using XA (distributed) transactions with local DB and web se

[asookazian]

We have a use case to be implemented in my Seam 2.x app which requires an insert tx to a local DB and a client call to a remote web service for insert tx to another remote DB.

Using an SFSB or SLSB component in my Seam app, how would I be able to achieve XA/2PC in this scenario (if it's even possible?) thx.

Assume CMT plz.

Should I simply catch SoapException and any RuntimeException and the EJB container will automatically rollback the global/distributed tx?
