Re: Best webifier for green screen applications

While in general I agree I have seen many really well implemented “scraped” 5250 apps that are keyboard driven - have auto-complete - convert options to dynamically driven pulldowns etc. In a similar vein, I have seen some truly awful web applications that were “designed” from the ground up.

Sometimes you have to do the best job you can with the resources you have.

Personally I would stay away from things like HATS because, as others have stated, they are basically a dead end. On the other hand the “scraper” products from companies like Profound, look, BCD, Rocket, etc. can evolve into the development of “ground up” web applications.

We’d all like to have the budget and time to “do it right” from the ground up, but the reality is that we seldom get that opportunity.

I've always considered HATS to be a "stepping stone technology" and not a

Call it "stepping-stone", "interim", "stop-gap", "make-shift",
"provisional", or whatever. Each of those terms is being overly generous to
every screen-scraping product out there. Transforming 5250 streams into
browser DOM objects makes the UI worse - not better, IMHO. You're adding
something like 30-100 times more CPU overhead, something like 20 times more
bandwidth, and reducing the productivity of end-users.

I'm not OP and I don't know the context of the request, but I can
sympathise. Imagine getting a decree from the corner office that the
company Shall Be Browser Based in 6 months. How would I do that, having
never once deployed a mission critical app to the web? I can argue with
the new CIO all I want, but he's new, he's making his mark in the world
and I'm a dinosaur in his eyes.

I might be making that a little too personal :-/

ps I utterly agree that a webified 5250 application is hideous compared
to a web app that was conceived, designed, implemented, and deployed as
a web app from the start.
