I think that's right.  So for an interactive job, you might:
1) Sign on
2) 0800 Run JavaMail - JVM starts
3) 0820 Run payroll all day - JVM still running
4) 1730 Run alphaWorks BattleBot - uses same JVM that started at 0800

And if you need a different CLASSPATH at 1730 than you did at 0800, you're
stuck.  It's time to sign off (end the JVM), sign on and start BattleBot
(which starts a new JVM, picking up the new, different CLASSPATH).

One way to avoid all these gyrations is to submit each Java program to
batch, where it runs using it's own CLASSPATH.  I am not nearly as sure what
happens if you use QSHELL.  Joe might have some insight there.
