Re: Re: cost estimate for a GUI pilot -- MIDRANGE-L

As far as Spring is concerned, yes it does have a UI, it is called MVC.
Spring also owns a product called Grail which is written in a scripting
language called Groovy which run the Java Virtual Machine. Basically a Java
version of Rails.

The problem I have with Spring and Java and building an application from
scratch is the time and the cost. We built on application and it took us
two years and 2 million dollars on for one application.

Also, have you looked at EGL?

There is an open source version and a paid version supported by IBM. It was
designed originally to provide a web based UI and to be able to call back
end code written in RPG or COBOL which brings me back to using ILE/RPG on
the back end. Build a GUI in EGL and call ILE/RPG service programs through
an interface which provide the business logic.

All this assumes you are planning on new development.

I have appreciated the discussion so far. My company has been deploying
browser user interfaces exclusively since the year 2000, interfacing with
RPG back-end servers. We have deployed hundreds of new applications and GUI
/ PDF reports since then. Virtually none of our software uses display
files.

It is hard to make suggestions about GUI tools without knowing what you
want to do with them, and what you might want the tools to do for you.

Suggesting Profound UI and ASNA Wings implies that you may want to reuse
your existing 5250 logic and workflow, and follow the traditional display
file paradigm. Is that a high priority?

Or, are you more interested in providing the most compelling and productive
user experience possible, taking full advantage of browser capabilities?

Is it more important to cater to your existing RPG skill sets? Or, would
you be more interested in extending your skill sets to include HTML, CSS,
JavaScript - again with the primary goal of providing the most productive
and compelling end-user experience possible?

Are you more interested in facilitating your current skill sets and current
RPG team members? Or would you be interested in bringing in new people who
have GUI design experience primarily with browser technologies, and
teaching them RPG?

Are you more interested in doing a make-over of existing screens? Or, would
you be more interested in restructuring your application architecture to
become more agile and better able to accommodate change?

Are you interested in broadly-scoped application development? Or do you
just have a small project in mind?
