Re: Using JAVA for core business logic - Good/Bad?

The way I approach scenarios like this is to realize what the main problem
is. I would guess the shop in question has been successfully developing RPG
apps for some time and are considering Java because of richer UI and easier
to find programmers.

The richer UI is a fairly easy one to address with a variety of either free
(i.e. CGIDEV2, Renasainse Framework) or vendor tools (i.e. RPGsp, RSP,
iSafari, eRPGSDK, Valence, etc). And the vendor tools are very reasonable
in price and keep you in the RPG language (read ROI).

The finding of RPG talent is the tougher one that I don't have a real answer
for. Your options vary from just finding solid programmers in other
languages and getting them to work on the iSeries, to training up your own
computer science college grads.

I find that you can make an iSeries sing sweet love songs if you combine RPG
and Java in a right way for your business. For my purposes I tend to have
much more RPG than Java (i.e. 100 to 1 ratio).

On a final note the one thing I really enjoy about Java is I can write on
three different platforms (phones, printers, desktop, iSeries and web) all
in the same language.

After checking the archives I didn't find what I was looking for to answer
a question I have. Maybe my search was bad as I know the use of JAVA has
been discussed a lot on the list.

I am looking for opinions/reasons, with supporting information, on the use
of JAVA to write business logic instead of RPG on the iSeries. The impetus
for this request is that our architecture group is suggesting that we write
any new business logic in JAVA for portability reasons. Keep our current
application code in RPG, just the new stuff. That's what I have been able
to ascertain to this point. I know it's not much. The general corporate
direction is to move to an SOA architecture with and enterprise service bus
(?) handling the service calls between applications.

In know a lot of people out there either use or have experimented with
using JAVA on the iSeries. What are your thoughts about doing this?
