Generally speaking you are correct. I agree that transaction APIs
should be moved outside of persistence to allow other modules to use
them without needing to use persistence. I have already opened (and
mostly coded) SEAMPERSIST-35 which separates the SeamManaged annotation
from persistence. The annotation was already moved to solder by Stuart
in SOLDER-77. I hope that SEAMPERSIST-35 can be integrated with Final
so that the API calls are clear up front. So I guess what else needs to come out and what does the timeframe look like for post Seam 3.0.0 for a supplemental release? I was targetting May for JCR. To echo George's point, I've seen a few forum posts about JTA dependencies in Seam Persistence, when running it in a tomcat environment. Is it possible for us to do this, while possibly degrading softly when it's not around?<br>

I'd also add that we are using transactions in the Faces module to provide managed transactions integrated into the JSF lifecycle. So again, we see the transaction support used as a top-level feature.<div><br></div><div>

The module could even go a step further and provide simplified transaction configuration for JTA in a standalone environment. I think there is a lot of interesting avenues to explore, which is why having it in a separate module makes a ton of sense. The floor is open for discussion.</div>
