 I use the following code to generate PDF successfully

            Connection con=null;
           Mydao ad = new Mydao();
            con = ad.getConnection();
            Map parameters = new HashMap();
            parameters.put("param1", "PH2011-001");
            JasperReport report = JasperCompileManager.compileReport("demo.jrxml");
  JasperPrint print = JasperFillManager.fillReport(report, parameters, con);
                        String  destFile = "NAME OF PDF FILE";
                        out.println("PDF created ");
        <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
        <title><strong class="highlight">JSP</strong> Page</title>
