

List<JasperPrint> printList = new ArrayList<JasperPrint>();

printList.add(jpOrdersReport);
printList.add(receiptsReport);
printList.add(invoicesReport);

JRExporter exporter = new JRPdfExporter();
exporter.setParameter(JRPdfExporterParameter.JASPER_PRINT_LIST, printList);

exporter.setParameter(JRPdfExporterParameter.OUTPUT_STREAM, output);
exporter.exportReport();

You can look at this sample for your JR version - 2.0.4 for more details.

  • Second way. Using several datasets and list components

You can add several datasets in iReport 4.x version to the single report. Every dataset may contain its own query. The list component can use its own dataset.

In this sample (build with iReport 4.5.1) I've placed 3 list components to the Title band:

In JasperReports 6.1.1 API the JRPdfExporterParameter.JASPER_PRINT_LIST and JRPdfExporterParameter.OUTPUT_STREAM is Deprecated I add to @Alex K answer the current non deprecated metod:

"First way. Using JasperReports API"

replace (deprecated code):

exporter.setParameter(JRPdfExporterParameter.JASPER_PRINT_LIST, printList);
exporter.setParameter(JRPdfExporterParameter.OUTPUT_STREAM, output);

with

exporter.setExporterInput(SimpleExporterInput.getInstance(printList));
exporter.setExporterOutput(new SimpleOutputStreamExporterOutput(output));
