Upload imagens Vraptor 4

Estou tenatando criar uma classe de imagens para fazer upload de imagens.

Configurações: Tomcat 8, Vraptor4 e Hibernate.

1 - Criei uma classe de imagens, um construtor recendo servlet context e method de upload.2 - Add todas as dependências exigidas.

Na controller da minha entidade criei a seguinte variável :

@Inject private Imagens imagens;

Aparentemente tudo certo, porém o Vraptor tem apresentado o seguinte erro:

org.apache.tomcat.util.digester.SetPropertiesRule begin
WARNING: [SetPropertiesRule]{Server/Service/Engine/Host/Context} Setting property 'source' to 'org.eclipse.jst.jee.server:ifeventos' did not find a matching property.

A classe Imagens ta anotado com algum escopo? Como está o seu beans.xml? Esse erro tem a ver com o cdi, não necessariamente com o vraptor.

Sim, com @RequestScoped

beans.xml:

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://xmlns.jcp.org/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee 
                            http://xmlns.jcp.org/xml/ns/javaee/beans_1_1.xsd"
    version="1.1" bean-discovery-mode="all">

</beans>

Alberto,

Me desculpe, voltei na documentação e percebi que faltava isso:

O CDI exige que cada classe possua o construtor padrão (sem argumentos). Sendo assim você deverá adicionar o construtor padrão em todos os componentes. E o construtor onde serão injetados os componentes deve possuir a anotação @Inject.

Obrigado.
