WebServicesCore problem

[Todd Ditchendorf]

I suppose it's possible that your server XML-RPC impl is not sending  
a fault string... you need to see the raw XML-RPC response (and  
request too) to see where the problem lies.

Here's what i would do before sending the request:

     // for good measure, make the call follow redirects.
     WSMethodInvocationSetProperty(inv,    kWSHTTPFollowsRedirects,  
kCFBooleanTrue);

     // set debug props
     WSMethodInvocationSetProperty(inv, kWSDebugIncomingBody,      
kCFBooleanTrue);
     WSMethodInvocationSetProperty(inv, kWSDebugIncomingHeaders,  
kCFBooleanTrue);
     WSMethodInvocationSetProperty(inv, kWSDebugOutgoingBody,      
kCFBooleanTrue);
     WSMethodInvocationSetProperty(inv, kWSDebugOutgoingHeaders,  
kCFBooleanTrue);

This will cause it to follow redirects and also include raw req and  
res in the result dicitonary. Print the entire result dictionary to  
see those.


BTW, I just blogged about WebServices Core and HTTP auth (somewhat  
related) the other day on my blog:
