Most people solve this by using a data queue fed server job that actually runs the Java code. that way you can shut down and restart specific instances without having t kill the jobs using them.

I think the OPs problem is that the NEP has been running in batch for a
month, working great, and now he has to deploy updates - a new .jar file.

How does one tell the batch job to get the new .jar file?

Is it possible to restart a JVM for a job or Reload Jar files/classes

updated jar files and changing the class path while job is still active.
Current solution is to end the job and start a new job.

That's how I do it. If you use data queues to communicate with the Java
app, add a special message that will submit a new job and terminate this
one. You can make sending this 'restart' message part of the script
that deploys the new code into production.
