In general, it is advised to do access to resource manager ( access to enterprise beans) only in transaction context.

If so why is the above allowed in ejbCreate(), ejbremove() methods stateful beans ? However the operations are not allowed in afterCompletion() method. Why ?
[ejbCreate,ejbRemove and afterCompletion do not have a txn context in case of CMT]

Further the operations are not allowed in ejbCreate()/ejbRemove() methods of stateless beans. Why ? ( The user context is not available in the case of statless beans. But you can still access the resource managers without an user context)

Thanks in advance for the clarifications.

Dear Sankar,

CMT session bean methods ejbCreate(),ejbRemove(),ejbPassivate(),ejbActivate() runs in an "Unspecified Transaction Context". and are not considered a part of client transaction.
page 499. HFEJB
may be this clears your doubt......i am not quite sure.
