I got a lots of advice, thanks for everybody. 

I did try to clone the exchange rate program and apply to my application. The compilation was OK, but when I executed the program, I got a HTTP 500 Internal service error. Attached is the debug log. The web service is running within our internal network. Can I any suggestion to trouble shoot the problem.

Thanks again.

Henry,

Scott's examples are the best you're going to find.  Giving you more source isn't going to help.

I suggest you take a look at some of Scott's articles on using HTTPAPI.
http://systeminetwork.com/article/rpg-consuming-web-services-httpapi-and-soapui
http://systeminetwork.com/article/report-weather-your-sign-screen
http://systeminetwork.com/article/look-bank-routing-number-rpg
http://systeminetwork.com/article/rpg-can-consume-web-services
http://systeminetwork.com/article/rpg-web-service-consumer
http://systeminetwork.com/article/rpg-web-service-consumer-part-2

Lastly, you may want to look into a companion tool for HTTPAPI called WSDL2RPG.  With it, you don't need to understand XML or web services...

HTH,
Charles
