ActionWebService: XMLRPC Server Multicall possible?

Hi all,
I have a question concerning ActionWebService XMLRPC servers: Is it
possible to send multicall requests to the Web service? I tried to
use multicall and get the error message:
no such method ‘system.multicall’ on API [MyAPI]

In Changeset 2021 there is the following commit message:
add ‘system.multicall’ support to XML-RPC. boxcarred methods must
still exist
on the target service(s), value casting will still be performed, and
recursive
‘system.multicall’ calls are not allowed.

Any hints what I can do to enable multicalls in my Rails application?

best regards,
Holger

Thank you very much for your help.

multicall should be enabled by default. Show me how you call it, please.

Can you check log files at the server side? Are there any exceptions
logged?

Hm, strange. How do you register your api with a controller? What
web_service_dispatching_mode are you using?

In my app/apis/ directory I have got a file called oms_api.rb where
the api is defined.
web_service_dispatching_mode is default ( I did not change it). So I
think direct dispatching is used.
All functions who should be usable by oms webservice are listed in
the api file.
In app/controllers/oms_controller.rb all the functions of the web
service are defined.

I have
wsdl_service_name ‘Oms’
web_service_api OmsApi
in my oms_controller.

Do I have to specify the system.multicall function in my oms api?
