Non technical advice. :)
Since I've been doing Web applications for some years now, one of the most
enduring processes is educating Users.
Web applications have many benefits as well as drawbacks, the User must
understand the differences and accept them.
You cannot always do what the 3270 terminal application or a client/server
application can do , you can be very very close!
But in the end the most diificult part is getting the User's to change
their habit.
After doing things the same way for 10-15 yrs good luck! Often I take the
time to review with the User the business process.
It is important to do it with the User, this way they get a sense of
creating, participating with the Web application and end up being more
receptive to changes.
In the end, Web applications sort of simplfy the process (as compared to
client/server applications) and ultimately make applications easier to
use.

Subject: JSP / ActionForm / Action design quesetion
Classification:
I'm experimenting with putting a JSP / Struts front-end onto an existing
"green screen" application on a midrange system. I have JavaBeans that
serve as wrappers around the underlying code that implements the business
logic, which allows me to divorce the legacy green screen terminal I/O
interface routines from the business logic. Now, however, I have to meet
a
requirement of the end-user and I'm too new at using Struts and JSPs to
know
for certain how to go about doing meeting the requirement.
In a nutshell, the green screen interface allow for rapid data entry, and
the JSP front-end that I'm trying to build needs to allow for the same
techniques to be used or else it will fail to meet the user's
requirements.
Currently, a lot of of the data that gets entered is for fixed length
fields, and when the data input results in one field being full, the focus
automatically jumps to the next field as if the TAB key had been hit. When
all of the fields of data have been entered, simply hitting the ENTER key
results in the screen full of data fields being submitted, validated and
then the screen is "reset" to empty field values again for additional data
entry. Most of the data is numeric and the data entry is done via the
numeric keypad.
I need to know if it is possible to set up a JSP to work in the same way.
Is it possible to set up a JSP such that quick data entry can be done with
the focus automatically forwarding from one field to the next as the
fields
are filled up with fixed length data w/o having to hit the TAB key and
with
the ENTER key resulting in posting the form data to the applet?
I can already handle the ActionForm programming for data validation and
the
success/failure forwarding so that the successfully validated data is fed
into the model and then the controller forwards back to the same JSP /
ActionForm combination again for additional data entry.
I'm not sure if I can code things so that some other single keystroke can
be
used in place of clicking a "CANCEL" button on the form, such as hitting
the
ESC key and having that trigger an event in the JSP that is the same as
clicking the "CANCEL" button. In the green screen application, hitting
ESC
results in leaving the data entry screen and returning to a higher level
menu. I'd like to preserve as much of the legacy application's quick data
entry functionality while putting a more modern web-enabled frontend onto
the application.
TIA,
Chuck
