Jasper Subreport Not Working for Me

Recommended Posts

Struggling with this for a week, and yes I progressed slightly thanks to previous posts on the same subject however, not completely. Two reports: Master Report - Contains company info Sub Report - Contains 1..* company orders in detail list


The data source is built from pojo array lists:


Master Report:


 


<parameter name="SUB_REPORT" class="java.lang.Object"/>
<queryString>
<![CDATA[]]>
</queryString>
<field name="companyName" class="java.lang.String">
<fieldDescription><![CDATA[companyName]]></fieldDescription>

The java code that I use to compile and print the reports at runtime:


 


CompanyMapper cm = new CompanyMapper();  
this.company = cm.getCompanyByID((Long) httpRequest.getSession().getAttribute("userCompanyID"));
List<ACompany> c = new ArrayList<ACompany>();
List<AOrder> companyOrders = getOrders(getParameterInt("orderStatus"));

c.add(this.company);

String reportFolder = httpRequest.getServletContext().getRealPath("/").replace('\', '/') + "reports/";
String invoice = reportFolder + ReportManager.getProperty("orders");
String orders = reportFolder + ReportManager.getProperty("orderList");
File invoiceFile = new File(invoice);
File orderFile = new File(orders);
msgHelper = new MessageHelper();

JasperReport jasperMasterReport = JasperCompileManager.compileReport(invoiceFile.getAbsolutePath());
JasperReport jasperSubReport = JasperCompileManager.compileReport(orderFile.getAbsolutePath());

Map<String,Object> parameters = new HashMap<String,Object>();
parameters.put("SUB_REPORT", jasperSubReport);
parameters.put("SUB_REPORT_DATA", new JRBeanCollectionDataSource(companyOrders));

JasperFillManager.fillReport(jasperSubReport, parameters, new JRBeanCollectionDataSource(companyOrders));
JasperPrint print = JasperFillManager.fillReport(jasperMasterReport, parameters, new JRBeanCollectionDataSource©); [/code]

Company info show up fine in the Master report however, no orders in details are printed from the sub report. When I print the subreport, there is data (ie, detail of orders) showing up as expected. I just want to pass the subreport in the detail section of the master, and everything will be perfect.


Thanks in Advance.
