ZSI Examples - 002

All..

I'm using stubs generated from the latest (as of  yesterday) ZSI trunk. I need to be able to pass in credentials (user, pass, app name) thru the SOAP headers, so I am passing in a dict as kwargs to my Login() function. Please see attached stubs. Here's how I am calling the stubs, and I get a typecode error:

In [6]: request=LoginSoapIn()

In [7]: loc=SessionServiceLocator()

In [8]: port=loc.getSessionServiceSoap("https://webservices1-2.ihsenergy.com/WebServices/Session")

In [12]: e=[('Username','user'),('Password','pass'),('Application','app')]

In [14]: res=port.Login(request,e)

So I try to set the typecode to Array:

In [20]: request.typecode='Array'

But then I get an attribute error:

Can someone tell me if I am approaching this correctly? Am I sending the credentials for headers correctly into my Login() function as a list of tuples?

And am I setting the typecode properly, and is the typecode for the list of tuples indeed 'Array'?

Thanks
