JRPdfExporter exporter = new JRPdfExporter();exporter.setExporterInput(new SimpleExporterInput(jasperPrint));exporter.setExporterOutput(new SimpleOutputStreamExporterOutput(outFile));SimplePdfExporterConfiguration configuration = new SimplePdfExporterConfiguration();configuration.setEncrypted(true);configuration.set128BitKey(true);configuration.setUserPassword("jasper");configuration.setOwnerPassword("reports");configuration.setPermissions(PdfWriter.ALLOW_COPY | PdfWriter.ALLOW_PRINTING);exporter.setConfiguration(configuration);

[How to use Map<String, Object> parameter]

Deal all 

 Recently started learning Jasper Report, I have some doubts about data filling.

Question 1

Map<String, Object> parameter = new HashMap<>();parameter.put("my_title", "Hi, I am title");parameter.put("myBean", new MyBean());JasperPrint jasperPrint = JasperFillManager.fillReport(jasperDesign, parameter, new JREmptyDataSource());

about this code ,

I created parameters named "my_title" and  class = java.lang.String with Jaspersoft Studio  ps: <textFieldExpression><![CDATA[$P{my_title}]]></textFieldExpression>

If I want to use javebean like jackson  such as <textFieldExpression><![CDATA[$P{myBean.name}]]></textFieldExpression>

What should I do  ?
