Hi again Doug,
There is a pretty neat utility to easily display the contents of STDOUT. It is part an IBM document,
https://www.ibm.com/support/pages/example-rpgle-program-calling-helloworld-java-program. Here are the relevant parts:
If you call the RPG program in an interactive job, you have to do some extra work to show the Java output, which is sent to the "standard output". Compile the RPG code in DSPSTDOUT.RPGLE at the end of this document and call that program to show everything that was sent to standard output in your job. It will show the most recent output first, and you can scroll up to see earlier output.
DSPSTDOUT.RPGLE: ILE RPG code to display the standard output. Create this program using CRTBNDRPG.
CTL-OPT ACTGRP(*NEW);
DCL-PR printf EXTPROC(*DCLCASE);
p POINTER VALUE OPTIONS(*STRING : *NOPASS);
END-PR;
DCL-PR getchar INT(10) EXTPROC(*DCLCASE) END-PR;
DCL-C EOL x'15';
printf (EOL);
getchar ();
return;
It works! In the session you have run the Java program in you can view the contents of STDOUT with CALL DSPSTDOUT.

Subject: RE: RUNJVA question
Hello Doug,
Have you tried overriding the STDOUT and STDERR into spool files?
OVRPRTF FILE(STDOUT) TOFILE(QSYSPRT) HOLD(*YES) OVRPRTF FILE(STDERR) TOFILE(QSYSPRT) HOLD(*YES)
I hope that helps.

Subject: RUNJVA question
I have a java program with several System.out.print(); commmands in it.
When I run the program interactively on a 5250 session using only the RUNJVA command, I see the various messages on the screen, as I expect, in the terminal window.
If, however, I run the same RUNJVA command within a CL and Call that CL in a 5250 session, I do not see the System.out.print() messages when the RUNJVA command executes. Why? What is suppressing these messages?
In addition, if I submit that CL to batch, I also do not see the messages.
I have tried the CL with OUTPUT(*PRINT) and/or OPTIONS(*VERBOSE), and still, there is no logging of the messages in either the job log, nor a spool file entry [which I was expecting with OUTPUT(*PRINT).
I have posed this question to IBM in a case on 10/3 and they are still working on it.
We are not at the bleeding edge of PTFs but fairly current and on V7R4.
Has anyone else experienced this or know why the system behaves like this?
Thank you,
Doug
