postgresql – Glassfish 4和Postgres ConnectionPool上的JSF 2.

我的应用程序基于使用Postgres 9.2 DB的Glassfish 4上的JSF 2.2 EJB 3 JPA.我在Glassfish上创建了一个ConnectionPool和Datasource,我通过相关的Datasource JNDI名称在我的应用程序中使用它.
我有两个Facelets页面：

> login.xhtml调用BackingBean LoginBacking,它调用UserManagement EJB上的登录方法,该方法使用JPA持久性单元检查登录.在这种情况下一切正常,用户能够登录,并且在电子邮件已经存在的情况下,系统通知用户他已经注册.
> registration.xhtml调用BackingBean RegistrationBacking,它调用UserManagement EJB上的register方法,该方法使用JPA持久性单元将用户持久保存到DB中.注册不起作用！通过查看Glassfish日志,我发现以下异常：

我的实体和托管Bean类：

@Entity
@Table(name = "momuser")
@Named

@XmlRootElement
public class MomUser implements Serializable {
private static final long serialVersionUID = 1L;
@Id
@GeneratedValue(strategy = GenerationType.SEQUENCE,generator = "user_seq_gen")

// Getters and Setters

在EJB方法下面：

@Override
public void registerUser(MomUser user) throws UserExistsException {
    try {
        user.setPassword(generateMD5Hash(user.getPassword()));
        em.persist(user);
    } catch (UnsupportedEncodingException | NoSuchAlgorithmException ex) {
        Logger.getLogger(MomUserManager.class.getName()).log(Level.SEVERE,null,ex);
    }
}

Backing bean方法：

public String register(){
    try {
        MomUser currentMomUser = (MomUser) evaluateEL("#{momUser}",MomUser.class);
        MomUser momUser = userManager.getUser(currentMomUser.getEmail());
        if (momUser != null) {
            getContext().addMessage(null,new FacesMessage(EMAIL_ALREADY_EXISTS));
            return null;
        }
        try {
            userManager.registerUser(currentMomUser);
        } catch (UserExistsException ex) {
            Logger.getLogger(RegistrationBacking.class.getName()).log(Level.SEVERE,ex);
            getContext().addMessage(null,new FacesMessage(EMAIL_ALREADY_EXISTS));
            return null;
        }
    } catch (Exception ex) {
        Logger.getLogger(RegistrationBacking.class.getName()).log(Level.SEVERE,ex);
        getContext().addMessage(null,new FacesMessage(SYSTEM_ERROR));
        return null;            
    }

    return "login";
}

并注册Facelet：

你有什么主意吗？为什么我能登录但我无法注册新用户？
