----------------------------------------
Thanks Amita:
I will try my best.
I would like to vote on the DataSourceTM, because with DAS in fact, we controll the DataSource/Connection by our self (by the caller object). I think what we expect is the container managed TM.
The DASTM will actually paly like what you mentioned in your picture. If there is no change to the DAS itself.
Since we have proxy for any component inside Tuscany, why not use it for our goal?
::Let the proxy begin the transaction(at top of the invoke), intercept exceptions out from those components it refer, and roll back the transaction. If no exception occured, the proxy (at top) will commit the transaction.
During this process, any nested component/proxy should judge itself wether it is inside a parent transaction, if it dose, it should not start its own transaction.

Sequence of my suggested container managed transaction (local only).
The proxy at top of the invocation handles every thing.

----------------------------------------
My transaction management is at a "very low level", it means any component inside a transaction could get and use the java.sql.Connection instance directly (through the static method TransactionInfo.getConnection).
But infact, programmer is likely using high level presisience technologies such as JPA or Hibernate. All of them could get supported (extended) on the basis of my design.

Hi Amita and every one:
I would like contribute 3 java and a modification on the JavaImplementationInvoker.java
These are my initial design for the on fly Tuscany's local transaction management.
I wish they could be favored to add to your picture.
There are comments inside the java files, they explain things in detail.

Amita Vadhavkar commented on TUSCANY-1803:
------------------------------------------
this looks great. Will you please elaborate a bit about the difference in roles of DataSourceTM and DASTM? Also, it is really helpful if you can contribute to this.
May be you can ML this JIRA link to tuscany-user+dev and get the feedback from people.
Regards,
Amita
