我看过其他thread遇到类似的问题，但无法找出与我的问题的直接联系。希望我没有重复问题。我的问题是这样的:
我使用 Webpsphere 7 和 JSF2 作为共享隔离库。
当我尝试将 EJB3 注入(inject)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，它就可以正常工作。然而，如果没有 EJB3 注入(inject)，我们可以使用带有 JSF2 注释的应用程序，并且不会看到任何问题，只有当我们尝试注入(inject) ejb3 时才会出现问题。下面是一个简单试用应用程序的代码
服务接口(interface):
package au.com.test;
import javax.ejb.Local;
@Local
public interface SampleService {
public String getServiceName();
}
服务实现:
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;
}
}

任何人都可以帮我解决这个问题吗？

这些是位于 EAR 内的两个独立模块，部署为 WAS7
最佳答案
不考虑共享库来定位组件定义注释(如@ManagedBean)，因此找不到该组件，这意味着在构建 java:comp 命名空间时找不到其 @EJB。您的选择是:
- 在 WAR 中的 faces-config.xml 中提及 JSF bean。
- 将 JSF bean 放入 WAR 中。
- 在 web.xml 中定义
。 - 在 WAR 中的虚拟“资源生产者”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 { }
关于java - 将 EJB3 注入(inject)基于注释的 JSF2 支持 bean 导致 javax.naming.NameNotFoundException :，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/6905186/
