quartz-scheduler

I'm looking into using Quartz Scheduler, and I was wondering if it was possible to schedule jobs not by time, but when another job finishes. So, when Job A is done, it starts Job B. When that's done, it starts Job C, etc. Job A -> Job B -> Job C -> Job A... continuously. Is this the right tool for the job? Or should I be looking into something else? Check out JobChainingJobListener , built-in to Quartz (bold mine): Keeps a collection of mappings of which Job to trigger after the completion of a given job. If this listener is notified of a job completing that has a mapping, then it will then

I used the below way to run the schedule on every two weeks on mondays. ITrigger trigger = TriggerBuilder.Create() .StartAt(DateBuilder.DateOf(StartHour, StartMinute, StartSeconds, StartDate, StartMonth, StartYear)) .WithCalendarIntervalSchedule(x => x.WithIntervalInWeeks(Int32.Parse(nWeekInterval))) .EndAt(DateBuilder.DateOf(0, 0, 0, EndDay, EndMonth, EndYear)) .Build(); But how can I use a single schedule to run on mondays and tuesdays as well. Please advice. You can specify days of the week with DailyTimeIntervalScheduleBuilder var onMondayAndTuesday = DailyTimeIntervalScheduleBuilder

I have a web application that was developed using Grails. I'm trying to implement a background process that scans a table in DB for every 5 mins using quartz1.0-RC9 plugin for Grails. Before trying to code the actual logic I'm learning how to use the plugin as I'm new to quartz. So I created a job that prints the message "hai" with the current timestamp for every 5 seconds. class checkJob { static triggers = { simple name:'sampleQuartz', startDelay:10000, repeatInterval: 5000l, repeatCount: -1 // execute job once in 5 seconds } def execute() { println "hai!!!"+new Date()// execute job } } And

Please find updated code that repeats every 10 seconds. However the issue is that it creates a new GUI on the screen every 10 seconds rather than ONLY updating the data every 10 seconds. please can you advise package learningfromscrach; import java.awt.*; import java.awt.event.ActionEvent; import java.awt.event.ActionListener; import java.io.IOException; import java.util.logging.Level; import java.util.logging.Logger; import javax.swing.*; import javax.swing.border.TitledBorder; import org.jsoup.Jsoup; import org.jsoup.nodes.Document; import org.jsoup.select.Elements; import javax.swing

I have configured quartz in my application. It works on cluster and i can see cluster nodes are triggering jobs one at a time. However, i have a question about how load balancing algorithm works in quartz. I want to know at what point in jdbcJobstore code, a node get information that it can not acquire a lock.How a particular cluster node acquire a lock to trigger a job in code? Quartz uses no explicit load-balancing. What happens is that individual clustered Quartz scheduler instances compete to execute jobs. When the time comes and a job should be executed, individual scheduler instances

I have one spring batch job which will run daily once. I had implemented reader, processor and writer. Suppose if any exception happens while running reader task, then entire job will fail. I want to rerun same day for that failure jobs after 5 mins or immediately. Kindly let me know how i can implement in spring batch or provide me any sample code or website which have information. Take a look at Spring Retry . It started as part of Spring Batch but as of version 2.2.0 it has spined-off to a standalone project (and dependency). Being able to use it declaratively is particularly nice: import

I want to use quartz in my small and simple web application. (Quartz 2.1.6 and tomcat 7.0.22). I want to change trigger cron expression without restart my application. I put jobs in xml file quartz-jobs.xml and set up XMLSchedulingDataProcessorPlugin in quartz.properties Problem: when i change content of quartz-jobs.xml , quartz deceted file was changed and reload it, delete and create new job. I see it in log file. But content of this file is old (the same as it will on startup). So i have in filesystem new version of quartz-jobs.xml , but quartz takes somewhere old version of that file.
