ManagedBean functions not being called

.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ height:90px;width:728px;box-sizing:border-box;
}

I am trying to create a basic datatable which fetches the value from database and displays in the table format. However while I try to debug I see that managed bean functions are not being called. Below is the code

list.xhtml:

<h:body>

    <h3>Expense list</h3>





    <h:dataTable value="#{userMB.entries}" var="e" styleClass="table"

        headerClass="table-header" rowClasses="table-odd-row,table-even-row">



        <h:column>

            <f:facet name="header">Date</f:facet>

            #{e.date}

        </h:column>     

    </h:dataTable>

</h:body>

UserMB.java

@ManagedBean

@SessionScoped

public class UserMB {



    private List<Entry> entries;



    @EJB(mappedName = "entryServices")

    private EntryServices entryServices;



    public UserMB() {



    }



    @PostConstruct

    public void init() {



        FacesContext context = FacesContext.getCurrentInstance();

        HttpServletRequest request = (HttpServletRequest) context

                .getExternalContext().getRequest();

        HttpSession httpSession = request.getSession(false);

        User user = (User) httpSession.getAttribute("user");

        entries = new ArrayList<Entry>();

        entries = entryServices.getEntryByUser(user);

    }



    public List<Entry> getEntries() {

        return entries;

    }



    public void setEntries(List<Entry> entries) {

        this.entries = entries;

    }



    public EntryServices getEntryServices() {

        return entryServices;

    }



    public void setEntryServices(

            EntryServices entryServices) {

        this.entryServices = entryServices;

    }



}

That was a typo when I copied it here, I have corrected it now in the question

If init() was not called, it means the associated managed-bean was not yet constructed. Have you verified the list is not empty ?

there is data in the database, but its not fetching as the function is not being called.

I don't see any error in the code or the facelet, when I use eclipse sometimes I not choose the right packege for the annotation that must be javax.faces.ManagedBean and javax.faces.SessionScoped otherwise the bean is never created.
In glassfish when I use a EJB in the ManagedBean it need to be serialized could you try this.
I hope this could help you.
