        BufferedReader stdInput = new BufferedReader(new 
                InputStreamReader(p.getInputStream()));

        BufferedReader stdError = new BufferedReader(new 
                InputStreamReader(p.getErrorStream()));

        // read the output from the command
        String s="";
        
        while ((s = stdInput.readLine()) != null) {
            System.out.println("Std OUT: "+s);
        }
        
        while ((s = stdError.readLine()) != null) {
            System.out.println("Std ERROR : "+s);
        }
