將EJB3注入基於Annotation的JSF2引發javax.naming.NameNotFoundException的Backing bean：

我看到其他thread有類似的問題，但無法解決與我的問題的直接鏈接。希望我不會重複一個問題。我的問題是這樣的：
我正在使用Webspphere 7和JSF2作爲共享獨立庫。
當我嘗試在註釋JSF2支持bean注入了EJB3到我得到這個錯誤
將EJB3注入基於Annotation的JSF2引發javax.naming.NameNotFoundException的Backing bean：

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

但是如果我們使用配置JSF2 face.xml，而不是使用註釋它工作正常。但是，如果沒有EJB3注入，我們可以使用帶有JSF2註釋的應用程序，並且只有當我們嘗試注入ejb3時纔會看到任何問題。從一個簡單的試用應用程序代碼如下

服務接口：

package au.com.test; 

import javax.ejb.Local; 

@Local 
public interface SampleService { 
    public String getServiceName(); 
}

服務實現：

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管理的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; 
    } 

}

共享庫不被認爲是用於定位定義組件的註解（如@ManagedBean）的EAR內，所以該組件沒有找到，這意味着在構建java：comp命名空間時找不到它的@EJB。您的選項有：

在WAR中提到faces-config.xml中的JSF bean。
將JSF bean放入WAR中。
在web.xml中定義< ejb-ref>。
在WAR中的虛擬「資源生產者」bean中定義具有註釋的ejb-ref。

對於＃4，示例將是：

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

由於Bkail。 1和3工作。檢查4但是2和4可以請示例WAR中的含義例如HelloBean是一個jsf支持bean並位於C：\ .. \ ibm \ .. \ runtimes \ base_v7 \ profiles \ was70profile1 \ installedApps \ myMachineNode01Cell \ My_Application.ear \ My_Web.war \ WEB-INF \ classes \ helloworld作爲HelloBean.class。 – Shahzeb

如果我選擇選項4，那麼假豆的生命週期如果一個bean加載所有ejbs，將會變得臃腫或性能會受到影響。選項4看起來最乾淨，但也有上述擔憂，因爲上述內容不確定你在戰爭文件中的含義。謝謝 – Shahzeb

有一些JSF MB有一個@EJB註釋。對於＃2，我的意思是將JSF MB放置在WAR中，以便註釋掃描器可以看到它。 –
