CDI only happening in struts actions

I have one Front-End project that uses Struts calling a Service layer which initially relied on hand made DAO's.
I swapped my DAO for Stateless EJB's
The "debug" pages where some struts actions were directly calling the EJB worked perfectly with @Inject tags.

public class ShowSPAction extends ActionSupport {

	private static final long serialVersionUID = 3182718664721840375L;

	private static final Logger LOG = Logger.getLogger(ShowSPAction.class);

	private List<SP> sps;

	@Inject
	private ServiceProviderDao dao;

	public ShowServiceProviderAction()
	{
		//dao = new ServiceProviderDaoBean();
	}

	public String execute() throws NamingException
	{
		sps = dao.getAll();
		LOG.fatal("List contains : " + sps.size());

		return ActionSupport.SUCCESS;
	}
	public List<SP> getSps() {
		return sps;
	}
	public void setSps(List<SP> sps) {
		this.sps = sps;
	}
}

But similar code (@Inject) does NOT work in the Service Layer which is usually called by Struts.
I was wondering why ... ???
I tried @EJB annotation but NO CAN DO :(

Do I have to make a Separate project for my EJB's ... ?
