Kirk What I recv'd back from Pgm'r.. >>> yep, the 8 char limit would be a huge limitation to building a class structure, but then again, we've been working with 4 char program names on SCORE for who knows how long... i'm sure we would come up with a nice convention for naming.
my desire is to execute everything solely within the TSO environment. so rather than writing my code and putting it in a jar file on HFS, and then in my batch job doing something like this: //XA344JVA JOB (6000),'AARON DUNLAP',CLASS=B,MSGCLASS=S, // MSGLEVEL=(1,1),NOTIFY=&SYSUID //********************************************************************* //SA20 EXEC PROC=JZOS, // JAVACLS='jabs.replication.upload.TASUploadMF', // ARGS='file:/u/eeepc/apps/config/mf/upload.properties' //STDENV DD * ... I want to do something like this: //XA344JVA JOB (6000),'AARON DUNLAP',CLASS=B,MSGCLASS=S, // MSGLEVEL=(1,1),NOTIFY=&SYSUID //********************************************************************* //SA20 EXEC PROC=JZOS, // JAVACLS='XA344.PDS.JAVA(TESTCODE)', // ARGS='A.P1.CM.ZZ.BRCH.PARMLIB(MYPARM)' //STDENV DD * ... within the context of the class structure of java, this might not make much sense though... From: Kirk Wolf <[email protected]> To: [email protected] Date: 08/03/2009 02:54 PM Subject: Re: Java question Sent by: IBM Mainframe Discussion List <[email protected]> FWIW, Java already has a mechanism for launching a Unix executable (binary, shell script, REXX script) as a child process, where stdin/stdout/stderr can be piped into the child process. It is not difficult to create a REXX shell script in the HFS filesystem that loads and executes MVS load modules. Calling MVS load modules directly from Java (in the same process) is another matter, and that is what I thought you were asking about earlier.
