are you activating the mutator for userName?
usually onSubmit or onClick or onChange will activate the mutator for userName with something like #{userManager.setUserName('fubar')}"
to set the userName Value
glassfish contains a sample called UniversalClient which has accessors and mutators for all the attributes of the bean (including userName)

>
> Hi guys,
>
> I have a couple of jsf pages (composed using facelets). In the header part of the template I want to display "Login" if the user is not logged in yet and "Logout" if the user is logged in.
>
> What I did so far was to create a backing bean as follows:
>
> [i]@Named
> @SessionScoped
> public class UserManager implements Serializable {
> private @EJB UserService userService;
> private User user;
>
> public User getUser() {
> if (user == null) {
> Principal principal = FacesContext.getCurrentInstance().getExternalContext().getUserPrincipal();
> if (principal != null) {
> user = userService.getUserByName(principal.getName()); // Find User by j_username.
> }
> }
> return user;
> }
>
> public String getUserName() {
> getUser();
> if(user==null){
> return "Guest";
> }else{
> return getUser().getFirstName()+" "+getUser().getLastName();
> }
> }
>
> public String logout(){
> HttpSession session = (HttpSession)FacesContext.getCurrentInstance().getExternalContext().getSession(false);
> if(session!=null){
> session.invalidate();
> }
> return "index";
> }
>
> public boolean isAuthenticated(){
> return getUser()!=null;
> }
> }
> [/i]
>
> The important part in the header looks as follows:
>
> [i]<h:outputText value="Welcome #{userManager.getUserName()}!"
> rendered="#{userManager.isAuthenticated()}"/>
>
> <h:outputLink value="login.xhtml"
> rendered="#{!userManager.isAuthenticated()}">
> Login
> </h:outputLink>
>
> <h:outputLink value="#{userManager.logout()}"
> rendered="#{userManager.isAuthenticated()}">
> Logout
> </h:outputLink>
> [/i]
>
> The problem is that, even if I successfully login in the first page, when I get to the second page it looks like I'm not logged in. And indeed, while debugging, I noticed that the "user" field does not keep its value.
>
> Can anybody suggest what am I doing wrong ?
