How are transactions managed for web services

Hi,
How are transactions managed when publishing stored procedures as web
services? Does SQLXML automatically commit the transaction if the stored
procedure succeeded and rollback if it failed?
Thanks.

For SQL Server 2005 using SOAP endpoints: Nope. Layering a Web Service on
top of a stored proc doesn't change how the stored proc behaves, you still
need to manage the transactions correctly and internally to your own code.
The new TRY-CATCH syntax makes that easier, of course.
Thank you,

opportunity to manage the transactions directly so I am presuming that
SQLXML does it automatically.

support for cross-service call transactions. If you want to build such a
system, you will have to build your own multi-level transaction management
scheme.

absolutely ideal and music to my ears. I just wanted to confirm that this
was so before pressing ahead with a large project.
