NPE primefaces's orderlist on a dedicated server with glassfish, work fine on localhost

Question

I launch my web application on localhost via netbeans on a glassfish server. I have no error on the page rankMe.xhtml. The deploy of the .war on my dedicated server work fine. But when I try to access to the page rankMe.xhtml with a primefaces orderlist, I have an NPE error.I don't get it.

java.lang.NullPointerException

I don't think the code of my xhtml page is necessary but just in case :

In rankMe.xhtml :

<p:orderList value="#{waitingList.recupererWL()}" var="player" controlsLocation="none"  
                                    itemLabel="#{player}" itemValue="#{player}" id="basicList"/>

In the CDI bean waitingList :

@Named
@RequestScoped
public class WaitingList implements Serializable {

    public WaitingList() {
    }

    public List<String> recupererWL() {
                ArrayList<String> players = (ArrayList<String>) FacesContext.getCurrentInstance().getExternalContext().getApplicationMap().get("players");
                if (players == null) {
                    players = new ArrayList<String>();
                    FacesContext.getCurrentInstance().getExternalContext().getApplicationMap().put("players", players);
                }
                return players;
    }

Thanks for reading

EDIT : I checked if it was the good .war deployed.So it's not this kind of problem

EDIT2 : Generally, what/where should I look when I have no error on localHost and error on dedicated server ?

EDIT3 : I also notice other stuff do not work. In my opinion , the CDI bean are not create.

Answer 1

I just restart the domain and it work. Well not perfectly, the list are put in an horizontal way, growl do not have any icon.

Great : X

EDIT : I just realize glassfish need something like 512 RAM minimum, but 1G is better. My remote server actually have only 512 RAM so this is probably the cause of all my problems.
