@ejb注入工程，jndi lookup不在Glassfish 3中

Question

我有一個無狀態的ejb。

@Remote 
public interface MyService { 
    ... 
} 

impl 

@Stateless 
public class MyServiceImpl implements MyService { 
    ... 
} 

我有另一個試圖使用MyService的bean，它將通過JMX公開。

@MXBean 
public interface MyJMXBean { 
    ... 
} 

@Singleton 
@Startup 
public class MyJMXBeanImpl implements MyJMXBean { 
    @EJB 
    MyService service; // this works 

    @PostConstruct 
    private void init() { ... } 

    @PreDestroy 
    private void cleanup() { ... } 

    // this doesn't 
    private MyService doLookup() { 
     InitialContext ctx = new InitialContext(); 
     return (MyService) ctx.lookup(MyService.class.getName()); 
    } 
} 

我希望能夠做的MyService的JNDI查找，所以我沒有這方面的規定爲MyService耳朵部署的依賴也。提供MyService和MyJMXBean的耳朵不同，但部署到同一個容器。我得到的例外是：

我不太清楚如何解決ClassNotFoundException的，因爲一切都在裏面Glassfish的運行。

Answer 1

的GlassFish V3支持EJB 3.1和實現爲便攜式全球會話bean JNDI名稱在EJB 3.1如下

java:global[/<app-name>]/<module-name>/<bean-name> 

<bean-name>對應會話bean的EJB名的語法。它默認爲不合格會話bean類的名稱。它可以使用@Stateless/@Stateful/@Singleton註釋的name屬性明確指定。

您在JNDI樹中查找的內容是EJB類的限定名稱。
