Re: Call java program on Windows from RPGLE or CL

[Scott Klement <rpg400-l@xxxxxxxxxxxxxxxx>]

Hi Ash,

Why not set up the Java program on the PC as a web service?  That seems 
to be the modern approach to this type of application.

If it really must be invoked as a normal program, you could use the 
RUNRMTCMD command or the rexec() API.  These two tools speak the same 
network protocol, but the API lets you get the information straight back 
into your RPG program, whereas the CMD sends it's output to the spool -- 
so you have to copy it back to a PF and read it into your RPG program. 
RUNRMTCMD/rexec is plaintext and unencrypted, though.

The SSH program from OpenSSH (available in PASE via 5733-SC1) allows a 
remote command to be run on another system via a protected/encrypted 
connection.  However, I don't know how to run an SSH daemon on Windows 
(it's probably possible, but is something I've never looked into, since 
we don't use Windows in that capacity here.)  I've used it against a 
FreeBSD server and it works very nicely as well.

Good luck
