Subreport in report's pageHeader appears at 1st page only

Posted on December 8, 2021 at 7:33am

I build reports dynamicaly with Java. My report is just a compilation of a subreports. Everything works, but when I add subreport to report's pageHeader - it appears on the first page only. When I place some static text, instead of subreport, to pageHeader - everything works fine.

Is it Jasper bug or is it my mistake somewhere?

Here is jrxml of subreport jsp_sub_header_test.jrxml:

Here how I generate PDF:

public byte[] generatePdf(List<Block> blocks) {
        ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
        try {
            // All magic happens here
            JasperPrint jasperPrint = buildJasper(blocks);
            JRPdfExporter exporter = new JRPdfExporter();
            exporter.setExporterInput(new SimpleExporterInput(jasperPrint));
            exporter.setExporterOutput(new SimpleOutputStreamExporterOutput(outputStream));
            exporter.exportReport();
        } catch (JRRuntimeException | JRException e) {
            throw new ReportProviderException(e.getMessage(), e);
        }
 
        return outputStream.toByteArray();
    }

All magic happens in buildJasper(blocks):

private JasperPrint buildJasper(List<Block> blocks) throws ReportProviderException, JRException {
         // read master report jrxml
         InputStream templateInputStream = getClass().getClassLoader().getResourceAsStream("template.jrxml");
        if (templateInputStream == null) {
            throw new ReportProviderException("Can't find classpath:template.jrxml");
        }
        JasperDesign jasperDesign = JRXmlLoader.load(templateInputStream);
        Map<String, Object> params = new HashMap<>();
 
        // here is code for inserting Bloks, nevermind
        .....
 
 
        // create a header band
        JRDesignBand headerBand = new JRDesignBand();
        headerBand.setHeight(60);

            subrepDir.setName("SUBREPORT_DIR");
            subrepDir.setValueClassName("java.lang.String");
            jasperDesign.addParameter(subrepDir);
            params.put("SUBREPORT_DIR", jasperSubreportsPath + "/testStatic/");
 
            // create dummy data source otherwise it doesn't work
            JRDesignParameter dsParameter = new JRDesignParameter();

            jasperDesign.addParameter(dsParameter);
            params.put("111", new JREmptyDataSource());
 
            JRDesignSubreport jSubreport = new JRDesignSubreport(jasperDesign);
            jSubreport.setWidth(31);

            jSubreport.setX(0);
            jSubreport.setY(0);
 
            // add our dummy data source to report
            JRDesignExpression dataSourceExpression = new JRDesignExpression();
            dataSourceExpression.setText(String.format("$P{%s}", "111"));
            jSubreport.setDataSourceExpression(dataSourceExpression);
 
            // this lines to see a preview in JasperSoft Studio (it isn't shown in preview without this lines)
            JRDesignExpression paramMapExpr = new JRDesignExpression();
            paramMapExpr.setText("$P{REPORT_PARAMETERS_MAP}");
            jSubreport.setParametersMapExpression(paramMapExpr);
 
            // add our subreport expression
            JRDesignExpression expression1 = new JRDesignExpression();
            expression1.setText("$P{SUBREPORT_DIR} + \"jsp_sub_header_test.jasper\"");
            jSubreport.setExpression(expression1);
 
            headerBand.addElement(jSubreport);
 
            // let's add dummy static text to header to check if it works
            JRDesignStaticText staticText = new JRDesignStaticText();
            staticText.setText("header created in Java");
            staticText.setX(180);
            staticText.setY(10);
            staticText.setWidth(170);
            staticText.setHeight(40);
            headerBand.addElement(staticText);
 
            jasperDesign.setPageHeader(headerBand);
 
        } catch (Exception e) {
            System.err.println(e);
        }
 
        JasperReport report = JasperCompileManager.compileReport(jasperDesign);

        JRXmlWriter.writeReport(report, "output.jrxml", "utf-8");

The result in my SprintBoot application... What we see (Pic 1)... Our static text "header created in Java" presents at all pages. But our subreport text presents at 1st page only :-((

Here is a result in my SpringBoot application. Our static text "header created in Java" presents at all pages. But our subreport text presents at 1st page only Pic 1. Subreport isn't shown at 2nd page

Here is compiled jrxml output.jrxml:

Interesting things. When I run this output.jrxml in JasperSoft Studio everything works correctly (Pic 2) O_O Pic 2. It works in JasperSoft Studio

According that I doubt if the problem in JasperFillManager or JasperCompileManager...

Does anyone understand what's wrong with me or with my code?))

UPDATE: I use Java OpenJDK 11 and
