Я хочу получить JasperReport из пути к файлу яшмы.Мой путь к файлу яшмы C:/project/report/reportTemplate_20110420000035982.jasper
public static JasperReport getJasperReportByTemplateName(String templateFullName) throws JRException{
JasperReport jasperReport;
jasperReport = (JasperReport)JRLoader.loadObjectFromLocation(templateFullName);
return jasperReport;
}
, и в этой строке возникает исключение:
jasperReport = (JasperReport)JRLoader.loadObjectFromLocation(templateFullName);
Я попытался найти причину, но, похоже, все в порядке.Я думаю, может быть, путь не является действительным в Windows (C:/project/report/reportTemplate_20110420000035982.jasper)
Всем, кто может мне помочь, большое спасибо.Я вставил информацию об исключении ниже.Спасибо.
