    Default Ajax in servlet to change value of variable.

    Good day guys!

    I have a servlet that creates a web interface thorught ajax. Something like this...

    public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException,
    IOException {
    PrintWriter ajax = new PrintWriter(response.getOutputStream());
    String action = request.getParameter("action");

    if ("start".equals(action)) {
    if (sched != null) {
    try {
    JobDetail jd =
    new JobDetail(JOB_NAME, GROUP_NAME, MMPreProcessorSchedulerJob.class);
    CronTrigger cronTrigger =
    new CronTrigger(TRIGGER_NAME, GROUP_NAME);
    String cronExpr = "0 0, 3, 6 * * ?";
    ajax.println(" <head>");
    ajax.println(" <title>MMPreProcessorScheduler - Web Interface</title>");
    ajax.println(" <link rel=\"stylesheet\" type=\"text/css\" href=\"css/mystyle.css\"></link>");
    ajax.println(" </head>");

    What I want is for my web interface to accept an input through a text field and and store that value on CronExpr variable which will be used by my servlet. How is this possible? I'm still a beginner with java.

    Thank You IA :)

    You can get the value from the input field, and pass it as a parameter.
    Is that what you are trying to do?

    I am not sure whether your servlet is working without any issues. If it's working fine, you could use request.getParameter() to get the input value.
