List<FieldError> errors = result.getFieldErrors();
for (FieldError error : errors ) {
stringList += error.getObjectName() + " - " + error.getDefaultMessage() + "\n";
}
model.addAttribute("Response", stringList);
//model.addAttribute("songname", handleForm.getSongName()); works fine
//model.addAttribute("filename", handleForm.getFile().getOriginalFilename()); throws an error..?
}
return "/admin/upload";
}
}
