EJB 3.1 绑定在 Websphere Application Server 上不起作用

【中文标题】EJB 3.1 绑定在 Websphere Application Server 上不起作用【英文标题】：EJB 3.1 Binding does not work on Websphere Application Server 【发布时间】：2014-03-22 23:13:06 【问题描述】：我想从另一个 ejb 项目中的另一个单例 EJB 调用一个本地无状态 EJB。两个 EJB 项目都在同一个 ear 文件中。 Application Server 是 WebSphere Application Server 8.0.0.1。
第一个 EJB 3.1-项目 (PersistenceEJB.jar)：
界面
@Local
public interface TaskInfoDao extends DaoTemplate<TaskInfo>
public int deleteAll();
无状态 Bean：
@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;
ejb-jar.xml 和 ibm-ejb-jar-bnd.xml 为空。
第二个 EJB 3.1-项目（SchedulerEJB.jar）：
单例：
@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());
元信息
Manifest-Version: 1.0
Class-Path: PersistenceEJB.jar
我的“ejb-jar.xml”和“ibm-ejb-jar-bnd.xml”都是空的（在两个项目中）。
ear-文件： -META-INF |-应用程序.xml |-ibm-application-ext.xml |-ibm-applcaiton-bnd.xml |-清单.MF -PersistenceEJB.jar -SchedulerEJB.jar
应用程序.xml：
<?xml version="1.0" encoding="UTF-8"?>

ear META-INF 中的其他文件为空。
在 JVM 启动时出现以下异常：

那么我的代码有什么问题？
提前致谢！
编辑： 当我为我的 startupbean 使用 ibm.websphere.startupservice 接口时，bean 注入工作正常。为了使用这个接口，我删除了@Startup + @Singleton 接口。 我也把我的班级改成了：
public class StartUpBean implements javax.ejb.SessionBean
...
public boolean start() throws FileNotFoundException
...
return true;
还有我的 ejb-jar.xml：
<?xml version="1.0" encoding="UTF-8"?>
<ejb-jar id="ejb-jar_ID" version="3.1" 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/ejb-jar_3_1.xsd">

<ejb-class>ejb.StartUpBean</ejb-class>
<session-type>Stateless</session-type>
<transaction-type>Bean</transaction-type>
</session>
</enterprise-beans>
</ejb-jar>
但我不喜欢这种方式，因为它取决于我使用的应用服务器...
【问题讨论】：
manifest.mf 中的 class-path 行很奇怪；我会删除它。 Web/企业应用程序类路径由容器管理，不要做会干扰它的事情。 我删除了这一行，但我得到了同样的异常... 好，那就排除了。因此，错误是“没有部署此名称的 EJB”；我将假设容器没有说谎。那么 EJB/接口是否存在？类文件物理上是否位于正确的模块中以及部署区域中的正确位置？ 是的，这两个模块都位于 installedApps 的 ear 文件中。这些类也在 *.jar 中可用。 也在application.xml中？ 【参考方案1】：由于 TaskInfoDaoImpl bean 包含在与包含客户端类的模块不同的模块中，请尝试在 @EJB 注释中使用可移植 JNDI 名称，如下所示：
@EJB(name="java:app/PersistenceEJB/TaskInfoDaoImpl")
private TaskInfoDao taskInfoDao;
更多信息here。
【讨论】：
从服务器日志我发现容器首先绑定了调度器（单例）。此时持久化的类没有绑定到服务器。但是容器尝试在单例中注入无状态 bean。这可能是问题吗？ 你试过我的建议了吗？注释应该将 AS 驱动到正确的加载顺序。 行为相同...容器先绑定单例ejb并抛出异常... 听起来很奇怪，这可能是 Websphere 问题，另一种选择是删除 EJB 注释并在单例中的PostConstruct 方法中使用 JNDI 查找创建 bean（用 @Startup 注释它） ，请查看我在回答中建议的链接以获取更多详细信息。以上是关于EJB 3.1 绑定在 Websphere Application Server 上不起作用的主要内容，如果未能解决你的问题，请参考以下文章
