Andy,
I tried your command (with extra debugging) on Struts 1.2.4, Tomcat 5.0.28,
Windows XP Home Edition. Debugging returned the same error code 0 but I
detected the following messages which clearly explained the problem on my
configuration:
> The operation completed successfully.
> A required privilege is not held by the client.
> Command "cmd.exe /C shutdown -r -f -t 60", exit code: 0
So, this begs the question, what user (and permissions level) does your web
application or web service run under on Windows XP? Does it run as a
service while you debug under you, an admin-level user? I run Eclipse and
Tomcat under myself, a non-privileged user. It reduces the possibility of a
web-based or e-mail based virus from getting into my system. I just login
as "admin" when I need to install anything (not very often).
Here is my Action's relevant java code:
=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
String cmd = "cmd.exe /C shutdown -r -f -t 60";
Runtime runtime = Runtime.getRuntime();
Process p = runtime.exec(cmd);
InputStream is = p.getInputStream();
int it = 0;
while ( (it=is.read())> 0 ) {
System.out.print( (char)it);
}
System.out.println("Command \"" + cmd +
"\", exit code: " + p.exitValue());
p.destroy();
=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
Regards,
David

It looks like you are getting the return code from cmd, rather than
shutdown. Could it be that the process you spawn doesn't have it's
environment correctly set up - maybe it can't see shutdown?
I'd try 1) changing my call to exec to call shutdown, with a full path,
directly rather than getting cmd to do it. 2) Call a batch file instead -
have the batchfile echo the environment to a file 3)Try and get the Java
process to create an interactive cmd for you (maybe cmd /k) - that way you
can try various commands in the same context that the Java process can.
