How to export report into PDF file

2003-10-29 19:53

Hi all,

 

I have problem to export the report into PDF file.

I can print the report and I can view the report, but I can not print it into PDF file.

Here is my code

 

Map parameters = new HashMap();

parameters.put(jTextField_parameterName.getText(), new Double(jTextField_value.getText()));

 

try {

JasperDesign jDesign = JasperManager.loadXmlDesign(SystemInfo.DEFAULT_PATH + "//xml//" + jTextField_xmlFile.getText() +".xml");

Connection conn = SystemInfo.getConnection();

JasperReport jReport = JasperManager.compileReport(jDesign);

JasperPrint jPrint = JasperManager.fillReport(jReport, parameters,conn);

//JasperViewer.viewReport(jPrint);

JasperRunManager.runReportToPdf("Jasper.pdf", parameters, conn);

//JasperManager.printReport(jPrint, true);

}

catch (Exception ex) {

JOptionPane.showMessageDialog( (JFrame)null, ex.getMessage());

}
