Re: Call Java program from RPGLE

Scott's HTTPAPI or Aaron' RPG-XML would probably do

Hi
So it actually works pretty well, calling Java

from

RPG,
My requirement is to call a web service, from

AS400

application,
So i was trying to find, if i can call web

service

directly from RPGLE program, or call a java

program

from RPGLE which in turn would call the web

service.

Any hints or ideas about it
