jaikiran pai commented on JBAS-9424:
------------------------------------

Please try against latest AS6 nightly build http://community.jboss.org/thread/161386. Also if that doesn't work, then please try using @EJB instead of @Inject.

>             Project: Legacy JBoss Application Server 6 
>          Issue Type: Bug
>      Security Level: Public(Everyone can see) 
>          Components: EJB, Weld/CDI
>    Affects Versions: 6.0.0.Final
>         Environment: All (*NIX, Mac-Os-X and Win)

> I recently noticed a very strange behaviour (with JBOSS AS 6) with Message-Driven-Beans where we inject EJB.
> If the JMS queue is empty when the jboss server is started, then everything works fine.
> If, no luck, the jms queue is *NOT* empty, my MDB is apparently mounted *BEFORE* the ejb's
> and the @Inject failed:
> => "Failure WELD-000079 Could not find the EJB in JNDI:  class xxx"
> I further investigated the problem:
> I replaced the @Inject annotation, with a "manual" lookup of my ejb 
> using the javax.enterprise.inject.spi.BeanManager capabilities (that i put in a @Postcontruct method of my MDB), 
> The trick consisted in trying the lookup n times with a delay of x sec between each attempt.
> Here are the results (excerpt from server.log):

> => the 6th attempt now works :-)
> {code} 
> Conclusion: according to me, there is no doubt: dependencies between MDB's and EJB's are not correctly managed by the app server.
> The app server should wait for all EJB's to be bound before activating the MDB.
> MDB are activated too early (especially when jms queue is not empty at starttime)
