Boa tarde pessoal!

Estou tendo dificuldades em solucionar um erro:

Galera fiz o context.xml na pasta META-INF

<Context>
<Resource
name="BeanManager"
auth="Container"
type="javax.enterprise.inject.spi.BeanManager"
factory="org.jboss.weld.resources.ManagerObjectFactory"/>
</Context>

Essas são as configurações. Se alguém já solucionou esse tipo de erro.

Oi joelson123

Até onde eu utilizei o CDI, eu sempre criei uma interface para uma determinada classe que eu precisaria injetar.

No que eu vi, você tem uma classe DAO sendo que deveria ter uma Interface, pois o CDI (Weld) pega a sua interface e criar um objeto encapsulando a sua classe que implementa a interface, isso em tempo de execução.

Modifique a estrutura do seu sistema para

interface DAO > class DAOImpl > e no DAOFactory, você retorna a interface, mas cria o DAOImpl.

E onde for utilizar, o dao, você deveria ter um @Inject para a classe que precisa.
