Atomic batch of webservices calls

[Rajesh Mallah]

Hi ,

Is it possible to execute a set of  data modifying webservices using XML-RPC
in a all-or-none manner.

How complicated will it be to modify the code / or develop new code
to have such a feature.

Hi Rajesh,

I believe that an option that you might want to consider is to use a proxy
like approach intended to create a custom service at OFBiz side which would
call the target services as a part of an atomic transaction, I know that
could not fit for all use cases anyways could work for you.

Kind Regards,
Victor

Hi Rajesh,

I'm not quite sure of you need. You mean that you want to dynamically modify OFBiz exported services in XML-RPC format using OFBiz data?

By "modify" I mean modify services behaviours.

I guess you know that you can't use a modified service without restarting OFBiz.

Please clarify, thanks

Jacques

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.
