從動態Web應用程序調用EJB時遇到問題。我正在使用Eclipse Kepler進行開發。從託管bean調用EJB時出錯
說我有錯誤是，當我調試模式運行應用程序和EJB叫我得到這個錯誤：
沒有其他細節，但如果我看到該選項卡中的錯誤是，我可以看到全文的名稱，EJBLocalObjectInvocationHandlerDelegate.invoke(Ojbect, Mehtod, Object[])
，我用它來調用EJ代碼B是：
@ManagedBean
@SessionScoped
public class UserBean implements Serializable{
@EJB
private UserSessionBeanLocal userSessionBean;
@EJB
private DvdSessionBeanLocal dvdSessionBean;
private int id;
private String username;
private String password;
public UserBean(){
}
public String login(){
String response = null;
userSessionBean.userLogin(username, password);
try {
response = userSessionBean.userLogin(username, password);
} catch (EJBException e) {
response = e.getMessage();
}
return response;
}
編輯：
- 我使用Maven
的pom.xml從客戶層面

我使用Glassfish的4.0作爲我的應用程序服務器
這是堆棧跟蹤，當我運行（未處於調試模式）的應用程序：.jar文件

如何被你的EJB聲明？你使用哪種AS？，你使用Maven/Ant，你的POM看起來如何？ – Sergio
@Chechus對不起，我有點困惑。 AS代表什麼？ –
