Code: Select all

public UploadBean() {
    }

    public void handleFileUpload(FileUploadEvent event) {

    ExternalContext extContext = FacesContext.getCurrentInstance().getExternalContext();
    File result = new File(extContext.getRealPath("\\Configuracion\\logo") + "\\" + event.getFile().getFileName());

try {
    FileOutputStream fileOutputStream = new FileOutputStream(result);

    byte[] buffer = new byte[BUFFER_SIZE];

    int bulk;
    InputStream inputStream = event.getFile().getInputstream();
    while (true) {
      bulk = inputStream.read(buffer);
      if (bulk < 0) {
             break;
             }
      fileOutputStream.write(buffer, 0, bulk);
      fileOutputStream.flush();
      }

      fileOutputStream.close();
      inputStream.close();

      FacesMessage msg = new FacesMessage("Succesful", event.getFile().getFileName() + " is uploaded.");
      FacesContext.getCurrentInstance().addMessage(null, msg);

      } catch (IOException e) {
            e.printStackTrace();

      FacesMessage error = new FacesMessage("The files were not uploaded!");
      FacesContext.getCurrentInstance().addMessage(null, error);
      }
    }
