not sure how your java program calls the AS/400 RPG but, maybe you could use the
Java-AS/400 signon and then retrive the user info from AS/400 and store it in
the class called user in your java program. You could then use this user
class to call a program in AS/400 that sets up the authority for other
calls. We did a small prototype with such a user class and it seemed to

AM To: ML - Midrange Email List Subject: Remote Java calls
to RPG AS400 programs ?
I am a very popular person where I work. Please let me explain. My large
company has merged with an even larger company, now this larger company has
via a simplistic prototype program (RPG400) that I put together discovered how
easy it is for them to write Java programs that call (remotely through the IP
network) my tiny RPG400 AS400 programs that then interface with massive legacy
programs that derive information from the workhorse AS400 systems and hand all
kinds of nifty information back to their Java program callers. This larger
company is quite impressed with how this works, and this type of processing is
going to take off where I work.
I hope I explained the scenario well, as I have a few issues:
When the remote Java programs initiate a call to the AS400, the jobs
enter the AS400 as Prestart Jobs in the QUSRWRK subsystem named QRCSRVS
under user QUSER. Why is it under QUSER when the Java programmer actually
uses a different userid to gain access to the AS400 via their Java program?
I actually used the RTVJOBA from the program I wrote in hopes of identifying
the actual caller by their userid, but was perplexed as to only retireve the
If these Java call jobs enter the AS400 under QUSER and not the userid I
assigned to the caller then I lose control of actually limiting a specific
users access, any suggestions?
The Java programmer on the remote side uses a software called (Weblogic
App Server) and this permits him/her to start one or several openings or
portals to the AS400 system which appear as active prestart jobs on the
AS400 system named as above, and then the Java program fires these calls to
my RPG400 interface programs through these openings or portals, so to speak.
So am I right in my description when I say the Weblogic software allows the
Java programmer the ability to create one or multiple openings/portals
remotely to the AS400, these openings/portals appear as active jobs and then
repeatedly call my program through these openings/portals.
What I want to find out from this distinguished group is this:
Is my terminology in the third bullet point above correct, or does my
description sound goofy?
Does anyone have any words of caution or advice or things to be aware of
when doing the process I describe above, as this is going to TAKE OFF big
time where I’m at and I am the alleged 'professional' person that everyone
wants to talk to about this and I still feel like a relative novice?
Please give any advice, I will appreciate all responses.
