    Default java program hangs when executed

    Hi everyone. I m having trouble in a java program. i am trying to execute bash script through a java GUI program in linux. current coding which i am using can actually perform the job but it hangs whenever i press the button. I have to terminate the program through NetBeans IDE stop process. What should I do?

    This is the code which i am using..

    try {
    Process proc = Runtime.getRuntime().exec("/home/user/Desktop/sources_files/script2.sh /");
    BufferedReader read = new BufferedReader(new InputStreamReader(
    proc.getInputStream()));
    try {
    proc.waitFor();
    } catch (InterruptedException e) {
    System.out.println(e.getMessage());
    }
    while (read.ready()) {
    System.out.println(read.readLine());
    }
    } catch (IOException e) {
    System.out.println(e.getMessage());
    }

    That's not really a question we can reply to. What did you try, specifically? What specifically were you confused about? Where is your updated SSCCE?
