Reportes en pdf con guardado automático

[marc85]

Logré crear el archivo PDF con este código:

String urlreporte = "src/RptDxImagen.jasper";
String destino = "C:\\Reportes\\"+idserv+"\\"+idserv+".pdf";
//pdf(idpac, urlreporte, codpac);*/
try
{
Map parametros = new HashMap();
parametros.put("idserv", codserv);
JasperReport jasperReport=(JasperReport)JRLoader.loadObject(url reporte);
JasperPrint reporte = JasperFillManager.fillReport(urlreporte, parametros, con);
JRExporter exporter = new JRPdfExporter();
exporter.setParameter(JRExporterParameter.JASPER_P RINT, reporte);
exporter.setParameter(JRExporterParameter.OUTPUT_F ILE_NAME, destino);
exporter.exportReport();
//JasperExportManager.exportReportToPdfFile( reporte, destino);
//JOptionPane.showMessageDialog(null,"Diseñado");
}
catch(Exception e)
{
System.err.println( "Error iReport: " + e.getMessage() );
}

pero me crea un archivo vacío con este error que se genera en tiempo de ejecución:
