jasper-reports Export to pdf With Java

Example

To export a you need to fill the report to get the JasperPrint object.

Export single JasperPrint (single jrxml) to file

// 1. Create exporter instance
JRPdfExporter exporter = new JRPdfExporter();

// 2. Set exporter input document
exporter.setExporterInput(new SimpleExporterInput(jasperPrint));

// 3. Set file path for exporter output
exporter.setExporterOutput(new SimpleOutputStreamExporterOutput("/path/filename.pdf"));

// 4. Create configuration instance
SimplePdfExporterConfiguration configuration = new SimplePdfExporterConfiguration();

// 5. Associate configuration with exporter
exporter.setConfiguration(configuration);

// 6. Fill export and write to file path
exporter.exportReport();

Export multiple JasperPrint's (multiple jrxml) to single file

Only the first steps differ from the previous set:

List<JasperPrint> jasperPrintList = new ArrayList<>();
jasperPrintList.add(jasperPrint1);
jasperPrintList.add(jasperPrint2);

JRPdfExporter exporter = new JRPdfExporter();
exporter.setExporterInput(SimpleExporterInput.getInstance(jasperPrintList));

The remaining steps are the same:

exporter.setExporterOutput(new SimpleOutputStreamExporterOutput("/path/filename.pdf"));
SimplePdfExporterConfiguration configuration = new SimplePdfExporterConfiguration();
exporter.setConfiguration(configuration);
exporter.exportReport();

See SimplePdfExporterConfiguration API for configuration details.
