Re: RPG/Java interaction

Doug,

I'm assuming (since I'm not familiar with your applications) that the reason you'd get "end code 0" is that the program isn't reporting an error.

Does that mean that the Java program isn't throwing an error message back to it's caller?

Or does that mean that is sending a message, but RUNJVA is ignoring it and proceeding as if nothing went wrong?

If the Java program isn't throwing an error, it doesn't matter what you do in the RPG program -- the problem is on the Java side.   But if it is throwing the error, and RUNJVA is ignoring it, then you could, indeed, write an RPG program to solve it.

We are on V7R3 with very recent CUMEs.

We have a Java program that runs under WRKJOBSCDE using the RUNJVA
command. It basically reads a DB2 table containing a list of files and
sends those files to a remote server.

There are times when the remote server is down, and the job produces a
printout, but has a Job Ending code of zero, even though the job wasn't
really complete. There is a small printout within the job that can show it
failed, but the system views the run as successful.

I was thinking of writing a small RPG wrapper that will run the Java
program in hopes I can call the Java with something like a CALLP(e)
javapgm();
and monitor the success of the Java program that way [using %error]. But,
I am not sure if that will work since Java is not seeming to really report
an error.

Does anyone have any ideas on how I would accomplish this? Ideally, if the
Java program fails, I would like the system to try again after waiting 10
minutes.

I don't want to reinvent the world here, but would like to know if anyone
else has done something like this successfully.

Thank you,

Doug
