[ajug-members] RPG & Java

[Joe Sam Shirah]

    Hi Matthew,

    There are some Java books out there for iSeries/i5 ( we still call it an
AS/400 regardless of IBM's name de jour, ) but they are pretty much directed
at RPG programmers to learn Java.

    Probably the best resource is IBM redbooks

http://www.redbooks.ibm.com/redbooks.nsf/Portals/

but the iSeries ones assume you know something about it.

    I know how this probably sounds, but generally the company is *much*
better off bringing in someone who's been around that particular block and
can speak Java, RPG, and OS/400 with some authority.

    For interfacing Java calls to AS/400 native programs, the Toolbox for
Java/JTOpen has tools that work well.  For RPG or other native programs to
Java, a messaging approach is superior to about anything else.  Here, by
"messaging" I include iSeries native messages, data queues, and standard
MOM's, probably MQ Series.

    One of my clients is looking over Mule ( open source ESB, ) which has an
AS/400 connector; I'm just not sure yet they implemented it properly for
reliability and maintenance.
