I have two tables to be printed in same page. Data for those tables will be supplied from a map from a custom data source. I need to implement it. I googled for implementing this task.

At that time I came across sub-reports concept, but I didn’t get much info for how to implement sub-reports.

I have an idea of how to create sub-reports. But I don’t know how to fill sub reports with customdatasource. That’s my question. Please help me in achieving this.

Note: I tried to implement subreports, but I am getting an error. Here is the code I used for compiling subreports:

JasperPrint print = new JasperPrint();
JRPdfExporter exporter = new JRPdfExporter();
JasperDesign design, design1;
JasperReport report, report1;
JasperReport jasperReport;
JasperDesign jd1;

jd1 = JRXmlLoader.load("D:\\sub_report1.jrxml");
jasperReport = JasperCompileManager.compileReport(jd1);
Map parameters = new HashMap();
parameters.put("ReportTitle", "Table Report");
parameters.put("DataFile", "TableSource.java");
parameters.put("Subreport_1", jasperReport);

design = JRXmlLoader.load("D:\\sub_report2.jrxml");
report = JasperCompileManager.compileReport(design);
parameters.put("Subreport_2", report);

design1 = JRXmlLoader.load("D:\\master_report.jrxml");
report1 = JasperCompileManager.compileReport(design1);
JasperFillManager.fillReportToFile(report1, "D:\\master_report.jrprint", parameters, new TableDataSource());

exporter.setParameter(JRExporterParameter.JASPER_PRINT, print);
exporter.setParameter(JRExporterParameter.OUTPUT_FILE_NAME, "D:K\\Report.pdf");
exporter.exportReport();

JasperViewer.viewReport(print);

Here I have compiled subreport1 & subreport2 individually and added them as a parameter in map. Then I’m getting an error while filling it through masterreports. Please help me to compile the report.
