This is an issue that was hotly contested when this list first started.  The
JAVA "purists" say don't use the toolkit, as it limits your package to the
AS/400 platform, thus defeating the ultimate purpose of JAVA.  Hard to argue
with that.

I feel that my own approach is more pragmatic, although others will argue the
point.  Having researched several C/S projects, I would choose (given the
time) to write the application in as "open" a manner as possible to start
with, but build in the flexibility to utilize _whatever_ data access method is
most appropriate for your platform of choice.  For example, access the
database with standard JAVA methods in your programs, but build in the ability
to "flip a switch" that tells the application to use JDT methods to
specifically access AS/400 data in order to optimize performance and/or data
integrity.  If you have no plans to run the programs on anything other than an
AS/400, this point is moot.  Then again, if you have no plans to run the
programs on anything other than an AS/400, JAVA itself is moot at this
juncture other than as a career enhancement project...
