Hello All,  
I’m trying to figure out how to call a web service from Natural code. The web service is on Windows platform and the Natural code is on UNIX. I think the way to do this at a high level is to:

1. Create an XMM file (IDL-\>XML mapping) using Workbench

2. Start an RCP Server on the Windows machine and configure it to read a location where I put the XMM file

3. Configure Natural to make RPC calls using CALLNAT

I know this is all high level but if someone could just point me to the correct documentation where I could get down to actually what I need to do to make this happen I would appreciate it.

Thanks.
