Steve,
We have been doing Web Services for about 7 years now. After a lot of trial and error we have settled on using WDSC or the Rational Toolset to do publish web services. If you have WDSC 7.0 or Rational Developer for I (IBM did a name change again surprised?), you have the tools needed. We have chosen two different methods to do this.
1. WDSC web services creation wizard - Use Remote Systems Explorer to run the wizard against an existing RPG source file. You can run the web services creation wizard. Your entry parms will become the data that is exchanged with the service.
2. Learn EGL - IBM has a free EGL Community edition to use or you can use the trial version that runs for 60 days. EGL is a good route to go as well but the learning curve is steeper.
Pros of solution 1 - Quicker time to develop. Not as much of a learning curve. Any RPG program with output parms can become a web service.
Cons of solution 1 - Array limits in RPG. If you have to return a lot of data RPG will hinder you.
Pros of solution 2 - No array limits. EGL handles the arrays not RPG.
Cons of solution 2 - Steeper learning curve. EGL (separate licensing is needed)
I'd suggest you take solution 1 if you don't have to deal with a lot of data.
After using both I favor solution 2. Our other web services developer favors solution 1.
Both solutions will publish to WebSphere Application Server. We haven't tried to publish to Tomcat but that probably could be done. Either way an EAR file will be generated to be run by the web server.
Best Regards,
Tim Swearingen

After reviewing the presentation "Consuming Web Services from RPG using
HTTPAPI", I need to learn more about publishing (or providing) a Web Service
using HTTPAPI/RPG, how is this different from "consuming" and/or what, if
any, API's are provided for this?
Please advise.
Thanks in advance.

Well...
1) HTTPAPI doesn't come into play when publishing a web service
2) You need to be running a web server
3) You need to output a document instead of reading it
4) The CGIDEV2 toolset is one possibility

HTTPAPI is a client application only. It does not provide (or
"publish") web services. It can only consume them.
IBM provides several very nice free tools for providing web services on
i. Personally, I suggest you start with the Integrated Web Services
(IWS) tool. There's a simple example, and links to documentation here:
http://systeminetwork.com/article/ibms-integrated-web-services
IWS also provides a tool for consuming web services, but I don't
recommend that tool unless you're very good with pointers and C-style
code. So if you want to consume, stick with HTTPAPI (maybe with
WSDL2RPG) and if you want to provide, try IWS.

You can create a webservice using CGIDEV2 but not the conventional ones
though. You can implement the logic of webservice implemented through
CGIDEV2.
