Mmmm... Interesting
HATS is apparently a Specialized Server that runs under Websphere with
the function of emulating IBM terminals connected to a legacy system
and interfacing them to a network or the web.
http://www-3.ibm.com/software/webservers/hats/about.html
It is not clear if there is any way [for a CF program] to participate
in the emulation process.
However, HATS outputs HTML and accepts HTML as input,
I assume that you could build a front end using CFHTTP.
HATS offers some GUI options, but likely much less sophisticated than
available with CF Flash.
I could envision using HATS to provide basic emulation -- GreenScreen
Terminal to GreenScreen HTML, with no added features. Then , write a
CF/Flash app to provide the GUI that the user actually sees thru
Datascraping/Harvesting with CFHTTP.
This would allow some very interesting possibilities, such as adding
capabilities (eg. logging, lookup UPS charges, spell checking, etc.) in
the CF portion that are not present in the legacy app.
Another task that is more common than you might think, is interfacing
one legacy app with a different legacy app on a different server-- for
example, when one two companies merge, but have not, yet, combined
their IT systems -- accounting, purchasing, inventory. This situation
often exists for years.
A CF app could act as the broker between these separate systems and as
by-products provide a common interface with: integrated searches,
reporting, etc., on multiple systems that are *not* actually
integrated.
There can be quite a synergy, with this approach!
Say Fox and CBS merge -- you can write CF apps that allow mgmt to have
integrated access, reporting and control to key legacy apps without
needing to rewrite or integrate those systems -- at a savings of
millions of $ and many man years of effort.
Since IBM markets Websphere, HATS and CFMXJ2EE, it may be possible that
they can all play nicely together with a more formal interface than
Datascraping/Harvesting.
