Probably not a topic for the Seam forum, try the EJB3 forum.
And, as a courtesy to your readers, please try to format you post and code
snippets in more readable way.

HI,
I'd like using this kind of annotation:
@TransactionAttribute(TransactionAttributeType.REQUIRES_NEW).
Consider that I have this situation:
1)I call a first method of ejb3/seam marked with the above annotation.
2)Inside that method I call another method that I want starts in a different
tr
What kind of transaction demarcation/ annotation do you want to use?
Doesn't EJB3 by default already demarcate transaction before and after the
method is invoked?

When you call a method from within a session bean on the same bean, you have to
call it using the interface (if you want transaction attributes to work, and
any other interceptors).
You are probably calling on 'this' at the moment, which means the container
doesn't get a chance to do its magic.
Toni,
I am trying to do exactly what you describe but am having no luck. Could you
possibly give a small example of how you achieved the transactions?
many thanks,
Dustin

Well my last post actually refers not to your last post, but the one before.
What you assume in your last post I thought before and made all the session
beans stateful - but that did not help either.
It's seems to be that on reentrant calls the annotations are ignored. By
introducing another SF
Hi Christian,
thanks for you help. That seems to be the reason.
I introduced another session bean and now its working!

Oh, it's not re-entrant, its sLsb called by sFsb. Anyway, enable logging (no, I
don't search the Wiki for you) and don't guess.

Maybe because it's a re-entrant call? I don't know, ask on the EJB3 forum.

How and where ca I turn this on?
I noticed something very interesing so: I used
"@TransactionAttribute(TransactionAttributeType.NEVER)"
on the first call to the SLSB (stateless) and the transaction gets stopped! In
the logfile I see:
007-05-04 14:56:08,090 ERROR [org.jboss.ejb.txtimer.Timer
You need to enable logging for the transaction service in your server and watch
when transactions are created and when they are committed.

Well thank you for clarifying this! I was already wondering why seam would
introduce an extra transaction annotation, which lacks some of the EJB3
transactional attributes.

So you are saying that "@Transactional" should only be used on Seam components,
which are missing the tags @Stateless or @Stateful?
And that seam components which are tagged with @Stateless or @Stateful should
refer/use "@TransactionAttribute" instead ?

@Transactional is a hint for JavaBeans! It is not used if you have EJB 3.0
components.

As long as there is a persistence context, you can lazy load stuff.
Just use the UserTransaction API or EJB3 transaction annotations to set

Hi,
I'm still trying to figure out how to span several transactions within the
scope of one web request/response.
I guess using a TransactionalSeamPhaseListener is not an option, because it
always starts a transaction at the beginning and end of the request ie response
respectively.
So I gues
Well, I don't think I can use the EJB3 notations in seam. I tried and it does
not work or have any effect.
Trying to acces a user transaction I got:
java.lang.IllegalStateException: Container MessageManager: it is illegal to
inject UserTransaction
So this does not seem to be an option either.
What do you need is user transactions.

Check out @TransactionAttribute in the EJB3 spec.

If you're not using EJB3 Hibernate might have it's own transaction annotations
but I'm not aware of them.
