JasperReport保存报表类型

Question

JasperReport jasperReport = (JasperReport) JRLoader.loadObjectFromFile("report1.jasper");
JasperPrint jasperprint2 = JasperFillManager.fillReport(jasperReport, new HashMap(), new JRBeanCollectionDataSource(DailySalesDataSource.getBeanCollection()));
JRViewer jr = new JRViewer(jasperprint2);
JFrame jf = new JFrame();
jf.setSize(500, 500);
jf.add(jr);
jf.setVisible(true);

这样，会弹出一个窗口，点窗口上面的保存按钮时，只能保存.jrprint这个文件，请问如何激活所有保存文件类型？

private void toPdfbytes(HttpServletResponse response,byte[] bb,String filename) throws SystemException { response.reset(); response.setContentType("APPLICATION/OCTET-STREAM"); response.setHeader("Content-Disposition","attachment; filename=\"" + filename + "\""); response.setContentLength(bb.length); try { ServletOutputStream ouputStream = response.getOutputStream(); ouputStream.write(bb, 0, bb.length); ouputStream.flush(); ouputStream.close(); } catch (IOException e) { e.printStackTrace(); throw new SystemException(e.getMessage()); } }response.setContentType这段，对应不同的类型！或者你直接使用：//导出为Html//JasperExportManager.exportReportToHtmlFile(jasperPrint, "c:/area.html");//导出为pdf//OutputStream output = new FileOutputStream(new File("c:/catalog.pdf")); //JasperExportManager.exportReportToPdfStream(jasperPrint,output);
