Hibernate version: 2.1

In an EJB, to roll back a container managed transaction should I use:

A) ctx.setRollbackOnly();
Or
B) tx.rollback();

(tx being a Hibernate Transaction and ctx being a SessionContext.)

The Hibernate API says that tx.rollback() will "Force the underlying transaction to roll back."

But as I'm using CMT, will it really just do ctx.setRollbackOnly() ??

Thanks.

Yes, if you're using CMT, the correct way to rollback is calling ctx.setRollbackOnly.
