Criando projeto do 0 usando vraptor 3.5.2[Resolvido]

mvmib · Setembro 19, 2013, 2:57pm

Fala galera … estou querendo migrar minhas aplicações para a versão 3.5.2 do vraptor, mas antes estou criando um projeto do 0 para ver as diferenças, configurações.

Baixei o vraptor-3.5.2-distribution, coloquei todas as libs, criei um controller só para aparecer sucesso em minha jsp mas estou tomando o seguinte erro:

O engraçado é que estou entrando normalmente no método dentro do meu controller. Não sei o que tem que ser feito para essa versão.

Se alguém puder me ajudar eu agradeço.

Abraços,

Marcus.

Posta o código e teu web.xml também.

Essa linha que deu NullPointer é a seguinte:

Pode ser que você não tenha configurado o container IoC. Dê uma olhada no log inteiro da aplicação quando você a subir para ver se não tem algum warning ou mensagem de erro por lá (aproveite e poste pra gente também).

o trace perto da onde aconte o erro. Ve que tem um “Entrei” ali no meio … é um sysout que coloquei para saber que entrei no metodo de fato.

Pra ser sincero eu não achei esse “Entrei” no log não. Posta o código do seu Controller também.

Acabei de achar…heheh…mas mesmo assim posta o código do seu Controller.

mvmib · Setembro 19, 2013, 4:11pm

package br.com.muambei.controller;

import br.com.caelum.vraptor.Path;
import br.com.caelum.vraptor.Resource;

@Resource
@Path(value={""})
public class IndexController {

	@Path(value={"/"})
	public void index() {
		System.out.println("Entrei");
	}
}

Bem simples.

Ataxexe · Setembro 19, 2013, 4:41pm

Eita…se você tirar os @Path o erro continua?

mvmib · Setembro 19, 2013, 4:45pm

Sim …

Não dá erro na hora de subir, mas na hora que acesso a url que ele gera o mesmo erro acontece.

=/

Acho que vou desistir e continuar na versão 3.4.1

mvmib · Setembro 20, 2013, 10:28am

Consegui achar o erro… no distribution que eu baixei, não continham 2 jars que na versão do blank-project tinha … engraçado que no trace não fazia menção a falta desses jars…

eu coloquei e o erro parou de acontecer …

Obrigado pela ajuda.

Ataxexe · Setembro 20, 2013, 10:34am

Ufa, ainda bem que resolveu. Fiquei curioso agora. Quais eram os jars?

alcirBarros · Dezembro 27, 2013, 11:29am

Tive o mesmo problema aqui comprei o livro Vraptor na casa do Código, e a dica do colega “mvmib” funciono o NullPointerException, Sumiu e passou a acessar a jsp.

Conclusão:
Copiar os jar/s do projeto Vraptor-blank para a pasta lib do projeto livraria.
