I use the following code to generate PDF successfully
| Code: |
<%
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";
JasperExportManager.exportReportToPdfFile(print,destFile);
out.println("PDF created ");
