EJB 3.1綁定在Websphere Application Server上不起作用

我想從另一個ejb項目中的另一個單例EJB調用ejb項目中的本地Stateless-EJB。兩個EJB項目都在同一個ear文件中。 Application Server是一個WebSphere Application Server 8.0.0.1。EJB 3.1綁定在Websphere Application Server上不起作用

首先EJB 3.1-項目（PersistenceEJB.jar）：

接口

@Local 
public interface TaskInfoDao extends DaoTemplate<TaskInfo> { 
    public int deleteAll(); 
}

無狀態豆：

@Stateless 
@TransactionAttribute(TransactionAttributeType.REQUIRED) 
public class TaskInfoDaoImpl implements TaskInfoDao { 
    private static final long serialVersionUID = 1L; 

    @PersistenceContext(unitName = "MyDatasource") 
    private EntityManager em; 

    @Override 
    public int deleteAll() { 
     Query query = em.createQuery("DELETE FROM TaskInfo t"); 
     int count = query.executeUpdate(); 
     return count; 
    } 

}

的ejb-jar.xml和IBM-EJB-JAR -bnd.xml是空的。

二EJB 3.1項目（SchedulerEJB.jar）：

辛格爾頓：

@Startup 
@Singleton 
public class StartUpBean { 
    private final static Logger LOGGER = Logger.getLogger(StartUpBean.class 
      .getName()); 

    @EJB 
    private TaskInfoDao taskInfoDao; 

    @PostConstruct 
    public void onStart() { 
     LOGGER.info("DELETED: " + taskInfoDao.deleteAll()); 
    } 
}

META-INF

Manifest-Version: 1.0 
Class-Path: PersistenceEJB.jar

我「ejb-jar.xml中」和「IBM- ejb-jar-bnd.xml「爲空（在兩個項目中）。

耳文件： -META-INF | -application.xml | -IBM-應用ext.xml | -IBM-applcaiton-bnd.xml | -MANIFEST.MF -PersistenceEJB.jar -SchedulerEJB.jar

的application.xml：

<?xml version="1.0" encoding="UTF-8"?> 
<application id="Application_ID" version="6" 
    xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/application_6.xsd"> 
    <description>...</description> 
    <display-name>SchedulerAppEAR</display-name> 
    <module id="Module_1392974920540"> 
     <ejb>SchedulerEJB.jar</ejb> 
    </module> 
    <module id="Module_1392975196627"> 
     <ejb>PersistenceEJB.jar</ejb> 
    </module> 
</application>

其他文件在耳META-INF是空的。

在JVM的啓動，我得到以下異常：

所以什麼錯我的代碼？

在此先感謝！

編輯： 當我爲我的startupbean使用ibm.websphere.startupservice接口時，bean注入工作正常。要使用此接口，我刪除了@Startup + @ Singleton接口。此外，我改變了我的類爲：

public class StartUpBean implements javax.ejb.SessionBean { 
... 
public boolean start() throws FileNotFoundException { 
    ... 
    return true; 
} 
}

我的ejb-jar.xml中：

但我不喜歡這種方式，因爲這取決於我使用的應用程序服務器上...

manifest.mf中的類路徑行很奇怪;我會刪除它。 Web /企業應用程序類路徑由容器管理，不要做可能會干擾的事情。 – Gimby

我刪除了這一行，但我得到相同的例外... – veote

好，那是排除然後。所以，錯誤是「沒有部署這個名字的EJB」;我會假設容器沒有躺着。 EJB /接口是否也存在？類文件是否物理地位於正確的模塊中並位於部署區域的正確位置？ – Gimby

由於TaskInfoDaoImpl Bean包含在與包含客戶機類的模塊不同的模塊中，因此請嘗試在@EJB註釋中使用便攜式JNDI名稱，如下所示：

@EJB(name="java:app/PersistenceEJB/TaskInfoDaoImpl") 
private TaskInfoDao taskInfoDao;

從服務器日誌中，我發現容器首先綁定調度器（單例）。此時，持久性類不綁定到服務器。但容器試圖在單例中注入無狀態bean。這可能是問題嗎？ – veote

你有沒有試過我的建議？ annotatin應該驅動AS適當的加載順序。 – remigio

相同的行爲...容器結合的單身EJB第一和拋出異常... – veote

EJB 3.1綁定在Websphere Application Server上不起作用
