videlord,
Are you talking about BPXBATCH? If so BPXBATCH launches the Unix shell to run Java under a separate "OMVS" address space, the Java program doesn't have access to DD dataset allocations in the job step.
You need to pre-allocate the stdout and stderr datasets as shown here.
| Code: |
//BPXBATCH JOB '','USER',CLASS=A,MSGCLASS=X,MSGLEVEL=(1,1)
//********************************************************************
//* Cleanup existing HFS output files
//********************************************************************
//STEP1 EXEC PGM=IEFBR14
//STDOUT DD PATH='/tmp/&SYSUID..out',
// PATHOPTS=(OCREAT,OWRONLY),
// PATHMODE=SIRWXU,
// PATHDISP=(DELETE)
//STDERR DD PATH='/tmp/&SYSUID..err',
// PATHOPTS=(OCREAT,OWRONLY),
// PATHMODE=SIRWXU,
// PATHDISP=(DELETE)
//********************************************************************
//* Run Java under a Unix System Service shell
//********************************************************************
//STEP2 EXEC PGM=BPXBATCH,
// PARM='sh java HelloWord'
//STDIN DD DUMMY
//STDENV DD DUMMY
//STDOUT DD PATH='/tmp/&SYSUID..out',
// PATHOPTS=(OWRONLY,OCREAT,OTRUNC),
// PATHMODE=SIRWXU
//STDERR DD PATH='/tmp/&SYSUID..err',
// PATHOPTS=(OWRONLY,OCREAT,OTRUNC),
// PATHMODE=SIRWXU
//*********************************************************************
//* Copy HFS output files to SYSOUT
//*********************************************************************
//STEP3 EXEC PGM=IKJEFT01 ,DYNAMNBR=300,COND=EVEN
//SYSTSPRT DD SYSOUT=*
//HFSOUT DD PATH='/tmp/&SYSUID..out'
//HFSERR DD PATH='/tmp/&SYSUID..err'
//STDOUTL DD SYSOUT=*,DCB=(RECFM=VB,LRECL=133,BLKSIZE=137)
//STDERRL DD SYSOUT=*,DCB=(RECFM=VB,LRECL=133,BLKSIZE=137)
//SYSPRINT DD SYSOUT=*
//SYSTSIN DD *
OCOPY INDD(HFSOUT) OUTDD(STDOUTL)
OCOPY INDD(HFSERR) OUTDD(STDERRL)

If you want to pass more than 100 characters then you can use STDENV dd
| Code: |
//STDENV DD *
JAVA_HOME=/usr/lpp/java14/J1.4
PATH=$JAVA_HOME:$PATH
CLASSPATH=/u/myuid/:/u/myuid/lib/x.jar:/u/myuid/lib/y.jar:$CLASSPATH

Rather than executing Java as a shell command under Unix System Services, the JZOS batch launcher can be used to invoke the Java JVM directly from a batch job step address space:
| Code: |
//JZOSBAT JOB '','USER',CLASS=A,MSGCLASS=X,MSGLEVEL=(1,1)
//JAVAJVM EXEC PGM=JZOSVM14,
// PARM='com.foo.MyClass'
//STEPLIB DD DSN=JZOS.LIBRARY,DISP=SHR
//STDENV DD DUMMY < shell script to config env
//SYSPRINT DD SYSOUT=* < System stdout
//SYSOUT DD SYSOUT=* < System stderr
//STDOUT DD SYSOUT=* < Java System.out
//STDERR DD SYSOUT=* < Java System.err
|
Hope this helps...
Cheers
