NPE primefaces'；使用glassfish在专用服务器上创建订单列表，在本地主机上运行良好

我通过glassfish服务器上的netbeans在本地主机上启动web应用程序。我在rankMe.xhtml页面上没有错误。 在我的专用服务器上部署.war工作正常。但是当我试图使用primefaces orderlist访问页面

rankMe.xhtml

时，我遇到了一个NPE错误，我不明白

java.lang.NullPointerException

我不认为我的xhtml页面的代码是必要的，只是以防万一：

在rankMe.xhtml中：

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

在CDI bean等待列表中：

@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;
    }

@Named
@请求范围
公共类WaitingList实现了可序列化{
公共等待列表（）{
}
公开名单{
ArrayList players=（ArrayList）FacesContext.getCurrentInstance（）.getExternalContext（）.getApplicationMap（）.get（“播放器”）；
if（players==null）{
players=newarraylist（）；
FacesContext.getCurrentInstance（）.getExternalContext（）.getApplicationMap（）.put（“玩家”，玩家）；
}
返回球员；
}

谢谢你的阅读

编辑：我检查了它是否是好的。战争部署。所以它不是这样的问题

EDIT2：一般来说，当我在本地主机上没有错误，在专用服务器上没有错误时，我应该看什么/哪里

EDIT3：我还注意到其他东西不起作用。在我看来，CDIBean不是创建的。

我只是重新启动了域，它就工作了。不是很完美，列表是水平放置的，咆哮没有任何图标

好的：X

编辑：我刚刚意识到glassfish需要最小512 RAM，但1G更好。我的远程服务器实际上只有512 RAM，所以这可能是我所有问题的原因。

发布完整堆栈跟踪。我的web浏览器页面上没有更多的。我还有组件树和作用域变量，你需要它们吗？我正在查看日志glassfish服务器的文件，但我没有找到此错误。
