Не инжектится ejb

Здравствуйте, у меня есть сервлет который работает и все отображает. Он примерно такой

@WebServlet("/test")
public class MyServlet extends HttpServlet {
    @Override
    protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
        PrintWriter writer = resp.getWriter();
        writer.print("hello world");
        writer.close();
    }
}

Я перехожу по ссылке: http://localhost:8080/test и вижу hello world

В другом пакете я создал такой Ejb:

import javax.ejb.*;
    @Stateless
    public class HelloWorldBean {
        public String sayHello() {
            return "hello";
        }
    }

Меняю код в сервлете, делаю его таким:

import javax.ejb.*;
@WebServlet("/test")
public class MyServlet extends HttpServlet {
    @EJB
    HelloWorldBean worldBean;
    @Override
    protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
        PrintWriter writer = resp.getWriter();
        writer.print(  worldBean.sayHello());
        writer.close();
    }
}

перехожу на http://localhost:8080/test и имею следующее :
