RE: Socket Server Application Approach

Why not call the RPG program as an external stored procedure? As long as the program doesn't expect data structures, this is very easy to set up. All you have to do is install the .Net data provider on the Windows machine and create the procedure on the i.

Charles,

Writing the socket routines to me is a good lesson in the nuts and bolts
of tcp communications. Scott's tutorial is a tremendous resource and I'm
glad I've had the opportunity to learn from each of his examples. Those
programs (the socket listener and socket instances) are are already coded
and in place. I got all of that done yesterday. Today I'm working on
resolving some of the details...

Regarding web services, that is something I don't have a lot of experience
with (actually none), although I do hope to get there one day.
Troubleshooting and debugging web services could be a bigger problem and
I'm already comfortable with most of the socket stuff so pulling a data
string into an ILE application to do it's thing, to me, seemed to be the
most straight forward approach.

The asp.net application is being written by my network manager and this
removes the burden of my having to do the CGI/CGIDEV portion of the
application. At that point the https connection has already been
established so that is also one less thing for me to be concerned about.
Our i isn't exposed to the internet and the web application will be in the
DMZ.

We're in the early stages of talking about a patient portal application
and perhaps that would be a good use of web services. Since that is still
in the future, I hope to have the time to learn about web services and how
to effectively incorporate them in such a project.

But as always, thanks for the input.

Regards, Jerry
