It's fairly easy to execute a command that's in your PATH, for example, ls

Code:
import java.io.InputStream;
import java.io.IOException;

public class foo
{
   public foo()
   {
       Runtime rt = Runtime.getRuntime();
       Process p = null;
       try
       {
           p = rt.exec( "ls -l" );
       }
       catch ( IOException ioe )
       {
           System.out.println( "Error executing file" );
       }
       InputStream output = p.getInputStream();
       System.out.println( output );
   }

   public static void main( String args[] )
   {
       foo f = new foo();
       System.exit( 0 );
   }
}

Scripts are a little more work, have a look here

that should help.

EDIT: My code worked for commands, not scripts. Hay ho.

airport2-ipinspector

AIRPORT2-IPINSPECTOR(1) 				      General Commands Manual					   AIRPORT2-IPINSPECTOR(1)

NAME

       airport2-ipinspector - WAN monitoring utility for the Apple AirPort Extreme Base Station ("Snow")

SYNOPSIS

       airport2-ipinspector

DESCRIPTION

       airport2-ipinspector  monitors the WAN interface of the base station and sends an email notification whenever the external (WAN) IP address
       of the base station changes.

OPTIONS

       airport2-ipinspector accepts no command-line options. airport2-ipinspector is a wrapper script around the IPInspector.jar jar file  located
       in /usr/share/java/airport-utils.

       You  can set the JAVACMD environment variable to use a specific JVM instead of the one chosen by the wrapper script. Set the DEBUG environ-
       ment variable to 1 to get the debug output from the wrapper script.

ENVIRONMENT VARIABLES

       DEBUG  Set this variable to 1 to get the debug output from the wrapper script.

       JAVACMD
	      The full path to the Java Virtual Machine to use.  By  default,  the  wrapper  uses  JAVACMD;  if  it  is  not  set,  it	looks  for
	      JAVA_BINDIR/java, then for JAVA_HOME/bin/java before looking for a java executable in the PATH. In the latter case, the JVM used can
	      be configured using the Debian alternatives system (see update-alternatives(8)).

       JAVA_HOME
	      The full path where your JDK/JRE is installed.

       JAVA_BINDIR
	      The full path to the directory where the java executable is located.

       JAVA_ARGS
	      Extra command-line arguments to be passed to the Java Virtual Machine.
