  1. POQuartz scheduler running for two times in struts2
    text
    copied!<p>I have scheduled a JOB using Quartz scheduler in my Struts2 web application. Everything is working fine as I expected but the trigger is firing two times : on the specified time. After some research I found That <code>ApplicationContext</code> is loading twice. I found these links are useful. <a href="https://stackoverflow.com/questions/3289181/quartz-spring-crontrigger-fired-more-times-than-configured">Job Triggered twice</a> <a href="https://stackoverflow.com/questions/1464881/defaultannotationhandlermapping-via-contextloaderlistener-instead-of-dispatchers/1464886#1464886">Application Context loading Twice</a> But that was not so descriptive or I am unable to understand that. Please help to deal with this.</p> <p>Will provide the code on Request.</p> <p>My web.xml </p> <pre><code>&lt;?xml version="1.0" encoding="UTF-8"?&gt; &lt;web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0"&gt; &lt;display-name&gt;MyAPP&lt;/display-name&gt; &lt;welcome-file-list&gt; &lt;welcome-file&gt;index.html&lt;/welcome-file&gt; &lt;welcome-file&gt;index.htm&lt;/welcome-file&gt; &lt;welcome-file&gt;index.jsp&lt;/welcome-file&gt; &lt;welcome-file&gt;default.html&lt;/welcome-file&gt; &lt;welcome-file&gt;default.htm&lt;/welcome-file&gt; &lt;welcome-file&gt;default.jsp&lt;/welcome-file&gt; &lt;/welcome-file-list&gt; &lt;filter&gt; &lt;filter-name&gt;struts2&lt;/filter-name&gt; &lt;filter-class&gt;org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter&lt;/filter-class&gt; &lt;/filter&gt; &lt;filter-mapping&gt; &lt;filter-name&gt;struts2&lt;/filter-name&gt; &lt;url-pattern&gt;/*&lt;/url-pattern&gt; &lt;/filter-mapping&gt; &lt;listener&gt; &lt;listener-class&gt; org.apache.struts2.tiles.StrutsTilesListener &lt;/listener-class&gt; &lt;/listener&gt; &lt;context-param&gt; &lt;param-name&gt;tilesDefinitions&lt;/param-name&gt; &lt;param-value&gt;/WEB-INF/tiles.xml&lt;/param-value&gt; &lt;/context-param&gt; &lt;welcome-file-list&gt; &lt;welcome-file&gt;Login.jsp&lt;/welcome-file&gt; &lt;/welcome-file-list&gt; &lt;session-config&gt; &lt;session-timeout&gt;30&lt;/session-timeout&gt; &lt;/session-config&gt; &lt;error-page&gt; &lt;error-code&gt;404&lt;/error-code&gt; &lt;location&gt;/jsp/error/pagenotfound.jsp&lt;/location&gt; &lt;/error-page&gt; &lt;listener&gt; &lt;listener-class&gt; com.MYAPP.listners.QuartzListners &lt;/listener-class&gt; &lt;/listener&gt; &lt;/web-app&gt; </code></pre> <p>My QuartzListner.java</p> <pre><code>public class QuartzListner implements ServletContextListener { private static final Logger log=Logger.getLogger(QuartzListner.class); /* (non-Javadoc) * @see javax.servlet.ServletContextListener#contextDestroyed(javax.servlet.ServletContextEvent) */ @Override public void contextDestroyed(ServletContextEvent arg0) { // TODO Auto-generated method stub log.info("----Quartz Scheduler destroyer Intialized----"); try{ ServletContext context =arg0.getServletContext(); Scheduler scheduler =(Scheduler)context.getAttribute("DocRevScheduler"); scheduler.shutdown(true); log.info("----Scheduler Shutting downnn ---- "+scheduler.isShutdown()); }catch(Exception se) { log.warn("--Exception while Shutdowning the Scheduler..."+se); se.printStackTrace(); } } /* (non-Javadoc) * @see javax.servlet.ServletContextListener#contextInitialized(javax.servlet.ServletContextEvent) */ @Override public void contextInitialized(ServletContextEvent arg0) { // TODO Auto-generated method stub log.info("--Qurz Scheduler intialized----"); JobDetail job = JobBuilder.newJob(MailSendingJOB.class) .withIdentity("mailJob", "group1").build(); JobDetail jobDetail =JobBuilder.newJob(DBOperationsJOB.class) .withIdentity("DBJOB", "group2").build(); try { ResourceBundle resource = ResourceBundle.getBundle("resources.application"); Trigger trigger = TriggerBuilder .newTrigger() .withIdentity("anyTriggerName", "group1") .withSchedule( CronScheduleBuilder.cronSchedule(resource.getString("triggerTime"))) .build(); Trigger trigger1 = TriggerBuilder .newTrigger() .withIdentity("sampleTrigger", "group2") .withSchedule( CronScheduleBuilder.cronSchedule(resource.getString("triggetTime"))) .build(); Scheduler scheduler = new StdSchedulerFactory().getScheduler(); scheduler.start(); scheduler.scheduleJob(job, trigger); scheduler.scheduleJob(jobDetail, trigger1); ServletContext context = arg0.getServletContext(); context.setAttribute("MyJOBScheduler", scheduler); } catch (SchedulerException e) { e.printStackTrace(); } } </code></pre> <p>}</p> <p>In My Propertyfile <code>triggerTime=0 19 11 ? * MON *</code></p>
