[Pywebsvcs-talk] building a webservice wsdl first

[Otu E. <o.e...@gm...>]

Hi,
I would appreciate it if anyone could help.
I have the following wsdl and have generated the files for it using the
commands shown below.

wsdl2py -b -t TYPES -f examples.wsdl
wsdl2dispatch -f examples.wsdl

I am however recieving SOAP Faults when I send messages to the server.
My TYPES.py file is attached.

I am simply trying to echo a string back to the client.
Client side support for webservices in ZSI is pretty good but the server
side is suffering IMHO.

I'd appreciate any help.

Thanks.
