How to design report with tabular format?

Question

I have a requirement to design in ireport.

I have three VOs

DeliveryAllocations {
    private String collectorCode;
    private String collectorName         


        

Answer 1

This is done by for example using a subreport and passing as datasource

new net.sf.jasperreports.engine.data.JRBeanCollectionDataSource($F{allocations})

Example code:

Main report (PlantVO.jrxml)

Sub report (PlantAllocationVO_subreport)

With main code

JasperReport report = JasperCompileManager.compileReport("PlantVO.jrxml");
Map map = new HashMap();
JasperPrint print = JasperFillManager.fillReport(report, map,new JRBeanCollectionDataSource(deliveryAllocations.getPlants()));
JasperExportManager.exportReportToPdfFile(print, "PlantVO.pdf");

Will produce this result:

Some design notes:

1. I would keep correct type of fields (es. weight as a Double or Integer) and apply pattern in jrxml (see example), this will help you do correct export to excel.

2. TotalWeight there is no really need to have this as a field, it could be calculated by subreport and passed back to main report.
