Hi...
I load jasperdesign from xml and compile.
Why can't get .jasper file and export report to pdf and html ???

JasperDesign jdesign=JasperManager.loadXmlDesign("BasicReport.xml");
JasperReport jreport=JasperCompileManager.compileReport(jdesign);
Map parameters=new HashMap();
parameters.put("ReportTitle", "Basic JasperReport");
parameters.put("MaxSalary", new Double(25000.00));

JasperPrint jprint=JasperFillManager.fillReport(jreport,parameters,new JREmptyDataSource());

JasperManager.printReportToPdfFile(jprint, "BasicReport.pdf");
JasperExportManager.exportReportToHtmlFile (jprint,"BasicReport.html");
