Re: RPG as Web service

Hi Nathan,

IceBreak does comply with "Web Services" and implements services like SOAP, XML, etc. It is a simple matter to create SOAP, XML, etc. with RPG in IceBreak. It is not limited to the HTTP protocol.

I am not sure what WSDL files are, I've never to used them - I will need to check with the IceBreak manufacturers if this is included in Icebreak. Perhaps if thy are monitoring this thread they can reply!.

Syd

The web service(s) I have created in IceBreak work very well and
very fast ...

I appreciate your endorsement of IceBreak, but it still sounds like you and I are out of sync, regarding what constitutes a web service. And that seems to be a common problem. The term "web service" seems to be applied overly broadly to any process that makes HTTP requests, or generates HTTP responses. But the standards bodies try to limit the term to more specific protocols, using WSDL files, SOAP messages, and XML, etc.

Actually, I don't understand web services protocol that well, myself. I think Aaron Bartell and Scott Klement understand it a lot better than I, for example. Perhaps like you, I'm much more familiar with HTTP protocol, where data is exchanged using little more than &name=value pairs, and prefaced by HTTP request or response headers.

For the sake of this discussion, I'd suggest that we stick to web services that implement WSDL, SOAP, XML, specifications, etc. Does IceBreak generate or consume WSDL files, for example? Have the folks who created IceBreak written anything to consume Web services?

Nathan.
