I design the report by studio , and build the jasper file . if I use reference the 345.jasper file , how to design the report ?

File reportFile = new File(this.getServletContext() .getRealPath("jasper/mainjiaofeiServer.jasper")); JasperReport jasperReport = (JasperReport) JRLoader.loadObject(reportFile); Map parameters = new HashMap(); File image = new File(this.getServletContext().getRealPath("/jasper/cherry.jpg")); parameters.put("image", new FileInputStream(image)); parameters.put("year", "2013"); parameters.put("clientid","1"); Class.forName("oracle.jdbc.driver.OracleDriver"); String url = "jdbc:oracle:" + "thin:@192.168.9.202:1521:orcl"; String user = "sde"; String password = "sde"; Connection conn = DriverManager.getConnection(url, user, password); JasperPrint jasperPrint = JasperFillManager.fillReport( jasperReport, parameters, conn); JasperExportManager.exportReportToHtmlFile(jasperPrint, this.getServletContext().getRealPath("/")+"test.html"); conn.close(); response.sendRedirect("test.html");[/code]
