Question on pg 196 HFE - NO CMT in ejbcreate

[Shreyas Reddy]

The book says, in ejbCreate method of a stateful bean we cannot call methods to rollback a transaction or find out if transaction has already been set to rollback(CMT)?

But we can get a transaction reference and call method on it...(BMT)

Why is that so?
Is that because we cannot declare the ejbcreate method as CMT in DD?
Thanks,

hi.
in ejbCreate method of a stateful bean, we cannt call to rollback on transaction. but if the stateful session bean implements SessionSynchronization interface, business method can call to rollbak on transaction. additionally, business method of the stateful session bean is called in the "READY STATE". so in the ejbCreate(), you can't call to rollback.
