Compilar Ireport error

[piyolo]

Holas he tratado de generar un reporte en Ireport y no me funca :S:S :(
mi ultimo intento fue:

Connection cnxn = null;
try{

JasperReport jasperReport;
JasperPrint jasperPrint;
JasperDesign jasperDesign;


Conect conec = new Conect();
cnxn = conec.conectar();
//out.println(" <H1>0!!</H1>\n");

// load JasperDesign from XML and compile it into JasperReport
// fill JasperPrint using fillReport() method


out.println("********Compilamos pago_nomina.jrxml OK********");

System.setProperty(

"jasper.reports.compile.class.path",

application.getRealPath("/WEB-INF/lib/jasperreports-3.0.1.jar") +

System.getProperty("path.separator") +

application.getRealPath("/WEB-INF/classes/")

);

out.println("*****Cargamos el jasperreports-0.6.0.jar OK*********");

System.setProperty(

"jasper.reports.compile.temp",

application.getRealPath("/GUI/")

);



JasperCompileManager.compileReportToFile(applicati on.getRealPath("/GUI/1.jrxml"));



out.println("******Fin de la Compilamos el archivos***********");

/////////////////////////////////////////////



File reportFile = new File(application.getRealPath("/GUI/1.jasper"));



Map parameters = new HashMap();
parameters.put("id", "13415640-6");


byte[] bytes =

JasperRunManager.runReportToPdf(

reportFile.getPath(),

parameters,

cnxn

);



response.setContentType("application/pdf");

response.setContentLength(bytes.length);

ServletOutputStream ouputStream = response.getOutputStream();

ouputStream.write(bytes, 0, bytes.length);

ouputStream.flush();

ouputStream.close();



out.println("jasperPDF OK..............");

///////////////////////////////////////////////////////////////

out.println("Fin del reporte pago_reporte_nomina.............");



}catch (JRException e){
out.println("Error:" +e.getMessage());
StringWriter stringWriter = new StringWriter();
PrintWriter printWriter = new PrintWriter(stringWriter);
e.printStackTrace(printWriter);
response.setContentType("text/plain");
response.getOutputStream().print(stringWriter.toSt ring());
}

catch (Exception e)

{

e.printStackTrace();

out.println("Error2:" +e.getMessage());

}
