Re: RPG to Java Conversion

[MEovino@xxxxxxxxxxxxxxxxx]

Hank,

Just curious, why'd you do the whole thing in one fell swoop?  Why not
build a GUI in either client-side Java (yuck) or JSP/Servlets to get your
users going on the new UI, then replace the business logic?

Did you have business logic mixed with display in your programs?  I hate it
when that happens ;-)

Ken,

I managed a transition of a unemployment tax system from AS/400 to Java and

JSP using DB2 on Linux servers. The most difficult parts of the rewrite
were:
(1) obtaining detailed business rules from the old RPG code, and (2)
communicating to old green screen users about how the new system would work
as opposed
to how they were used to doing business.

On top of this was the expectation from management that Java development
cycle should be much faster than RPG.

Contact me directly for details, as some of them may be too sensitive for a

broadcast.
