Cant use jrcmd on windows?

Question

I am on my Windows XP laptop and try to run jrcmd but it reports no pids. I am administrator of the machine.
1. start the java applet:
C:\bea\jrockit-R27.3.1-jdk1.5.0_11\demo\jfc\Notepad>java -jar Notepad.jar
2. run jrcmd in another cmd window:
C:\bea\jrockit-R27.3.1-jdk1.5.0_11\bin>jrcmd
C:\bea\jrockit-R27.3.1-jdk1.5.0_11\bin>

Hi Eric,
Thanks for taking the time to update the thread based on our offline discussion.
For anyone else, this is how jrcmd works:
===
1a) When JR is started on Windows, it creates a file named <PID> in %TEMP%\hsperfdata_USERNAME. This is typically “C:\documents and settings\USERNAME\Local Settings\hsperfdata_USERNAME”.
1b) When JR starts on Linux/Windows it instead creates a file name <PID> in /tmp/hsperfdata_USERNAME.
2) When jrmcd starts, it searches the temp\hsperfdata_USERNAME directory for entries and uses that list to locate running JRockit instances.
3) When a JRockit process stops, it removes its entry. If it crashes, it will instead be cleaned up by the next JRockit started on the same machine by the same user.
I hope that helps your troubleshooting. Maybe %TEMP% has been undefined or there isn’t enough disk space on your Windows machine.

In Eric's case the problem might have been incorrect rights configured on the hsperfdata_USERNAME directory. Maybe something caused by a Unix-on-Windows tool like cygwin?
