Thanks. I just got off a conference call with the developers, and nobody
could answer the question "What are you trying to accomplish?" All I got was
"We were told to do this by the principal architect".

They decided to get him on a call tomorrow when I asked, "If he told you to
jump into a river full of crocodiles, would you do it?"

Stay tuned.

Subject: Re: IBM i and Java

Figured this is a good one for me to chime in on.
Java runs very well on IBM i these days. The versions of Java we on on
IBM i these days is a version that is created by IBM vs Oracle. Since
its
IBM created, we have gone to great lengths to really exploit the Power
processor. Once you get to the world of Power 7 & Power 8, Java runs
very
well on these processors due to the high degree of multi threading built
in to these processors. So, yes Java runs well on IBM i.
Now, is it a candidate for 'modern' applications ? The real answer is
'it
depends'. What are you trying to accomplish ? Java is very good at many
things for sure. But, depending on what your program is trying to
accomplish Java may work, but in most cases, it is going to 'cost' you
more in memory and CPU usage. Is that a problem ? again, it depends.
The RPG language is amazing for certain applications, and due to the
nature of the language, its incredibly thin when it comes to memory usage
and database interactions. Now, RPG does fall down just s tad when it
comes to the UI and certainly Java is fine option.
Also, for a while, Java was really the only alternative for doing a more
modern UI for a number of years. While that was fine for some, for many,
that was not a great alternative. Today on IBM i, we have a wealth of
options available. Java, Python, Node.js, Php, and several others.
If you want the latest info on Java for IBM i, check the developer Works
Web Site for Java on i.

Since I can't remember the last time I saw IBM promoting Java, what would
you folks say to developers who want to replace a green screen
application
with code written in Java.

(You'd be dumbfounded by the memory and disk spikes caused by their index
building.)

I have seen Java run on IBM i very effectively. It's not a bad solution.
