I am learning quartz and Have tried some samples which works in Console application. Now am trying in web aplications. Following is what I did.
web.xml
<?xml version="1.0" encoding="UTF-8"?>
<web-app>
<servlet>
<servlet-name>QuartzInitializer</servlet-name>
<display-name> Quartz Initializer Servlet</display-name>
<servlet-class>org.quartz.ee.servlet.QuartzInitializerServlet</servlet-class>
<load-on-startup>1</load-on-startup>
<init-param>
<param-name>config-file</param-name>
<param-value>quartz.properties</param-value>
</init-param>
<init-param>
<param-name>shutdown-on-unload</param-name>
<param-value>true</param-value>
</init-param>
<init-param>
<param-name>start-scheduler-on-load</param-name>
<param-value>true</param-value>
</init-param>
</servlet>
</web-app>
quartz.properties
org.quartz.plugin.jobInitializer.class = org.quartz.plugins.xml.XMLSchedulingDataProcessorPlugin
org.quartz.plugin.jobInitializer.fileNames = quartz-config.xml
org.quartz.plugin.jobInitializer.failOnFileNotFound = true
org.quartz.plugin.jobInitializer.scanInterval = 10
org.quartz.plugin.jobInitializer.wrapInUserTransaction = false
# Configuring ThreadPool
org.quartz.threadPool.class = org.quartz.simpl.SimpleThreadPool
org.quartz.threadPool.threadCount = 30
org.quartz.threadPool.threadPriority = 5
quartz-config.xml
<?xml version="1.0" encoding="UTF-8"?>

KpubScheduler.java
import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;
import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;
import org.quartz.StatefulJob;
public class KpubScheduler implements StatefulJob {
protected static final Log log = LogFactory.getLog(KpubScheduler.class);
public void execute(JobExecutionContext context) throws JobExecutionException {
try {
System.out.println("Quartz Config..........");
log.info("entering the quartz config");
} catch (Exception ex) {
log.info("entering the quartz config");
}
}
}
Now I have started the server. After it gets started, my KpubScheduler has to get invoked and I should get the log info's and Sysout's. But Nothing is happening. If I have a look at the log, its just giving this
Dec 29, 2010 8:21:37 PM org.apache.catalina.core.ApplicationContext log
INFO: QuartzInitializer: Scheduler has been started...
Dec 29, 2010 8:21:37 PM org.apache.catalina.core.ApplicationContext log
INFO: QuartzInitializer: Storing the Quartz Scheduler Factory in the servlet context at key: org.quartz.impl.StdSchedulerFactory.KEY
What may be the problem?. Am I doing it right?.
