javax.ejb.TransactionRolledbackLocalException(Glassfish 3 + JPA + EclipseLink)

Question

我在使用 Glassfish 3.1.2 + JPA + EclipseLink + MySQL 开发的应用程序上遇到问题，在我部署该应用程序后(DB 上没有表)它运行得很好并且显然执行了唯一的查询(Count entities在我输入的表中)。但是如果我重新加载页面，再次调用 servlet 会导致抛出异常:TransactionRolledbackLocalException

显然与用于计算实体的方法相同。

然后如果我再次重新加载，它运行得很好，然后再次异常，正常，异常等等...

这是我的 servlet:

@WebServlet(name="Controller", urlPatterns={"/Controller"})
public class Controller extends HttpServlet {
    private static final long serialVersionUID = 1L;

    @EJB WineDao _wines;

    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {

        _wines.countWines();

        RequestDispatcher view = request.getRequestDispatcher("ShowAll.jsp");
        view.forward(request, response);
    }
} 

这是 WineDao:

@Stateless
public class WineDao {
    @PersistenceContext private EntityManager em;

    public Long countWines() {
        CriteriaBuilder qb = em.getCriteriaBuilder();
        CriteriaQuery<Long> cq = qb.createQuery(Long.class);
        cq.select(qb.count(cq.from(Wine.class)));
        return em.createQuery(cq).getSingleResult();
    }

}

持久性.xml:

    <persistence version="2.0" xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd">

            <!-- log sqls executed in server.log -->
            <property name="eclipselink.logging.level" value="FINE"/>
            <!-- Instruct EclipseLink to not log execeptions it throws. Lets the application decide about it-->
            <property name="eclipselink.logging.exceptions" value="true"/>
        </properties>
    </persistence-unit>
</persistence>

最后是服务器日志，当我没有收到任何错误时:

忘记了 Wine 类:

@Entity
public class Wine {
    public static final int UP_ADDED = 0;
    public static final int UP_REMOVED = 1;
    public static final int UP_PRICE = 2;
    public static final int UP_OFFER = 3;

    @Id Long id; 
    private String name;
    private BigDecimal price;
    private BigDecimal offer;
    @Temporal(TemporalType.TIMESTAMP)
    private Date updateTime;
    private int updateStatus = 0;

    // Getters + Setters
}

我终于找到了解决方案:重新启动 glassfish 域 -.- 经过一天的尝试，这很奇怪。
