moving on to your question: not sure exactly what you want to monitor but if you want to see if the java process is active, then you can trace the system calls with 'truss' or 'trace' (depending what system your on).
grab the pid and do: truss -p $pid
This is truss at a very basic level, so have a look at the man page if you need to delve in any further and of course, you'll need to be root to run truss.
if a process is inactive then you'll get output similar to this:
# truss -p 2018
connect(6, 0x0002CBEC, 16) (sleeping...)
if it busy, then get ready to watch the output scroll faster than you can read it. If this is the case then you can re-direct the output to file and examine at your leisure.
hope this helps?
