Re: Call Java program from RPGLE -- JAVA400-L

Scott's HTTPAPI or Aaron' RPG-XML would probably do what you want.

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
