Is it possible to shutdown a user's computer from within Java?

YES !

You only need to localize the SO command to shutdown your computer and
execute it from java !!.

if you are trying to shutdown the computer from an applet this needs
to be signed

On which of the many platforms that Java supports? Linux? Unix? Mac?
Windows? Java is a platform-independent language -- you write your code once
and it runs on every platform. Shutting down the OS/computer is a platform-
dependent operation -- it is done differently on each platform. To
accomplish this, you would need to determine the operating system using Java
system properties and call C/C++ code via JNI to actually do the system
shutdown.

Cheers!

Well...

im not an orthodox or a conservative about Java, speaking loud about
his platform independency.

You can doit in java and it counts !!

The Power of java is about posibilities, not about the fool
conservative myths.

First off, I left that signature in there to emphasize an irony.

Second, I disagree with your reasoning. The point of Java was to try to
create a platform-independent model. This isn't about conservatism, it's
about trying to save others headaches when they try to run your program
from less common system.

Finally, you *cannot* do it in Java per se. The closest one can get is
to hack in a Runtime.exec call or use JNI; JNI requires use of another
language, and a Runtime.exec call at best assumes the presence of other
functions.

Please demonstrate (with real Java code) how one would shut down an IBM
system running AIX, using only java.

Cheers!

I was thinking something cross platform. Maybe something in the API?
