ruby soap client without wsdl

Question

Hi,

I need to write a soap client that is capable of sending and receiving soap messages.

This soap service does not have an associated WSDL file and soap4r and savon both seem to require one.

I have an example of what I need to do in Java, see the link below.

I could use java for this, at this point it seems like it would be easier. However I personally prefer coding in ruby and our company has more ruby resources than java.

Can anyone confirm thats its possible to do something similar to java example in ruby without writing my own specialised soap library?. I need to be able to send a payload, which I believe is usually in the form of a soap attachment.

I am particularly interested in seeing soap4r examples that don't use a WSDL as I have had trouble finding any with google.

Any help much appreciated.
