Hi rouble

I try to avoid to increase the complexity of my web services based integration 
whereever possible. I don't want to manage the transaction context within web 
service consumers. 

The example you make is a good candidate. You can avoid the situation by a 
proper service design. Design less fine grained operations and instead define 
an operation like "transfer x amount of money from acount y to acount z". 
Deploy your service implementation within tomcat/jee using spring and JTA and 
JPA and you get ACID. Transaction demarcation is on the server side (scales) 
and it is ensured that either the transfer is done or not and your DB is in a 
consistent state.

What do you think?

Thanks

Betreff: How do people implement transactions with CXF?

CXF Gurus, and Users,

How are developers implementing SOAP web services that are
transactional. For instance, if I have a bank web service that does:
api call: debit savings $10
api call: credit checkings $10

I need to be able to begin a transaction before the api calls, and
commit it after. If either one of the apis fails, I need to be able to
rollback.

I understand there are standards such WS-AtomicTransaction,
WS-Coordination and such. But how are people implementing these kinds
of functions in the absence of those standards being implemented in
CXF?

Obviously, one way would be to re-write the above api calls as one api call:
api call: transfter savings checkings $10

But that is not always an option depending on the API.

tia,
rouble
