Vraptor - Upload

Assuntos Gerais
#81

Boa noite! Estou com um problema igualzinho do cara que criou o tópico: Eu passo o file como parâmetro mas ele vem null… Porém como já pesquisei em 43737662834 tópicos eu vi que o problema era o bendito jar ou o povo esqueceu de colocar o multipart/form-data. Mas não sei o que fazer pois está tudo perfeito(Perfeito mesmo) não tem problema nenhum com os jars.
Uso netbeans, VRaptor 3.3.1 e o glassfish como servidor.

  private final AlbumDAO dao;
  private final HttpServletRequest request;
  private final File img;

  public AlbunsController(Result result, AlbumDAO dao, HttpServletRequest request, ServletContext context) {
    this.img = new File(context.getRealPath("/img"));

    this.result = result;
    this.dao = dao;
    this.request = request;
  }
  
  @Path("/admin/UploadCapa.brz")

    File destino = new File(img, imagem.getFileName());

    try {

    } catch (IOException e) {
      throw new RuntimeException("Não foi possível copiar a imagem!");
    }

vc colocou o jar da commons-fileupload no WEB-INF/lib?

liga o log de info do vraptor, e ve se aparece alguma mensagem sobre multipart

Peguei um pouco das infos antes do erro. Você sabe como aumenta o tamanho máximo do arquivo?

#84

se o tamanho estoura ele vai null sim… a primeira linha do seu método do upload tem que ser algo do tipo:

validator.onErrorRedirectTo(this).formulario();

assim ele redireciona com erro de validação

#85

Obrigado cara! Consegui resolver o problema aumentando o limite máximo do upload.

Obrigado!

#86

Pessoa,

Consegui fazer o upload dos arquivos. Porém, quando o sistema vai rodar no servidor de verdade está aparecendo o erro "Permission Denied". O significado obviamente eu sei. Mas como posso solucioná-lo, sem a necessidade de alteração no servidor(Ele não é meu)?

desde já obrigado,

#87

tá dando permission denied aonde? na pasta que vc tá tentando salvar, ou antes de chegar no seu método de upload?

#88

A exception ocorre quando ele tenta salvar na pasta que eu escolhi.

#89

a pasta que você escolheu está sem permissão aparentemente… tenta apontar pra uma pasta que você tem acesso

#90

Na verdade, essa pasta fui eu quem criou, ou seja tenho acesso a ela. :stuck_out_tongue:

porém tem um detalhe. Quando eu pego o ContextPath o resultado é home/login/public_html/fotos. Dessa forma acontece a exception “Permission Denied”.

Se eu escolher o caminho explicitamente, por exemplo, public_html/fotos, aparece uma mensagem informando que não é possível encontrar a pasta. :stuck_out_tongue:

#91

vc precisa colocar o caminho inteiro, começando com / (/home/login/blah)

ou se for uma pasta dentro do servidor vc precisa usar servletContext.getRealPath("/pasta")

#92

Lucas,

O código que eu estou utilizando é este:

                File root = new File(context.getRealPath("/fotos"));
            	
                File dir = new File(root.getCanonicalPath() + File.separator);
                
                IOUtils.copy(imagem.getFile(), new FileOutputStream(new File(root.getCanonicalPath(), imagem.getFileName())));
#93

[quote=malayout]Funcionou.

malayout, tenho uma duvida. Como ficaria a implementação no JSP? Sera que poderia colocar o JSP para eu dar uma olhada?

Obrigado.

			if(arquivo == null) {
				System.out.println("Erro upload");
			}
			else
			{	File destino = new File("c:\\repositorio\\"+arquivo.getFileName());
				destino.createNewFile();
				InputStream stream = arquivo.getFile();
				IOUtils.copy(stream,new FileOutputStream(destino));
				System.out.println("Upload Finish");
			}
			result.include("variable",arquivo.getFileName());

Obrigado pela ajuda.[/quote]
