 Scott,
I ran this command on IBM i 7.3:
    SBMJOB CMD('RUNJVA CLASS(garf.jar) PARM(barf)') +        JOBD(QGPL/QBATCHLOG) JOBQ(QGPL/QBATCH)  +        JOB(JAVABOMB)
where that class "garf.jar" does not exist ...  (on purpose).
The job ended "normally" but if I look at the job log, I see this:
Message . . . . :  -RUNJVA CLASS(garf.jar) PARM(barf)                             JVA0122    Escape                  00   02/22/22  13:33:36.354771  QJVAUTLJVM   QSYS        *STMT    QCMD        QSYS        01C8From module . . . . . . . . :   QJVAUTLJVM                                                  
> From procedure  . . . . . . :   JvaSendMsg                                                  Statement . . . . . . . . . :   10                                                          Message . . . . :   Java program completed with exit code 1                                 
Yet the job ended "normally."  
Seems something is very wrong here?
Perhaps a simple CL "wrapper" that can do a MONMSG for JVA0122 and then throw a CPF9898 *ESCAPE message, to cause the job to end abnormally?  
But why should that be necessary?
Hope that helps?

 Hi Doug,

I don't know why RUNJVA wouldn't work?  Check the CLASSPATH parameter 
of the RUNJVA command and see if someone changed it to something other 
than *ENVVAR?  Also, you might verify that none of the needed envvars 
(JAVA_HOME, CLASSPATH, etc) are being set only at the QShell level.

If they are set properly for the CL command line, it should work fine.
