Re: Passing XML back and forth with RPG and .NET

Both systems will be. Thus the approach I am taking. We don't like the
screen-scraping tools out there and want to avoid using PHP (our knowledge
base is .NET), so I am figuring out a different approach.

I'm a little curious, what system in interacting with the users? The .NET

If so, then just define a fixed record interface between the 400 and the
.NET application, and forget using
XML on the 400. Depsite the vast speed increases that 400's have realized,
you still have a whole lot more
cycles to play with on the .NET side. :)

So let's say you have a .NET webservice defined; the input / output parms
will appear to the web service has arguments.

From there you can simply pack them into any record format your want, open

a socket, and transmit it to the 400. Once the 400
processes it, however you want it to do so, the return from the 400 would
go over the same socket.

The .NET application would then unpack the parms returned from the, set his
local parm variables, and return to the caller.

I use this exact technique to manage some PDFs with thousands of fields in
them. Works great.

(The backend is Linux in my case, but the same idea, and a very trivial
exercise to write. Also cheap. :)

I am at a loss here of a best-practice to pass XML back and forth with

RPG

and C#.NET. Originally, I was going to use a temp physical file in QTEMP,
but it seems to be that there should be a better way. The temp file has

one

line of the document in one record of the file. To me this seems to add a
lot of extra work that really shouldn't be needed. I am looking for a
two-way communication.

One thought is to pass a 32000 char parameter back and forth, but is that
really a good idea? What happens if the document happens to be bigger

than

that? I don't think I would hit that limit so maybe I would be fine?

What about creating a temp IFS file? That seems like more work than is
needed as well.

What are your thoughts?

Obviously, both the RPG and C# programs will be reading and processing

the

XML document.

I have x-post this on systemidotnet as well to get both sides. I hope

David

doesn't mind.
