Answer 1

SERVLET
public class test extends HttpServlet {
   @EJB
   private LocalBean lookupBean;
    protected void processRequest(HttpServletRequest request, HttpServletResponse response)
    throws ServletException, IOException {
        response.setContentType("text/html;charset=UTF-8");
        PrintWriter out = response.getWriter();
  for(Item i : lookupBean.getMyCollection() )
          out.println(i.getItemName());
        out.close();
}BEAN INTERFACE
public interface BeanLocal {
    Collection<Item> getMyCollection();  
}BEAN IMPLEMENTATION
@Stateless()
public class Bean implements BeanLocal {
    @PersistenceContext()  
    private EntityManager em;      
     public Collection<Item> getMyCollection() {
        return em.createQuery("SELECT i from ITEM i").getResultList();
    }    and if you create an instance of your servlet you'll have to reinitialize LocalBean
@EJB(name="myejbref", beanInterface=BeanLocal.class)
private BeanLocal lookupBean;
private BeanLocal getLookupBean() {
if(lookupBean == null) {
try {
InitialContext ic = new InitialContext();
lookupBean = (BeanLocal) ic.lookup("java:comp/env/myejbref");
catch(Exception e){
System.out.println(e.getMessage());
return lookupBean;
}
