     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);

請嘗試下面的代碼，它的工作對我來說

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();

檢查這個以及..安全

再次感謝..還有一個疑問，我需要在PDF中生成報告後禁用PDF工具欄。已經從JRPDFExporter嘗試了一些參數......但無法實現。我的項目要求包括禁用PDF中的保存和打印選項。你可以好好建議。在此先感謝！ – Sainik 2013-03-06 05:38:48

請投票上面的答案..你有沒有嘗試過這個選項：'jasperreports.export.pdf.encrypted'的pdf安全？ – Sads 2013-03-06 06:55:28

檢查此。以及「工具」>「選項」>「導出選項」選項卡>「PDF」安全的各種選項。 – Sads 2013-03-06 07:00:40
