CDI将EJB注入到Glassfish v3上的POJO中

Question

是否可以使用Glassfish v3上的CDI将EJB 3.1 bean注入POJO？

我的类(在EJB模块中):

@Singleton
@LocalBean
@Startup
@Named
public class NewSingletonBean {

    @PostConstruct
    public void init(){
        System.out.println("NewSingletonBean INIT");
    }

}

_

@Singleton
@LocalBean
@Startup
@DependsOn(value="NewSingletonBean")
public class NewSingletonBean2 {

    @Inject NewSingletonBean newSingletonBean;

    @PostConstruct
    public void init(){
        System.out.println("NewSingletonBean2 INIT");
        System.out.println("EJB injected into EJB: " + (newSingletonBean != null));
        MyPOJO p = new MyPOJO();
        p.sth();
    }

}

_

public class MyPOJO {
        @Inject NewSingletonBean newSingletonBean;

        public void sth(){
            System.out.println("EJB injected into POJO: " + (newSingletonBean != null));
        }
}

服务器输出:

注意行:

INFO: EJB injected into POJO: false

所以看起来@Inject成为EJB工作正常,但进入POJO却没有.我究竟做错了什么？我试过GlassFish 3.1和3.0.1(使用NetBeans 7.0.1).

编辑:我正在使用NetBeans 7.0.1.dist目录结构:

?   CDITest.ear
?
????gfdeploy
    ????CDITest
        ????CDITest-ejb_jar
        ?   ?   .netbeans_automatic_build
        ?   ?   .netbeans_update_resources
        ?   ?
        ?   ????META-INF
        ?   ?       beans.xml
        ?   ?       MANIFEST.MF
        ?   ?
        ?   ????tries
        ?           MyPOJO.class
        ?           NewSingletonBean.class
        ?           NewSingletonBean2.class
        ?
        ????CDITest-war_war
        ?   ?   index.jsp
        ?   ?
        ?   ????META-INF
        ?   ?       MANIFEST.MF
        ?   ?
        ?   ????WEB-INF
        ?       ????classes
        ?               .netbeans_automatic_build
        ?               .netbeans_update_resources
        ?
        ????META-INF
                MANIFEST.MF

未包装的EAR结构:

?   CDITest-ejb.jar
?   CDITest-war.war
?
????META-INF
        MANIFEST.MF

解压缩的EJB模块jar结构:

????META-INF
?       beans.xml
?       MANIFEST.MF
?
????tries
        MyPOJO.class
        NewSingletonBean.class
        NewSingletonBean2.class

我对CDI不是很熟悉,但我想如果你自己创建POJO对象,就不会发生注入.你试过了吗:

@Inject
private MyPOJO p;

代替:

MyPOJO p = new MyPOJO();  

？
