[jboss-user] [EJB 3.0] - @PreDestroy and injected JavaBeans

[beligum]

Hi all,

I'm trying to do the following:


  | @Stateful
  | @Scope(SESSION)
  | @Name("outboxManager")
  | public class OutboxManagerImpl extends AbstractManagerImpl implements OutboxManager, Serializable
  | {
  |     private Map<Principal, List<EmailMessage>> queuedMessages;
  |     
  |     @In(create=true)
  |     private EmailMessenger emailMessenger;
  | 
  |     [constructors, getters, setters, ...]
  | 
  |     @PreDestroy
  |     public void cleanup()
  |     {
  | 	try {
  | 	    sendAllQueuedMessages();
  | 	} catch (EmailException e) {
  | 	    e.printStackTrace();
  | 	}
  |     }
  |     @Remove
  |     @Destroy
  |     public void destroy()
  |     {
  |     }
  | }
  | 

Everything works fine, but when the @PreDestroy method is called, the injected JavaBean (POJO with @Name("emailMessenger")) has become null. I tried to re-inject it manually, but some other initialization-things (eg. the email renderer) go wrong then.

Am I missing the point here that the injected values are already irrevocably destroyed when @PreDestroy is reached/called, or is this expected behavior? If so, how do I send my queued mails when the session goes out of scope?

thanks a lot,

b.
