How to set Jasper to use XSSF? - jasper-reports

Question

In a existing system already use jasper 5.0 and as I know it use poi HSSF to generate xls data, but now as the application grow up, the report have a problem with a big count transaction to generate.
I have search for the solution and found POI with XSSF. Because jasper use POI HSSF too, I thinking about to use XSSF inside of JASPER.
Is that possible? and how I could do that? I need to use jasper because it's not possible for now to change the existing app.

To export jrxml generating ooxml XSSF, excel file xlxs
Use the net.sf.jasperreports.engine.export.ooxml.JRXlsxExporter
Example:
JasperPrint jasperPrint = JasperFillManager.fillReport(report, paramMap, connection); //Example of how to get the jasper print
JRXlsxExporter exporter = new JRXlsxExporter();
exporter.setExporterInput(new SimpleExporterInput(jasperPrint));
File outputFile = new File("excelTest.xlsx");
exporter.setExporterOutput(new SimpleOutputStreamExporterOutput(outputFile));
SimpleXlsxReportConfiguration configuration = new SimpleXlsxReportConfiguration();
configuration.setOnePagePerSheet(false); //Set configuration as you like it!!
configuration.setDetectCellType(true);
configuration.setCollapseRowSpan(false);
exporter.setConfiguration(configuration);
exporter.exportReport();
Naturally you need related libraries (poi-ooxml.jar, poi-ooxml-schemas.jar, xmlbeans.jar) in your classpath, they are present in the distribution of jasper report.
The JRXlsxExporter is available since version 4.5 this is the jasper report 5.5.0 API. In version 4 parameters where set instead of properties please see jasperreports-export-to-xlsx-not-xls
