Thx for your answer
Yes shure it works for small things like communication with a Hello World passing a string an receiving somehting.
The webservice i have to connect to offers several services with a lot of objects to serialize and pass through. So my favorite way would be a good wsdl2obejctive-c with a soap framework...
My last option would be to write all the objects by hand and setup all the needed soap messages by hand...
