JZOS is great but here's a IVP job using OSHELL I run to exercise the
HelloWorld program supplied in the java bin directory.
To write your own no doubt there's a source example out there that you can
compile (javac) and run.
//TSO EXEC PGM=IKJEFT1B,DYNAMNBR=50,REGION=0M
//SYSPROC DD DISP=SHR,DSN=SYS1.SBPXEXEC
//STDENV DD *
JAVADIR=/usr/lpp/java/J7.0
//SYSTSIN DD *
oshell +
PATH=$JAVADIR/bin:$PATH && +
echo path=$PATH && +
java -version
oshell +
PATH=$JAVADIR/bin:$PATH && +
java -classpath $JAVADIR HelloWorld
//SYSTSPRT DD SYSOUT=*
//SYSOUT DD SYSOUT=*
//SYSPRINT DD SYSOUT=*
//SYSIN DD DUMMY
//
Output:
path=/usr/lpp/java/J7.0/bin:/bin:/usr/lpp/java/J5.0_64/bin:.
