Re: Call Java program from RPGLE -- JAVA400-L

HTTPAPI is open source (http://www.scottklement.com/httpapi/), RPG-XML
is a for fee product (http://www.rpg-xml.com/). AFAIK, HTTPAPI doesn't
provide a web service, but it's good for consuming a web service.
RPG-XML is good for providing a web service. Both are quality
products.

We do. We use Scott's HTTP-API to consume both internal and external web
services... and it is the only portion of the whole shebang that doesn't
break :)
