将EJB3注入基于注释的JSF2 Backing bean导致javax.naming.NameNotFoundException：

我已经看到其他线程有类似的问题，但无法解决与我的问题的直接链接。 希望我不是在重复一个问题。我的问题是：
我使用带有JSF2的Webpsphere 7作为共享隔离库。
当我尝试将EJB3注入带注释的JSF2支持bean时，我得到了这个错误

Caused by: javax.naming.NameNotFoundException: Name comp/env/helloworld.HelloBean not found in context "java:". 

但是如果我们使用face.xml配置JSF2而不使用注释，它可以正常工作。 但是，如果没有EJB3注入，我们可以将应用程序与JSF2注释一起使用，并且只有在我们尝试注入ejb3时才会看到任何问题。 下面是一个简单的试用应用程序的代码

服务界面：

 package au.com.test; import javax.ejb.Local; @Local public interface SampleService { public String getServiceName(); } 

服务实施：

 package au.com.test; import javax.ejb.Stateless; import javax.ejb.TransactionAttribute; import javax.ejb.TransactionAttributeType; @Stateless @TransactionAttribute (TransactionAttributeType.NOT_SUPPORTED) public class SampleSession implements SampleService { @Override public String getServiceName() { return "Sample Service"; } } 

JSF托管bean：

 package helloworld; import java.io.Serializable; import javax.ejb.EJB; import javax.faces.bean.ManagedBean; import javax.faces.bean.SessionScoped; import au.com.example.service.SampleService; @ManagedBean @SessionScoped public class HelloBean implements Serializable { /** * */ private static final long serialVersionUID = 1L; private String name; @EJB private SampleService sampleService; public String getName() { return sampleService.getServiceName()+ name; } public void setName(String name) { this.name = name; } }

谁能帮我这个 。

UPDATE
这些是位于EAR内部的两个独立模块，可以部署WAS7

Answer 1

不考虑共享库来定位组件定义注释（如@ManagedBean），因此找不到组件，这意味着在构建java：comp命名空间时找不到它的@EJB。 你的选择是：

1. 在WAR中的faces-config.xml中提到JSF bean。
2. 将JSF bean放在WAR中。
3. 在web.xml中定义。
4. 在WAR中的虚拟“资源生成器”bean中使用注释定义ejb-ref。

对于＃4，一个例子是：

 @ManagedBean @EJBs({ @EJB(name="helloworld.HelloBean", type=SampleService.class) // ... etc }) public class ResourceProducerBean { }
