Answer 1

You will need to know at runtime if you are exporting to Excel or PDF, which you should know.

Just as an example:

public void generateReport(JasperPrint report, boolean isExcel, String saveTo){
  JRExporter exporter = null;
  if (isExcel) {
    exporter = new JRXlsExporter();
    exporter.setParameter(JRXlsExporterParameter.IS_REMOVE_EMPTY_SPACE_BETWEEN_ROWS, Boolean.TRUE);
    exporter.setParameter(JRXlsExporterParameter.IS_WHITE_PAGE_BACKGROUND, Boolean.FALSE);
    exporter.setParameter(JRXlsExporterParameter.IS_DETECT_CELL_TYPE, Boolean.TRUE);
    //we set the one page per sheet parameter here
    exporter.setParameter(JRXlsExporterParameter.IS_ONE_PAGE_PER_SHEET, Boolean.TRUE);
  } else {
    exporter = new JRPdfExporter();     
  }
  exporter.setParameter(JRExporterParameter.JASPER_PRINT, jasperPrint);124
  exporter.setParameter(JRExporterParameter.OUTPUT_FILE_NAME, saveTo);
  export.exportReport();
}
