Ireport怎么将做成的报表通过JSP页面调用并输出打印？

File reportFile = new File(application.getRealPath("report/test.jasper"));
JasperReport jasperReport = (JasperReport) JRLoader.loadObject(reportFile.getPath());
Map parameters = new HashMap();
String str0 = request.getParameter("time");
String str1 = request.getParameter("no");
String str2 = request.getParameter("name");
parameters.put("time", str0);
parameters.put("no", str1);
parameters.put("name", str2);
Class.forName("com.mysql.jdbc.Driver");
Connection conn = DriverManager.getConnection("jdbc:mysql://localhost:3306/test","root", "root");
JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport, parameters, conn);

JRHtmlExporter exporter = new JRHtmlExporter();
exporter.setParameter(JRExporterParameter.JASPER_PRINT, jasperPrint);
exporter.setParameter(JRExporterParameter.OUTPUT_WRITER, out);
exporter.setParameter(JRHtmlExporterParameter.IS_USING_IMAGES_TO_ALIGN,Boolean.FALSE);
exporter.exportReport();
out.flush();
conn.close();
out.clear();
out = pageContext.pushBody();
