Thanks , I know it 🙂 But I could find that part in documentation. What differences will it have in comparing to a Natural RPC Server ? ---

are you asking about calling a Natural program vs subprogram? Natural RPC Server is used to make Natural subprograms available, using EntireX as the transport medium and client access/wrapper tool. If you want to make a Natural program available as a web service you need to convert it to a subprogram or use ApplinX to access the data via the terminal interface. ---

I am not an expert in this area and really haven’t done this for myself but from my limited knowledge of the SAG products, you need to develop a web service using a suitable software development tool such as EnitreX WorkBench where you can transform a NATURAL PDA that is callable via RPC to a web service and then publish the service. There maybe other products such as webMethods and I recently heard about “NaturalOne” (Eclipse Style) that could possibly help developing a web service based on a Natural Subprogram working as a back-end server. ---

Yes, NaturalONE can be useful when providing Natural subprograms as web services. There is a tutorial under: [http://www.softwareag.com/NaturalOne/getstarted.html](http://www.softwareag.com/NaturalOne/getstarted.html) The direct link is: [404](http://www.softwareag.com/NaturalOne/tutorials/NaturalONE_HowTo_ProvideWebService.pdf) Regards, Michael ---
