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

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.

Peace,

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