I'm trying to build up some XML-RPC based services. I was reading through the documentation [1] where its mentioned that xmlrpc_foo() functions in the server can return Failure objects to indicate errors.

The XML-RPC spec uses a slightly different terminology of Faults. The xmlrpclib in Python's standard library also talks about being able to return Fault objects in case of errors.

I was wondering how this is dealt with in Twisted. Fault objects have explicit faultCode and faultString parameters. I couldn't determine if and how these map to attributes of a Failure object.

I remember doing a hack regarding this in the past. Now that I take a closer look at it though, it seems that you only have to raise a xmlrpclib.Fault(faultCode,faultString) in your errback for it to behave properly. /Simon
