HFE Page 497 - Transaction Question

Q.
Of the six transaction attributes, which one (or ones) must NOT be used by
a bean that calls getRollbackOnly() or setRollbackOnly()?


I was think of Supported, NotSupported and Never, but the answer in HFE site says "Never"

Hi Mini,
Yes, I think you are right. Because Supports, NotSupported or Never should not be used by beans that call getRollbackOnly() and setRollbackOnly(). If the beans try to use any of those attributes, the container will definitely throw IllegalStateException.

Hope this helps.

Hi Mini:
I did not see the answer HFE site but I choosed the same answers like you did, Supports, NotSupported and Never. I think those three are the answers unless one gives me reasons to think otherwise.
