Multiple Web Services, Multiple Data Sources, Single Transaction?

Hi,

I am invoking 2 web services from a client application.

Web Service 1 uses a data source 1 & Web Service 2 uses Data source 2.

I first perform a select + delete operation on Data Source 1 via Web service 1
then i insert the data to Data Source 2 via Web service 2.

Is there any way I can transactional'ize this, so that if anything goes wrong in Insert of Web Service 2, the Delete of Web Service 1 gets rolled back?

Regards,
Pravin
