If your company is considering of keeping existing RPG programs instead of
rewriting everything in Java, then you can consider of using Program Call
Wizard which comes with WDSCi. This wizard generates Java beans which can
call any ILE or OPM programs remotely on iSeries, including RPG programs.
You don't even have to learn Toolbox for Java or JNI. If you have the
source of these RPG programs, you can just import the source into the
wizard, and it generates the Java bean for you easily. Alternatively, you
can have ILE RPG compiler to generate PCML, and then import the PCML into
the wizard. I am sure you will find this wizard useful if you just want to
call RPG programs from Java.

Please respond to
Websphere
Development
Studio Client for
iSeries
Thanks a lot Charles. That solves my 'Hello World' problem, I surmise.:-).
Well, this is the situation...I am a Java programmer and there ours is a
pure AS400 shops where lots of programs are written in RPG and we are
moving
towards Java and we will be going through a translation project in a year
or
so and in the mean time I need to understand RPG so that when those
programs
get converted into Java I need to understand the Logic behind those RPG
programs so as to make sure that no garbage is coming out into Java
classes.
Well, please let me know if that gives you any idea of the problem I am
in...if not I will be glad to elaborate. Thanks a bunch for the response.
Mike.
