我試圖創建一個使用MySQL數據庫在NetBeans一個簡單的Web應用程序。 但是當我運行該應用程序時出現以下錯誤。 我不知道錯誤在說什麼。任何幫助，將不勝感激。錯誤在Java EE的Web APP_的NetBeans

EJB使用管理豆..代碼如下：
package PresentationLayer;
import DataLayer.*;
import LogicLayer.*;
import java.io.Serializable;
import java.util.List;
import javax.ejb.EJB;
import javax.inject.Named;
import javax.enterprise.context.Dependent;
import javax.annotation.PostConstruct;
@Named(value = "placesManagedBean")
@Dependent
public class PlacesManagedBean implements Serializable{
@EJB
private PlacesSessionBean placesSessionBean;
private List<Places> places;
public PlacesManagedBean() {
}
@PostConstruct
public void init()
{places = placesSessionBean.getPlaces();}
public List<Places> getPlaces()
{return places;}
public void setPlaces(List<Places> places)
{this.places = places;}
}
這是EJB注入期間發生的異常。請發佈完整的堆棧跟蹤和執行EJB注入的代碼部分（查找@EJB和類似的註釋）。 –
@MiljenMikic ...我已經添加了應用程序的堆棧跟蹤和託管bean。 – urwaCFC
如果你的'PlacesSessionBean'實現一些遠程接口，那麼你應該改變的聲明爲：'@EJB私人PlacesSessionRemoteInterface placesSessionBean;' –
