Hi Maxime,
please change the WSDL as follows:
where you are defining the message parts (<wsdl:part name=“SessionID”) you need to use “element=” instead of “type=”.
Additionally your WSDL is not compliant to the WS-I Basic profile as rpc/encoded is not defined there.
Only document/literal and rpc/literal are defined in WS-I Basic profile.
Here is nice overview fo the different wsdl styles with explananations:
