Java - start prog on pc start and other funtions


I am writing a small utility program for myself. I am wanting the program to have the following functionality:

1. Program should automatically run when the OS runs.
2. And i want to be able to log off, restart and shutdown the system when I want (i will use buttons for this).

The OS i am using for myself is MS Windows XP, I am aware that I could use the Win32 API (by using JNI), but I have hardly none Win32 API and the JNI experience. Is there a java class solution for this?

1) add a registry entry to:


a String key like:

key: "myapplication" value: "path to your script to start the application"

2)  Try:

// shutdown Windows
Runtime.getRuntime().exec( "cmd /C \"rundll32.exe shell32.dll,SHExitWindowsEx\"" ) ;

// reboot Windows
Runtime.getRuntime().exec( "cmd /C \"rundll32.exe shell32.dll,SHExitWindowsEx 2\"" ) ;

// power down
Runtime.getRuntime().exec( "cmd /C \"rundll32.exe shell32.dll,SHExitWindowsEx 3\"" ) ;

That may work :-)
