javax.ejb.EJBException：javax.ejb.CreateException：無法創建無狀態的EJB

我找到了一些同名的文章。不幸的是，我找不到任何解決方案來解決我的錯誤。javax.ejb.EJBException：javax.ejb.CreateException：無法創建無狀態的EJB

我是JEE，JSF，EJB的新手。我正在使用Netbeans 7.0.1。我遵循本指南：http://wiki.netbeans.org/DevelopJavaEE6App。

這就是： CustomerSessionBean：

@Stateless 
@LocalBean 
public class CustomerSessionBean { 

@PersistenceContext 
private EntityManager em; 
@Resource(name = "jms/NotificationQueue") 
private Queue notificationQueue; 
@Resource(name = "jms/NotificationQueueFactory") 
private ConnectionFactory notificationQueueFactory; 

public List<Customer> retrieve() { 
    Query query = em.createNamedQuery("Customer.findAll"); 
    return query.getResultList(); 
} 

public Customer update(Customer customer) { 
    Customer updated = em.merge(customer); 
    try { 
     sendJMSMessageToNotificationQueue(updated); 
    } catch (JMSException ex) { 
     Logger.getLogger(CustomerSessionBean.class.getName()).log(Level.SEVERE, null, ex); 
    } 
    System.out.println("Customer updated in CustomerSessionBean!"); 
    return updated; 
} 

private Message createJMSMessageForjmsNotificationQueue(Session session, Object messageData) throws JMSException { 

    ObjectMessage tm = session.createObjectMessage(); 
    tm.setObject((Serializable) messageData); 
    return tm; 
} 

private void sendJMSMessageToNotificationQueue(Object messageData) throws JMSException { 
    Connection connection = null; 
    Session session = null; 
    try { 
     connection = notificationQueueFactory.createConnection(); 
     session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE); 
     MessageProducer messageProducer = session.createProducer(notificationQueue); 
     messageProducer.send(createJMSMessageForjmsNotificationQueue(session, messageData)); 
    } finally { 
     if (session != null) { 
      try { 
       session.close(); 
      } catch (JMSException e) { 
       Logger.getLogger(this.getClass().getName()).log(Level.WARNING, "Cannot close session", e); 
      } 
     } 
     if (connection != null) { 
      connection.close(); 
     } 
    } 
} 

public List<DiscountCode> getDiscountCodes() { 
    Query q = em.createNamedQuery("DiscountCode.findAll"); 
    return q.getResultList(); 
} 
}

我得到這個錯誤：「javax.ejb.EJBException異常：javax.ejb.CreateException：無法創建無狀態EJB」我每次訪問一個JSF頁面時（在指南：CustomerList.jsp; CustomerDetails.jsp）如果我不評論「@Resource（name =」jms/NotificationQueue「）」。如果我評論它，jsf頁面將顯示。

的JMS目的地jms/NotificationQueue通常需要被創建。指南的確沒有提到它。

也許Netbeans嚮導自動爲您創建它，並且您還沒有通過嚮導創建MDB？

編輯：

的指南並提到它：

In the New Message-Driven Bean dialog, specify the EJB Name as NotificationBean and the package as "com.customerapp.mdb", click on the "Add..." button of the Project Destination option

In the Add Message Destination dialog, specify the Destination Name as NotificationQueue and keep the Destination Type as Queue and click OK

這讓嚮導創建一個glassfish-resources.xml文件，它定義了隊列：

<resources> 
    <admin-object-resource enabled="true" jndi-name="jms/NotificationQueue" res-type="javax.jms.Queue" res-adapter="jmsra"> 
     <property name="Name" value="PhysicalQueue"/> 
    </admin-object-resource> 
    <connector-connection-pool name="jms/NotificationQueueFactoryPool" connection-definition-name="javax.jms.QueueConnectionFactory" resource-adapter-name="jmsra"/> 
    <connector-resource enabled="true" jndi-name="jms/NotificationQueueFactory" pool-name="jms/NotificationQueueFactoryPool" /> 
</resources>

如果你沒有關注的對於這封信和/或不使用Glassfish的指南，您必須自己定義它（請注意，每個Java EE實現都有不同的語法）。

謝謝你回答我，嗯..我使用NetBeans嚮導創建NotificationBean（按照Netbeans指南）。我在管理控制檯中檢查了Glassfish，創建了JMS目標jms/NotificationQueue。 – hainp

您可能想要嘗試刪除嚮導在EJB模塊中創建的不必要的xml文件：轉到Files視圖，然後轉到CustomerApp-ejb - > src - > conf並刪除清單和glassfish-ejb.xml文件（只有peristence.xml應該保留）。特別是glassfish-ejb.xml是完全沒有必要的（因爲EJB已經註釋了），在這種情況下實際上可能是有害的。 – akira

p.s.我也很快跟上了指南，而且這裏工作起來。 – akira

與GlassFish ejb-jar.xml中和清潔&構建的刪除幫助我的情況下（Netbeans的7.1.1，3.1.2的GlassFish）
