Sun's documentation states that JPS may not be supported in future versions
of JDK.. also, it is not supported in Windows 98 and Windows ME... So I
guess JPS will not be a good choice after all...
with no other generic support to retrieve process ids and take some action
based on the status, it seems to be restricted to using 3rd party tools...

RE: AW: how to get a process id from a spawned task?
Posted by Ka...@thomson.com.
This snippet doesn't exactly give you the PID, but it gives something
that's close enough for what I needed (and may be sufficient for the
OP's use case, I'm not sure):
import java.lang.management.ManagementFactory;
...
ManagementFactory.getRuntimeMXBean().getName(); // gets PID of
current process
What this gives you is a string something like "2444@localhost"; we've
used it on Windows and on Linux. If all you want is the PID part, it's
simple enough to parse it out.
As far as killing a process (in Windows), XP's Task Manager can display
PIDs as an additional column in the Processes tab...

well, the fact that even in java5 there's nothing in the Java APIs to
give you the process ID of a started process is going to make it hard.
If someone knew how JPS worked (i.e. there was an official Java

I was hoping not to use any 3rd party tool but maybe something via ANT tasks
or Java calls. One of the similar threads mentioned about 'jps' but could
not get it working. Keeping it generic so that it can be used not only for
windows will be a good approach.

if you're runnning on windows maybe you can go via <exec> combined with
PSKILL which is part of the PTOOLS suite, formerly Sysinternals now
under the hood of Mystersoft =

never tried it myself, give it a shot.

I was thinking more of listing the current running processes in windows and
then killing one of them.

I followed the suggestion that Prashant had provided and executed jps from
within ant by using <exec>. However, if I want to kill a process running
under windows, how will I be able to do that ?
