Re: Replacing a Web Service with RPG... -- RPG400-L

        It occurred to me that it might be possible to set up an RPG program
listening on an internal port and just suck the message in and manually
parse it,  produce a reply and send it.  I immediately thought about Scott's
HTTPAPI, but I was unsure if the httpapi had any facility for doing that.
It seems that all of the api's require a URL for gets/posts and it isn't
obvious to me how to set that up or if this is even true.

Are you running the server side or the client side? From what I can makeout from your description, you're actually running the SERVER. HTTPAPI(and Brad's GetURI, as well) are client-side tools. They take on the rolethat would more traditionally be handled by a web browser. They do nottake on the role of the web server.

For a web server, you could use a tool like CGIDEV2. Though, for parsingXML input, it might make more sense to call QtmhRdStin() directly, sinceCGIDEV2 doesn't understand XML.

You could then feed the input to an XML parser (such as Expat, or IBM'stool) to get the data you need from the SOAP message, and use CGIDEV2 toreturn the results.

I guess I could just write a socket program listening to aninternal port that I have a reverse proxy in apache pointing to... ?

I guess? I haven't worked with Apache's proxies, so I'm not sure if thatwould benefit you at all.

I've written some articles on Web programming from RPG that you might findinteresting (these require a membership to the iSeries Network, but a free"Associate" membership will work:)

I've also written some material on parsing XML with Expat. You candownload the code from my Web site, there are also links there to iSeriesNetwork articles that explain the code (which also require an associateor better membership)
