How to kill javaw.exe

December 2011.

The situation

You have some java processes running on your system but you can't stop or kill them. You tried using the task manager and sysinternals' process explorer.

The solution

Find the PID of your java process

C:\>jps -l -v
3100 -Dapplication.home=C:\Program Files\Java\jdk1.6.0_24 -Xms 8m
2904 C:\Program -Xms40m -Xmx256m -XX:MaxPermSize=96m -DXPCOM.RUNTIME=C:\Program
Files\Texas Instruments\ccsv4\DebugServer\win32 -Dxpcom.bridge.executeOnDedicate
dThread=yes -Dorg.eclipse.swt.browser.XULRunnerPath=C:\Program Files\Texas Instrument\ccsv4\DebugServer\win32 -Dosgi.instance.area.default=file:/C:/Documents and Settings/SomeUser/Mes documents/workspace/

Here we want to kill the nasty eclipse process 2904.

Use taskkill.

C:\>taskkill /F /PID 2904
Opération réussie : le processus avec PID 2904 a été terminé.

If you don't use option /F, the command will still execute successfully but nothing will happen.
