How to instantiate and register a JobListener in the quartz.properties file? - quartz-scheduler

Question

I've read from many sources where people have said that it is possible and intended that a listener can be instantiated and registered to a scheduler all in the properties file
But I searched everywhere and can't find a single example of this.
Note: I am using this Quartz Initiazlizer Servlet to start my scheduler. Therefore I won't be able to use the conventional method of registering a JobListener to the scheduler. Other method of doing this is very accepted
Basically I want to do this:
JobListener jobListener = new SchedulerGlobalListener();
scheduler.getListenerManager().addJobListener(jobListener);
In this (under quartz.properties)
org.quartz.jobListener.NAME.class = com.foo.MyListenerClass
org.quartz.jobListener.NAME.propName = propValue
org.quartz.jobListener.NAME.prop2Name = prop2Value
*

Below is what I've tried and the results
#quartz.properties#
org.quartz.jobListener.SchedulerGlobalListener.class = com.scheduler.SchedulerGlobalListener
#listener class#
public class SchedulerGlobalListener implements JobListener {
private String name;
public SchedulerGlobalListener() {
}
public SchedulerGlobalListener(String name) {
if(name.isEmpty())
{
this.name = "SchedulerGlobalListener";
}
else
{
this.name = name;
}
}
#Override
public String getName() {
return name;
}
public String setName(String name) {
return name;
}
#Override
public void jobToBeExecuted(JobExecutionContext context) {
// do something with the event
}
#Override
public void jobWasExecuted(JobExecutionContext context, JobExecutionException jobException) {
System.out.println("I just ran this job: " + context.getJobDetail().getJobClass().getName());
}
#Override
public void jobExecutionVetoed(JobExecutionContext context) {
// do something with the event
}
}
Result:
INFO: QuartzInitializer: Quartz Scheduler failed to initialize: java.lang.IllegalArgumentException: JobListener name cannot be empty.

Answer 1

Thanks for the help guys. I totally missed this (under Quartz config documentation):
For example if the properties file contains the property 'org.quartz.jobStore.myProp = 10' then after the JobStore class has been instantiated, the method 'setMyProp()' will be called on it.
quartz.properties
org.quartz.jobListener.SchedulerGlobalListener.class =
com.scheduler.SchedulerGlobalListener
org.quartz.jobListener.SchedulerGlobalListener.globalListenerName =
SchedulerGlobalListener
SchedulerGlobalListener.java
public void setGlobalListenerName(String name) {
this.name = name;
}

You have already done things almost.
Please refer
this link.
You just have to specify the name of the listener class in quartz.properties file
and make sure that the specified listener class is in your classpath.
Refer this
article for how to use joblistener except the part to register the
joblistener with scheduler. Instead, add the above mentioned properties to quartz properties file.

Here you find how hor to use Quartz and wrtie and trigger your jobs
http://www.mkyong.com/java/quartz-joblistener-example/
In Quartz there is a cron expression which describes the interval of quartz job to start again here
http://quartz-scheduler.org/documentation/quartz-1.x/tutorials/crontrigger
http://docs.oracle.com/cd/E12058_01/doc/doc.1014/e12030/cron_expressions.htm
you found how to write cron expressions.
Quartz simple trigger
Trigger trigger = TriggerBuilder
.newTrigger()
.withIdentity("TriggerName", "group1")
.withSchedule(
SimpleScheduleBuilder.simpleSchedule()
.withIntervalInSeconds(5).repeatForever())
.build();
Quartz Cron Trigger
Trigger trigger = TriggerBuilder
.newTrigger()
.withIdentity("TriggerName", "group1")
.withSchedule(
CronScheduleBuilder.cronSchedule("0/5 * * * * ?"))
.build();
If you are using spring then all quartz properties you can mention in your context file as
<bean class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
<property name="triggers">
<list>
<ref bean="cronTrigger" />
<ref bean="simpleTrigger" />
</list>
</property>
<property name="quartzProperties">
<props>
<prop key="propertName">propertyValue</prop>
</props>
</property>
</bean>
and
<bean id="beanName" class="org.springframework.scheduling.quartz.SchedulerFactoryBean" destroy-method="destroy">
<property name="jobFactory">
<bean class="org.springframework.scheduling.quartz.SpringBeanJobFactory"/>
</property>
<property name="dataSource" ref="JNDIDataSource" />
<property name="transactionManager" ref="transactionManager" />
<property name="quartzProperties">
<util:properties location="classpath:/quartz.properties"/>
</property>
<property name="triggers">
<list>
<ref bean="triggerBean"/>
</list>
</property>
</bean>
