RE: IBM i and Java

["Paul Nelson" <nelsonp@xxxxxxxxxxxxx>]

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.

   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.
