Re: EGL RichUI Was:Re: From RGP to ¿Java?

[Pete Helgren <Pete@xxxxxxxxxx>]

Again, thanks.  Not a bad approach.  In this particular case I have new 
apps to develop so the need to interface EGL and the Java Servlet isn't 
a high priority.

At the core here I have a need to develop about 10 "simple" CRUD apps 
that edit single tables and probably another 10 to 15 that have 1 to 5 
sub-records (header-line).  My original RPG experience in the 5250 world 
used a framework that would allow me to crank out a fully functional, 
edited, CRUD app in about 2 hours.  Header/line models would take maybe 
4-6 hours depending upon complexity. All in all, it was was a pretty 
productive environment (and it wasn't a commercial 3GL either, it was 
just a logically laid out set of RPG/DDS templates that made development 
easy).

I have sought the holy grail of a replacement framework that is both 
cross platform and productive (no need to go into the "why" of cross 
platform, it is just a requirement).  So, I have looked at many 
tools/frameworks/languages and all come up short in one way or another.  
EGL is about as close as you can get.  The web apps are easy to create 
and there certainly are a bunch of widgets that you can take advantage 
of to make the app pretty interactive.

So I stand at the threshold of moving on, finally, to creating these 
apps and RUI is what the users "want".  However, the ease/speed of 
development of an EGL RUI app was a little bit of a disappointment when 
I looked at it so I may fall back to using EGL in a more "traditional" 
way.  I was just hoping to move forward quickly with RUI applications 
for this particular set CRUD apps.

I need to explore EGL RUI one more time before I begin coding.  
Currently waiting for the small update that the update manager is 
installing for RBD 7.5.1.2 (a "mere" 769mb - I'd hate to see what a 
major "point" release would be!)
