When CMT bean commit?

[Hong Anderson]

I understand that commit/rollback of CMT bean is called by container. I think CMT bean call rollback() when system exception occur or setRollbackOnly() was called, but when CMT bean call commit()?

A CMT bean must never call the commit or rollback methods, it is the container which ends transactions.

I understand bean never call commit/rollback, but my question is when the container commit transaction.

As mandated by the EJB spec, a stateless session bean and a message-driven bean must commit a transaction before a business method returns.
