Two quick questions

[JS]

Hi all, just two quickies
Firstly, is there any way of making a Java method to shutdown a computer? I
need to be able to shitdown the server from a remote location, I can do the
sockets and all that bit but the only way I can think of at the moment is
moving the mouse around and shutting it down like that, which could take a
while to code.
Secondly, This may sound really simple but which Audio class from the Java
1.4.2 API should be used to open, play, stop and pause audio files
preferably *.mp3 and *.wma. I keep looking through the API but cant find a
single class which seems to deal with this.
Thanks in advance on either/both points

what server ? running what ?
JNI, Corba etc should do it.

This is platform specific. You exec an external program or whatever
your platform calls a bat file to do it. See

Hi,
I will answer the first question, since the shutdown function is not a
part of the standard Java AFAIK:
1. You have to write a DLL that uses a function like ExitWindowEx.
2. Use the JNI to access and use this DLL.

No.

Since that's (very!) platform-dependent, probably the easiest thing to do is
find the appropriate external command (for your combination of local and remote
OSes -- which of course may be different), and then execute that program from
Java.

Sorry, I forgot about details of the system. its a simple win98SE
installation that i want to shutdown. I can call the method easily enough
over the network but its what the method does that im stuck on.
Thanks for your help so far everyone, any more suggestions welcome
