running shell commands from within code

Hi all,

I need someone with a bit more experience of java than me to give me a
few pointers on this one..

I've got a program called spistartup.tini. What I need to do is have a
line in this program which executes a command on the slush command line
to run another program. The command to run is...

>java spiout.tini 27

... where spiout.tini is the program and 27 is the runtime argument.

I've seen a method called 'execute()' in com.dalsemi.system.TINIOS but
as a kind of java virgin, the following doesn't really make sense to
me...

execute
public static void execute(java.lang.Object[] commandLine,
                           SystemInputStream in,
                           SystemPrintStream out,
                           SystemPrintStream err,
                           java.util.Hashtable env)
                    throws java.lang.ExceptionExecutes a command in the
shell.
Parameters:
commandLine - An Object array containing the command in the first
element, followed by any parameters need for that command in a String[]
in the second element.
in - The stream the command will use to get input.
out - The stream used to report non-critical messages.
err - The stream used to report critical messages.
env - A table of environment variables.
Throws:
java.lang.Exception - Any exception raised by the command.


How do I actually write this into my spistartup.tini program???

Any help would be appreciated.
