Is this statement true? I read it in EJB3 in action(page 201, section 6.3.4)
If you are using a stateful session bean and need to maintain a transaction across method calls, BMT is your only option.
I was under the impression that CMT could do this too.

If you don't want client-app(s) to control the transaction boundary by using the UserTransaction, then BMT is the only way to maintain transaction
across method calls
