    /** Creates a new instance of LoginController */
    public LoginController() {
        user = new IUser();

        if (userBean.userLogin(user.getUsername(), user.getPassword()) != null) {
           if(user.getUsername() != null || user.getPassword() != null){
               user = userBean.userLogin(user.getUsername(), user.getPassword());
               if(user.getGroups().getAdmin() != null){
                    setAdmin(user.getGroups().getAdmin());

               }
               if(user.getGroups().getMods() != null){
                    setMod(user.getGroups().getMods());
                }
               if(isAdmin() == true || isMod() == true){

                    return "home";

               }else{
                return "login";

    }

}

my question is when i use method isAdmin from loginController for userController to check if he is admin he can choose user groups, if he isn't admin he add default groups is member. but isAdmin from loginController return false why? why it not still data when user login?

You need to inject the bean as a managed property.

@ManagedProperty(value="#{loginController}")
private LoginController loginController;

And get rid of the new LoginController() line in the constructor. It would construct a completely separate instance of the bean, not reuse the already-created one in the session scope.
