I'm trying to make this program but i cannot take a report out of it... even if it worked in java netbeans when i tried to run it using the executable JAR file i get this error !
my coding part is 

```
        JRTableModelDataSource datasource = new JRTableModelDataSource(dt.getModel());
        String reportSource = "file/door_reports.JRXML";
        Map<String, Object> params = new HashMap<>();
        params.put("c1", subtot.getText());
        JasperReport jasperReport = JasperCompileManager.compileReport(reportSource);

        JasperPrint jasperPrint1 = JasperFillManager.fillReport(jasperReport, params, datasource);
        JasperViewer.viewReport(jasperPrint1, false);

```

error is : `error compiling java source file D:/test/dist/Blank_A4_1426091490655_11644`

above file do not even exist! anybody know what would be the reason?
