Solucionado
O Eclipse está me mostrando a mensagem de erro abaixo na linha do método construtor em que eu faço a injection do objeto Result.
No bean is eligible for injection to the injection point [JSR-346 §5.2.2]
private final Result result;
@Inject
public ProdutoController(Result result) {
this.result = result;
}Estou achando que é um erro do Eclipse, pois tudo está funcionando perfeitamente apesar da mensagem.
Tem algum problema no meu projeto. Agora tentei injetar o EntityManager no ProdutoDao e o Toncat está dando esse erro:
GRAVE: Exception sending context initialized event to listener instance of class [org.jboss.weld.environment.servlet.Listener]

Já descobri qual era o problema. Eu tinha importado o Plugin da JPA que já tem o construtor de EntityManager. Com isso eu tinha que injetar o EntityManager direto nos Daos, sem criar o producer .
