RE: Ice cream

I don't profess to be a Web expert but a webfaced application is published a Websphere server and runs as any other internet application I think it' much more than a screen scraper. It provides the UI you're looking for and maintains the business logic built into your existing green screen applications.

Hi Booth,

To me, the crux of your question seems to be how to approach modernization of your applications. In the most traditional sense, you're needing to know how best to separate your business logic from your UI...

There are probably as many opinions on this subject as on any "hot topic", but I still feel that building your business logic into modules and service programs is the most beneficial way to start here...

When I hear "event driven", I think of the user-facing elements. The UI needs to operate in event-driven fashion, because that helps to product a pleasant and responsive user experience. Below the UI, calls to your service programs then conduct your transactions.

Hth,

Thank you for the suggestion. I appreciate it.

I am hoping for a parallel but unrelated solution. Webfacing is screen-scraping, I believe? That, in my opinion, is a kludge and not event driven, which is a real limitation of any 5250-based solution. I am trying to open up a simple pathway to a true event-based solution.

You could write the application as a 5250 green screen app and then webface it.

Subject: Ice cream

I am not sure if this request is in the right forum, or even if it is on-topic, but here goes.

I like to do demonstrations/examples of basic techniques on my website.
Anyone who has visited www.martinvt.com/ knows the stuff is pretty simple stuff. It has been in my mind for some time to do a demo of a simple Intranet application that does various things with a simple
physical file. After several false starts, confusion, and missteps, I
realize that this simple idea is still too complex for my current understanding.

My intention is to have a dual-sided application: do the tasks both
with 5250 green screen and with a browser application. Lets say I have
a physical file of flavors of ice cream with a link to an image of the item. I wish to add/update/delete to the file, and do a couple or reports from the file, including displaying the image in the browser.
All on an i.

I have lots of questions, but probably the first question should be: Is there already an example out there somewhere that I should look at? The second question is: Am I tilting at windmills? Is this a foolish idea with no useful purpose? Third, is this something that is of interest to average RPG programmers?
