Run tool.. and stop on mouse and keyboard movements!!

Question

Hello frnds,
I would like to share a problem with all of you..!!.. and need some advice!!
I have a tool "optimizer" which takes a hell lot of time in optimizing images.. I have to pass some arguments to it.. (the optimizer script.. and output path).. so am writing arguments in separate file.. "sample.txt"
I am doing it by reading contents of sample.txt and passing to optimizer.. 1 by 1
String cmd = new String[3];
cmd[0] = "optimizer.exe";
cmd[1] = "Optimizer_script.txt";     //coming from sample.txt
cmd[2] = "temp/folder";               //same
try { Process process = Runtime.getRuntime().exec(cmd); }
catch (IOException ex) {}Thts ok.. running fine..
Now what i want.. once process started if user.. presses keyboard or mouse..
the program
1. shows an message "Optimizer is running.."
2. does not allow user to do anything!!
and then stop(System.exit(0);Message = "Optimzer stopped") before reading next arguments from sample.txt.. (optimizer dont read next line in sample.txt).. and again when optimizer started it runs from same line.. I can do it by marking that line..!!
well frnds please tell me how to track mouse and keyboard actions.. whats the best way to do.. wht am trying to achieve!!.. Do I have to take care of how much time "optimizer.exe" takes.. in executing first line??.. if yes.. how to do that?
Thanking in advance
