Re: Atomic batch of webservices calls

[Rajesh Mallah <ma...@gmail.com>]

Hi Victor ,


Sorry for the late reply.

Do you really think it is possible to achieve that?

it is not necessary that all the webservices call be done together.
The subsequent webservice calls may depend on result of previous
ones. Eg consider below pseudocode:

At RPC Client Side:

TXN_UUID = BEGIN TXN;

res = createPartyGroup ( groupName => "foo");
partyId = res.partyId ;
res = createPostalAddress ( address1 => "bar street");
cmId = res.contactMechanismId;
res = createPartyContactMechanism(partyId => partyId , contactMechId=>
cmId);
COMMIT TXN (UUID => TXN_UUID) ;

say any intermediate step fails , then the RPC client sends instruction
to rollback TXN_UUID and expected result is to rollback all changes that
were done in ofbiz side since the beginning of TXN TXN_UUID.

If something like this can be done it opens a host of integration
possibilities
with diverse programming languages and environments.

sincerely
Rajesh.
