仓廪实则知礼节，衣食足则知荣辱。这篇文章主要讲述EJB 3.1绑定在Websphere Application Server上不起作用相关的知识，希望能为你提供帮助。
我想从另一个ejb项目中的另一个singleton-EJB调用ejb项目中的本地Stateless-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-Project（PersistenceEJB.jar）：
接口
@Local
public interface TaskInfoDao extends DaoTemplate<
TaskInfo>
{
public int deleteAll();
}
无国籍豆：
@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;
}}
ejb-jar.xml和ibm-ejb-jar-bnd.xml为空。
第二个EJB 3.1-Project（SchedulerEJB.jar）：
辛格尔顿：
@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
我的“ejb-jar.xml”和“ibm-ejb-jar-bnd.xml”是空的（在两个项目中）。
ear-File：-META-INF | -application.xml | -ibm-application-ext.xml | -ibm-applcaiton-bnd.xml | -MANIFEST.MF -PersistenceEJB.jar -SchedulerEJB.jar
application.xml中：
<
?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"

【EJB 3.1绑定在Websphere Application Server上不起作用】耳朵META-INF中的其他文件是空的。
在JVM-Startup上，我得到以下异常：

那我的代码怎么了？
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。要使用此接口，我删除了@Startup + @ Singleton接口。我也改变了我的课程：
public class StartUpBean implements javax.ejb.SessionBean {
...
public boolean start() throws FileNotFoundException {
...
return true;
}
}
我的ejb-jar.xml：

但我不喜欢这种方式，因为它取决于我使用的应用程序服务器...
答案由于
TaskInfoDaoImpl bean包含在与包含客户端类的模块不同的模块中，因此请尝试在@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;
