Hello,

I’m trying to use my Rails SOAP webservice.  
The scaffolded thing works, but the real SOAP does not.  
Rails is missing the method name.

My client uses some other xml formatting. So I’ve also tried the xml  
request output from the scaffold. But no change.

Do you know what’s wrong?

Rails version is 1.1.6

Below is

1. SOAP client xml try
2. Rails xml try
3. WSDL
