Ejb3 session bean lookup

Question

Hello, I have following problem with the ejb3 and session bean lookup:
For example, I have a session bean with some dummy method, i.e. getInfo() :
@Stateless
public class MySessionBean implements MySessionLocal {
public String getInfo() {return "Hello from Session bean";}
When I lookup and use this bean in servlet in the following way, everything is OK:
public class MyServlet extends HttpServlet {
@EJB() MySessionLocal mySession;
protected void doPost(HttpServletRequest request, HttpServletResponse response) {
out.println(mySession.getInfo());
On the other side, when I create some java bean object as a facade, import and use it in servlet , it doesn't work:
public class Facade {
@EJB() MySessionLocal mySession;
public String getInfo() { return mySession.getInfo();}
public class MyServlet extends HttpServlet {
protected void doPost(HttpServletRequest request, HttpServletResponse response) {
Facade myFacade = new Facade();
out.println(myFacade.getInfo());
When servlet runs and gets to the command myFacade.getInfo(), NullPointerException is thrown, because mySession object in myFacade is null (ejb lookup method probably fails to perform...)
I'm trying to use Facade to be able to use my Session Bean in JSP pages, i.e. to do something like <jsp:useBean id="myFacade" class="Facade" ...>
Could someone clarify why lookup doesn't work in javabean object, despite the fact that it works in servlets?
P.S. I'm running the latest promoted build (b31) of GlassFish (maybe this is the cause) and NetBeans IDE...
