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

时间：2011-08-01 22:20:18

标签： java java-ee jsf-2 ejb-3.0 websphere-7

我看到其他thread有类似问题，但无法解决与我的问题的直接关联。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，我们可以使用带有JSF2注释的应用程序，并且只有在我们尝试注入ejb3时才会看到任何问题。来自简单试用版应用的代码如下所示

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;
    }

}

答案 0 :(得分：3)

不考虑使用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。您的选择是：

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

    5. 对于＃4，一个例子是：

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