[I got error when i use report in servlet]

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]
