First, before doing anything else, get JZOS. It is fantastic and makes running Java in Batch almost simple. It comes bundled with the current IBM Java 1.5, 64-bit SDK. If you don't have that, then go to: http://www-03.ibm.com/servers/eserver/zseries/software/java/jzos/overvie w.html Now, to compile Java, you must have the .java files in a UNIX file. It cannot be in a sequential file, or member of a PDS, or anything like that (at least as best as I can figure out). Of course, you could keep it in a PDS and OCOPY it to an intermediate UNIX file in order to compile. But the resultant .class file must remain in a UNIX file. You cannot execute Java from a z/OS legacy dataset of any type (if somebody has done this, I would love to know how!). JCL for a compile: // SET CMD1='SH . /etc/profile; . ~/.profile; javac helloWorld.java' //PS001 EXEC PGM=BPXBATCH,REGION=6M, // PARM='&CMD1 ' //STDOUT DD PATH='/tmp/TSH009.stdout', // FILEDATA=TEXT, // PATHOPTS=(OCREAT,OAPPEND,OWRONLY,OEXCL),PATHMODE=SIRWXU //STDERR DD PATH='/tmp/TSH009.stderr', // FILEDATA=TEXT, // PATHOPTS=(OCREAT,OAPPEND,OWRONLY,OEXCL),PATHMODE=SIRWXU //STDIN DD PATH='/dev/null', // PATHOPTS=(ORDONLY) //* //PRINT EXEC PGM=IKJEFT01 //SYSTSPRT DD SYSOUT=* //HFSERR DD PATH='/tmp/TSH009.stdout',PATHDISP=(DELETE,DELETE) //HFSOUT DD PATH='/tmp/TSH009.stdout',PATHDISP=(DELETE,DELETE) //STDERR DD SYSOUT=*,DCB=(RECFM=VB,LRECL=4096) //STDOUT DD SYSOUT=*,DCB=(RECFM=VB,LRECL=4096) //SYSPRINT DD SYSOUT=* //SYSTSIN DD * OCOPY INDD(HFSERR) OUTDD(STDERR) OCOPY INDD(HFSOUT) OUTDD(STDOUT) Change the PATH= on the STDOUT and STDERR as you need to. I used those names simply as an example. BPXBATCH on z/OS 1.6 cannot write directly to JES SYSOUT, unfortunately. The OEXCL will cause a JCL error if the files exist. You can remove it if you want to overwrite the files, if they exist and you have the authority to overwrite them. -- John McKown Senior Systems Programmer HealthMarkets Keeping the Promise of Affordable Coverage Administrative Services Group Information Technology The information contained in this e-mail message may be privileged and/or confidential.
