Generating JSON from an RPG program is quite simple with IceBreak. Minimal
to no learning curve.

The only potential hitch there is generating the JSON data in the HTTP
response with RPG. I know there is JSON functionality that is readily
available in most web development languages. I don't know if there is a
good option for dealing with JSON data in RPG. Rolling your own JSON
library in RPG is not something I'd relish doing.
Thanks,
Todd

I think Todd is saying the same thing I was saying. If you generate your
Web application with client-side technologies (HTML5, JavaScript, jQuery,
etc), and make requests to a server-side program (RPG on IBM i) for JSON
data, the application is much more portable since the user interface is not
being generated by a server-side application. The function of the
server-side program (RPG) is to provide the data in JSON. Much cleaner as
well.

We're talking about 2 different things - jQuery is a client-side
Javascript library while CGIDEV2 is a server-side application. Javascript
libraries can be used with any server application, obviously. You also
lose all portability that way in that only an IBM i system can run your
server-side app. Using PHP allows the flexibility to put your web server
on most any platform. (The back end stays on the IBM i.) That may not be
a concern now but it may be in the future.
Can you create web applications with CGIDEV2? Sure, but I would think
long and hard before going down that road.
Thanks,
Todd

there's no reason you can't use things like jquery when using CGIDEV2 -
the latter is just a way to externalize HTML, similar to how it is done
with DSPFs.
I'm converting to use CGIDEV2 in one of our products. I see it as very
similar in concept to tags as used in PHP or Java.
Again, doesn't JQUery have plugins for JSON?
Just as I said to someone who said about this facelifted interface - I
didn't know you could do that on the iSeries. I said, HTML is just text
- you can do anything!
Same with CGIDEV2 - it's just a streamlined way to put out the text that
comprises HTML.
Just the humble opinion of a newbie to CGIDEV2 and lovin' it!

I may be in the minority here but I'd shy away from using CGIDEV2 forany sort of web development. I say minority on this list only. The

JSON is a requirement then I'd also be concerned about processing JSON

Ok...wide ranging topic I'm sure, but it's Friday. Here's what I'm
looking for...opinions, solutions, ideas regarding web enabling
(browser access) to i applications. A couple of points: The logic on
the i will be written
(re-written) to be accessed by a procedure call. I'm pretty sure I want
security and session state. This application would be for in-house users,
not the public.

I'm thinking three main middleware paths - PHP, CGI, and vendor

Some products/frameworks that I know of are easy CGIDEV2, Renaissance,

Feel free to contact me off list if desired. I look forward to the
