vc precisa mexer no multipartConfig como está no final dessa página:
http://vraptor.caelum.com.br/pt/docs/download-e-upload/

e vc tá usando o plugin do gae?

#3

estou usando o plugin do GAE sim, inclusive fiz deploy da aplicação para testar outra classe.

quando vc diz em mecher no multipartConfig quer dizer criar essa classe?

@Component
@ApplicationScoped
public class CustomMultipartConfig extends DefaultMultipartConfig {

public long getSizeLimit() {
    return 50 * 1024 * 1024; // 50MB
}

}

sou leigo no assunto e nunca tinha mexido com upload, vlw

#4

sim, algo nessa linha…

o plugin do GAE teoricamente desabilita a criação de um arquivo temporario para o upload… vc registrou o pacote do plugin no web.xml?

#5

consegui, estava esquecendo algumas libs, obrigado pelas dicas.
