Thanks for ypu reply!
What you must be right if the developer who writes the  client  and  the
server is the same.
If i want to connect to a service written by another developer i don't understand
how I can write my client code without wsdl file that describe the service.
How can i know methods and parameters exposed?How can i write stub classes
with nothin in my hands?
I thought these things could be possible ONLY having wsdl file. If there
is another way plese tell me how can i do?
Thanks a lot
