Create a catalog-excel.jsp in the JasperReports project in JDeveloper for creating a Excel spreadsheet. If an Excel report is required, use a JRXlsExporter object to export the JasperReports document to an Excel spreadsheet. Specify an OutputStream to output the Excel spreadsheet. Specify a ByteArrayOutputStream for the output from the JRXlsExporter object:

OutputStream ouputStream=new FileOutputStream
(new File("c:/JasperReports/catalog.xls"));
ByteArrayOutputStream byteArrayOutputStream = new
ByteArrayOutputStream();

Create a JRXlsExporter object and set the JasperPrint object from which the report is to be generated and the OutputStream to output the report.

JRXlsExporter exporterXLS = new JRXlsExporter();
exporterXLS.setParameter(JRXlsExporterParameter.JASPER_PRINT, print);
exporterXLS.setParameter
(JRXlsExporterParameter.OUTPUT_STREAM,byteArrayOutputStream);

Export the JasperReport document using the exportReport() method:

exporterXLS.exportReport();
