Wait for some suggestion~~~I hope that as well as waiting for the solution, you are researching for yourself?
Obviously, you can't monitor the process directly (it's another process), but you can see its output. If the exe provides progress output you can capture that, parse it, and use it to update a JProgressBar. For example (without exception handling or boilerplate code):
//Set the process running
String cmd = "myexec --verbose";
Process p = Runtime.getRuntime().exec(cmd);
//Capture the output
BufferedReader in = new BufferedReader(new InputStreamReader(p.getInputStream()));
//Read the output and extract any progress info
String line = "";
while ((line = in.readLine()) != null) {
    int progress = myParseProgress(line);
    updateProgress(progress);
// and so on.../k1
