在Excel中生成报告时，会显示以下错误消息。请帮忙!!!

代码： -

public String mainReportXLS(){

    Map<String, Object> jrxmlParams = null;

    try{

        String jrxmlFileName = "C:/Jasper/Dashboard2.jrxml";

        JasperReport objJReport = JasperCompileManager.compileReport(jrxmlFileName);
        connection = getConnection();

        JasperPrint print = JasperFillManager.fillReport(objJReport, jrxmlParams, connection);
        ByteArrayOutputStream outputByteArray = new ByteArrayOutputStream();
        //OutputStream outputfile= new FileOutputStream(new File("c:/output/JasperReport.xls"));

         JRXlsExporter exporterXLS = new JRXlsExporter();
         exporterXLS.setParameter(JRXlsExporterParameter.JASPER_PRINT, print);
         exporterXLS.setParameter(JRExporterParameter.OUTPUT_FILE_NAME, "C:/Jasper/Dashboard2.xls" );
         exporterXLS.setParameter(JRXlsExporterParameter.OUTPUT_STREAM, outputByteArray);
         exporterXLS.setParameter(JRXlsExporterParameter.IS_ONE_PAGE_PER_SHEET, Boolean.FALSE);
         exporterXLS.setParameter(JRXlsExporterParameter.IS_DETECT_CELL_TYPE, Boolean.TRUE);
         exporterXLS.setParameter(JRXlsExporterParameter.IS_WHITE_PAGE_BACKGROUND, Boolean.FALSE);
         exporterXLS.setParameter(JRXlsExporterParameter.IS_REMOVE_EMPTY_SPACE_BETWEEN_ROWS, Boolean.TRUE);
         exporterXLS.exportReport();

         //outputfile.write(outputByteArray.toByteArray()); 


    }catch (Exception e) {
           System.out.print("Exceptiion" + e);
      }

    return null;
}

请尝试以下代码，它对我有用

   File xlsx = new File("C:/Users/Sadagopan/Documents/sample.xlsX");
   JRXlsxExporter Xlsxexporter = new JRXlsxExporter();
   Xlsxexporter.setParameter(JRExporterParameter.JASPER_PRINT,
                             jasperPrint);
   Xlsxexporter.setParameter(JRExporterParameter.OUTPUT_FILE,
                             xlsx);
   Xlsxexporter.exportReport();

检查这个..“工具”＆gt; “选项”＆gt; “导出选项”标签＆gt; “PDF”各种安全选项
