I know i should use the session facade but what if my client uses two entity beans client: lets update user A so its calling these two guys: UserEntityEJB { updating user A... } UserInfoEntityEJB { updating user A oppss some exception rolling back but what about UserEntityEJB? how will it roll back ? } so what is happening in that case? whats the use of container managed transactions in that scenario? Thanks In advance, Tomer Back to top Tomer Ben-David Guest Posted: Thu Jul 24, 2003 6:17 am    Post subject: Re: newbie Transactions Thanks, this has completely answered what I wondered about...

If your client calls the entity beans separately then each call will be done in a separate transaction. You should indeed use a facade and from there make the two calls. Or you could invoke update in one entity bean and then have that method invoke the other entity bean's update user method. I hope I have interpreted what you have asked correctly. What you have written is not very precise. Actual methods would have been clearer. Hope this helps.
