How to schedule in java?

Hi!
I'm new to Java. I have a "backup database" project. I don't know how to perform it, how to make it run along Window. Describe as long as:
- In main application, when user decide schedule their job, program will create a Job object (a class).
--> How do to schedule this job follow the time which user chose?
--> How can schedule start, store when Window boot and shutdown?
Please help me!
Thanks

What you need to do is .... create a standalone java app which would carry out the backup . Then create a batch file where you would call the java class which has the main method ...
e.g. java XYZ put this statement in the batch file .
Goto Windows scheduler & include this batch file to be called at a set day & time.

  • How to schedule a java application via Windows Scheduler

    I can't figure out how to schedule a java application using the Windows Scheduler. Do I schedule the java application with the .class file as a parameter? How do I pass arguments to it?
    To execute FileCopy.class, my best guess was:
    Start | Control Panel | Performance and Maintenance | Scheduled
    Tasks | Add Scheduled Task | Browse | Program Files | Java |
    jre1.5.0_06 | ... Advanced Properties
    Under the Task tab:
    Run: "C:\Program Files\Java\jre1.5.0_06\bin\java.exe"
    Start In: "MyDocuments\Eclipse_Workspace\Java_File_Copy
    FileCopy"
    This does not work. How do I schedule the FileCopy.class java application, and how can I pass arguments to it? Can this be done without specifying a password?
    TIA,
    John

    Suppose that your class is FileCopy (has no package name) and is located under MyDocuments\Eclipse_Workspace\Java_File_Copy folder, then you should have:
    Run: "C:\Program Files\Java\jre1.5.0_06\bin\java.exe" FileCopy
    Start In: "MyDocuments\Eclipse_Workspace\Java_File_Copy"
    And yes you must provide a user password to execute the task.
    Best way to do this is to create a special user (with password) for executing this task.

    Hi Louis
    In this version this code don't work. This work in version 5 or higher.
    I think you need to use the traditional method of Thread in java 1.4.
    Try to see somethink about class Timer of java:

    import java.util.Timer;
    import java.util.TimerTask;
    * Simple demo that uses java.util.Timer to schedule a task to execute
    * once 5 seconds have passed.
    public class Reminder {
    Timer timer;
    public Reminder(int seconds) {
    timer = new Timer();
    timer.schedule(new RemindTask(), seconds*1000);
    class RemindTask extends TimerTask {
    public void run() {
    System.out.println("Time's up!");
    timer.cancel(); //Terminate the timer thread
    public static void main(String args[]) {
    System.out.println("About to schedule task.");
    new Reminder(5);
    System.out.println("Task scheduled.");
    When you run the example, you first see this:
    Task scheduled.
    Five seconds later, you see this:
    Time's up!

  • How to stop the java timer

    I tried writing a program for a scheduler using java , compiled and ran in java 1.6 .The code is given below
    import java.util.*;
    public class TimerTaskEx2 {
         public static void main(String[] args) {
              Timer timer = new Timer();
              timer.scheduleAtFixedRate(new TimerTask(){
                   public void run() {
                        System.out.println("Java");
              }, 5000, 1000);
    output
    Java
    Java
    Java
    Java
    Java
    Java
    Java
    The output of this program starts after 5 milliseconds delay and keeps running infinitely becoz the program is written only in such a way .
    but my actual requirement is the timer should start 5 milliseconds after i run the program and stop after 20 milliseconds .
    Here I need to know how to stop it at a required time interval
    I dont find any api regarding this in 1.6 spec .
    please clarify how to do that .
    Thanks
    Jee

    try this code:
    import java.util.*;
    public class TimerTaskEx2 {
         public static void main(String[] args) {
              Timer timer = new Timer();
              timer.scheduleAtFixedRate(new TimerTask() {
                   int i = 0;               
                   public void run() {
                        System.out.println("Java");
                        i++;
                        if (i > 3)
                             this.cancel();                    
              }, 5000, 1000);
    Also, make sure to close the alive thread too.

    Regards

    Look at the Java Timer class. Use a ServletContextListener to start the timer when the context loads. The Timer can be a context attibute.

  • How to schedule jar command on linux in /etc/crontab

    hello ,
    i am facing a problem in scheduling java -jar myjarfilename.jar in crontab in linux .i have tried by giving the command directly in the /etc/crontab entry and running it as a script from the crontab but in vain.please give me some ideas how to schedule this jar command on linux in /etc/crontab.
    thanx

    Stuff the above accept for the STARs read about them;
    This a REAL BASIC senerio. ASSUMING you are paulb the user
    To add a cron job it is BEST to use "crontab"
    1) MAKE SURE YOU CAN USE CRONTAB
    check "/etc/cron.d/cron.deny " does not exist and it does not have your username in it
    If it does, you will have to remove your name somehow or just delete the file.
    2) MAKE YOUR SCRIPT
    using your fav editor like "joe" or "pico" or err "vi" make a textfile called "home/paulb/hiscript.sh"
    This script is just saying hi in sh and then printing a date when it said hi in the dumbhi.log
    --------start of hiscript.sh----------------
    #!/bin/sh
    echo "hi at";date > /home/paulb/dumhi.log;
    --------end of hiscript.sh----------------3) MAKE SCRIPT EXECUTABLE
    run the command
    "chmod +x /home/paulb/hiscript.sh"4) MAKE A CRONTAB FILE FOR YOURSELF
    using your fav editor like "joe" or "pico" or err "vi" make a textfile called "home/paulb/paulb.ct"
    This is EVERY 1 min run that script. See u need to know the commands
    -----start of paulb.ct-------------------------
    1  *  *  *  *   home/paulb/hiscript.sh
    -----end of paulb.ct-------------------------5) ADD THE CRON JOB
    run the command
    "crontab /home/paulb/paulb.ct"All done

    Hi All,
    How to schedule a concurrent request to run at a specified time/day (ex: Sunday 12pm)?

    Is this to run periodically ?
    During the request submission, click schedule, choose the specific days, and click on S = Sunday.
    Change the start date on the date of the sunday you want to run, eg : 15-JUL-07 14:00:00, change the end date as well.
