Hi, sorry about the delay.
I've looked at the Taverna source code in question, and it seems that
unfortunately the library Axis 1 (which Taverna uses for calling SOAP
services) is expecting a reply, and thus does not understand one-way
WSDLs.
I can put this into our issue tracker, but I'm afraid there won't be
any immediate fixes ready unless we patch Axis or move on to an
alternative way to invoke web services.
Is this your service? Are you able to make the service return a simple
status code or something..? Currently the service does not even allow
the reporting of any errors.
