Logoff computer using java

How to use java to log off windows. It could be using some windows own exe through Runtime(), or and other methods.It would be more efficient if you could provide some good alternative than using external programs like nircmd.exe .

When I use this code,

String shutdownCmd = "rundll32.exe shell32.dll,SHExitWindowsEx 0";
Process child = Runtime.getRuntime().exec(shutdownCmd);

I get

ERROR MSG

Do this (-l for logoff here, -r for restart, etc.):

String shutdownCmd = "shutdown -l";
Process child = Runtime.getRuntime().exec(shutdownCmd);

or (0 for logoff here): 

String shutdownCmd = "rundll32.exe shell32.dll,SHExitWindowsEx 0";
Process child = Runtime.getRuntime().exec(shutdownCmd);

You can also make a simple .bat file if it's just a file you want. Open notepad, type the code below, save as *all files, call it 'logoff.bat' or something and it should work.

shutdown -l

You could call the shutdown executable from the Runtime.getRuntime().exec(...) method. Check out this Q&A for details on that: How do I shutdown - restart - logoff Windows via a bat file?
