E ai Galera.
Estou com um grande problema, estou desenvolvento uma aplicação onde eu separei as entidades, dao, repository e todas as regras de negocios em um projeto CORE e nesse projeto
estou utilizando CDI(Weld) em várias partes do meu codigo como a criação do EntityManager, e dos DAO por exemplo,
e possuo um outro projeto web onde estou utilizando VRaptor na versão 3.4, mais no momento que recebo como dependencia no contrutor do meu controller um
objeto que esta nesse projeto CORE e lançada uma Exception do Spring mesmo eu colocando a anotação @Component do VRaptor nesse objeto que esta sendo injetado.
Preciso de uma ajuda para resolver esse problema.
Valew…
Eu fiz utilizando o plugin de cdi do Vraptor…
Mais estou recebendo a seguinte exception

Adicione o pacote br.com.caelum.vraptor.plugin.cdi no seu web.xml assim:
br.com.caelum.vraptor.packages
br.com.caelum.vraptor.plugin.cdi
O plugin deve ter sido registrado automaticamente. Então se você desativou o scanner, precisa declarar manualmente.
Coloquei o o pacote do plugin no web.xml e agora estou recebendo a seguinte exception:

Você precisa ler as mensagens e interpretá-las 
Classe não encontrada, imagino que o jar não esteja indo no deploy.
Otavio desculpa por não observar o erro corretamente.
Agora verifiquei e a dependencia esta sendo colocada no deploy, mais estou recebendo outra exception
pelo o que eu consegui observar o erro esta acontecendo na seguinte classe.

OBs… Esqueci de comentar estou realizando os testes no Tomcat 7 :roll:
Você tem um beans.xml vazio dentro do META-INF? É necessário ter ele para ativar o CDI.
Em um projeto Maven os arquivos beans.xml e context.xml
tem que ficar na seguinte estrutura:
webapp/META-INF/context.xml
ou em alguma outra?
Desculpe, META-INF é para projetos EJB. Para um projeto web o beans.xml deve ficar em WEB-INF/beans.xml. Em um projeto Maven fica em src/main/webapp/WEB-INF.
Coloquei no WEB-INF e mesmo assim nao funcionou. O arquivo context.xml utilizado para habilitar o CDI no Tomcat tem que ficar em qual estrutura?
Confirme se você fez todos os passos para habilitar o CDI no tomcat.
Depois crie um servlet qualquer, e injete algum bean seu neste servlet usando o @Inject. Se funcionar é porque está habilitado o CDI.
