I am writing some java code that creates a file on my zOS system via some java code running on the mainframe. After this file is created I want to be able to submit it as batch.
I have tried using the tso sub command with both the -o and -t flags in use, but have been told that since tso sub is an APF authorized command I cannot use it directly from Java. It was then recommended that I use a REXX script to get the job done, but I am trying to develop this program solely on Java. I am sure there must be a back-door way to submit a batch job via Java.
The following is a Java package to allow JCL submission

ddname=ZFile.allocDummyDDName();
ZFile.bpxwdyn("free fi("+ddname+")");
ZFile.bpxwdyn("alloc fi("+ddname+") sysout(x) writer(INTRDR) recfm(f) lrecl(80) msg(2) reuse");
intrdr=FileFactory.newBufferedWriter("//DD:"+ddname);
}
public void write(String statement)
throws java.io.IOException
{

cardCount++;

[/code]
BTW - the latest version of JZOS on alphaWorks (2.1.1) has sample code for submitting JCL and getting job status via a REXX child process. This has the advantage of returning the jobname and jobid of the submitted job.
Just curious?
Is it possible, alone with obtaining the Job Id, to get the start and ending times of a particular Jobname, with the above REXX child process?
