I can't figure it out why that is not working. That is the jsp that make me problems. I follow a tutorial from youtube and my jsp looks the same like the jsp from the video. I adapted the code from the video but i don't think that is the problem because the controller and the jsp are the same like those from the video. here is the tutorial, jsp is at min 24

and that is my controller
@Controller
public class CsvController {
@Autowired
FileValidator fileValidator;
@Autowired

@RequestMapping(value = "/uploadPage", method = RequestMethod.GET)
public ModelAndView getPage() {
ModelAndView model = new ModelAndView("upload_page");

model.addObject("formUpload", formUpload);
return model;
}

public String doUpload(@ModelAttribute("formUpload") FileUpload fileUpload, BindingResult result, RedirectAttributes redirectAttributes ) throws IOException {
fileValidator.validate(fileUpload, result);
if(result.hasErrors()) {
return "uploadPage";
} else {
redirectAttributes.addFlashAttribute("fileNames", uploadAndImportDb(fileUpload));
return "redirect:/succes";
}
}
@RequestMapping(value = "/succes", method = RequestMethod.GET)
public ModelAndView succes() {
ModelAndView model = new ModelAndView("succes");
return model;
}
private List<String> uploadAndImportDb(FileUpload fileUpload) throws IOException{
List<String> fileNames = new ArrayList<String>();
List<String> paths = new ArrayList<String>();
CommonsMultipartFile[] commonsMultipartFiles = fileUpload.getFiles();
String filePath = null;
for(CommonsMultipartFile multipartFile : commonsMultipartFiles) {
filePath = "C:\\Users\\bogda\\Desktop\\input\\" + multipartFile.getOriginalFilename();
File file = new File(filePath);
FileCopyUtils.copy(multipartFile.getBytes(), file);
fileNames.add(multipartFile.getOriginalFilename());
paths.add(filePath);
}
//parse and import
csvServices.process(paths);
return fileNames;
}
}
