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!

Vern

I may be in the minority here but I'd shy away from using CGIDEV2 for any sort of web development. I say minority on this list only. The percentage of all web developers that have used or heard of CGIDEV2 is probably less than .001%. We've found that RPG developers are hard to find. RPG developers that have web experience are even harder to find. If JSON is a requirement then I'd also be concerned about processing JSON data with RPG. There are plenty of libraries out there for JSON processing but I don't know if you'll find one for RPG.
You could stand up a Linux server running an Apache web server with PHP and connect to your SQL stored procedures on the i fairly easily. There are JSON functions built in to the PHP language. You did not mention Java so I assume that is not an option.
A big consideration for you is the expertise in your organization. That may help drive your decision. If you have access to a lot of RPG developers then CGIDEV2 may be worth a look but keep an eye on the future. That's my biggest hesitation with CGIDEV2.
Thanks,

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 the returned data to be in JSON format. I'm obviously concerned about 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 proprietary...others?
Some products/frameworks that I know of are easy CGIDEV2, Renaissance, Zend, powerEXT..others?
Feel free to contact me off list if desired. I look forward to the comments.
Thanks!
