Starting a process with inherited stdin/stdout/stderr in Java 6

Question

If I start a process via Java\'s ProcessBuilder class, I have full access to that process\'s standard in, standard out, and standard error streams as Java InputStreams

Answer 1

For System.in use the following pipein() instead of pipe()

pipein(System.in, p.getOutputStream());

Implementation:

private static void pipein(final InputStream src, final OutputStream dest) {

    new Thread(new Runnable() {
        public void run() {
            try {
               int ret = -1;
               while ((ret = System.in.read()) != -1) {
                  dest.write(ret);
                  dest.flush();
               }
            } catch (IOException e) { // just exit
            }
        }
    }).start();

}
