Ejb is not injected

Hello, I have a servlet that works and displays everything. He's about

@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(); } } 

I follow the link: http: // localhost: 8080 / test and see hello world

In another package, I created this Ejb:

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

I am changing the servlet code, doing it like this:

 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(); } } 

I switch to http: // localhost: 8080 / test and have the following:
