Re: Future of RPG was: Open Access for RPG

This is very nice, but like most of the frameworks I have seen in either open source or community versions, I think one key element is missing: a bridge for existing 5250 apps.

A web-based framework for menuing, security, and all the gui-ness the users might desire is great. But as soon as you start saying 'open this icon and login and go here for Customer History and open that icon and login and go there for Order Entry, etc' then you have made their lives (and yours) more complicated.

It has been a while since I have played with TN5250j, and there might be other viable replacements by now, but if any of these frameworks had modules like it to handle legacy apps in the transition, then I know more shops would be willing to move.

I personally have played/worked with a few frameworks: Joomla, Dotnetnuke, Renaissance, Valence. I have never really looked at bridging 5250 apps in though, but I have often thought it would be great if they could.

I'm not planning to do it, I have done it (with a litte help from ExtJS)

Of course, if you're planning to build a javascript framework yourself,
you're best choice is to go with plain Javascript.


I was talking about creating an end-user application.

You forgot to mention Open Source projects like jQuery and ExtJS,
with quite a number of millions of users - they are coded in -
OOjavascript.

No DOM has nothing to do with javascript as well as DB2 has
nothing to do with RPG - but both are manipulated by the
programming.

Nobody sane these days programs UI code directly in Javascript.There are

powerful tools such as GWT (develop in Java, deploy in Javascript), or
even EGL CE to do this.

Btw, apart from the DOM (which has nothing to do with Javascript the
language) Javascript is a very neat OO language.For RPG'ers who want to
delve into scripting/browser UI and OO programming it's a good idea to
learn and use Javascript.It's not a difficult language and a fast
turn-around, meaning you get instant reward.It's pure OO, and even has
some "functional" aspects.Just make a simple HTML page, put some
Javascript in it and you can do all kinds of neat things.It's ideal for
trial-and-error learning.
