May be this is the right forum to place my question.
I am trying send product feed to amazon.
Amazon has a service by which we can use SOAP/XML to send product feeds using their API, this will get my product listed in AMazon automatically.
I want to use this automated process.
I am using NUSOAP for sending soap. Amazon said the send the xml as an attachment. I tried to use that to.

But, so far I am unable to do this.
NuSOAP prints out ERROR:Empty returns from Server

The Soap end point I am using

Can any one help me doing this?
I really need an urgent help.
