[Haskell] haxr (XML RPC server) problems with C# client

[Johannes Waldmann]

Hello.

I am trying to access an haxr (XML RPC) server from a C# client, see
http://www.imn.htwk-leipzig.de/~waldmann/edu/ss06/oo/folien/oo/node153.html
and it does not work: on the client side, I get

Unhandled Exception: CookComputing.XmlRpc.XmlRpcFaultException:
Server returned a fault exception.
in <0x00274> CookComputing.XmlRpc.XmlRpcSerializer:DeserializeResponse 
(System.Xml.XmlDocument xdoc,System.Type returnType)

How do I find out more (e. g. the server's actual response)?

The same server works with a Java client.

Is there a way to have a standalone haxr server,
i. e. a process listening on a port,
without the detour along the web server/cgi mechanism?
(cf. the Java variant)

Thanks,
