A stateless session bean cannot access resource managers in a @PostConstruct method.
A stateless session bean cannot access resource managers in @PostCreate().
A stateless session bean cannot access resource managers in @Remove methods.

I agree with 3rd statement, but how can i agree with 1st and 2nd statement's.
There should be no implication accessing in these methods.

[Joe San]

Does the container recognize the @Remove callback for a Stateless session bean?

[Amandeep Singh]

thanks Jothi for your reply. That's why i have mentioned. I understand that 3rd statement is not possible. But why the first and second statement's are true.

Hi Amandeep

From where you have this statements ?

About the PostConstruct -> it occurs after the dependency injection nad I think you have access to the resource manager.
About the PostCreate -> I am not shore if the PostCreate is a standard EJB annotation.

Hi Amandeep,


The question will help me to understand the better the problem, can you send it ?

[Karnati Sudhakar]

A stateless session bean cannot access resource managers in a @PostConstruct method.
A stateless session bean cannot access resource managers in @PostCreate().
A stateless session bean cannot access resource managers in @Remove methods.

4.5.2 section of the specification document should clarify this question a little bit.

Thanks Sudhakar- i should have hesitated to look in Specf.'s first.

Page 88 from core specf.-

PostConstruct, Pre-
Destroy lifecycle callback
interceptor
methods

can have access to these methods SessionContext methods: getBusinessObject,
getEJBHome, getEJBLocal-
Home, getEJBObject,
getEJBLocalObject,getTimerService,
lookup
JNDI access to java:comp/env
EntityManagerFactory access for CMT and SessionContext methods: getBusinessObject,
getEJBHome, getEJBLocal-
Home, getEJBObject,
getEJBLocalObject, getUserTransaction,
getTimerService, lookup
JNDI access to java:comp/env
EntityManagerFactory access for BMT.

If a session bean instance attempts to access a resource manager, an enterprise bean, an entity manager
or entity manager factory, and the access is not allowed, the behavior is undefined by the EJB
architecture.

I got it, for you other guys i will post the question by evening.
