How to make sure quartz.properties is being used?

Question

I set following properties in my quartz.properties file:

org.quartz.threadPool.threadCount = 60
org.quartz.scheduler.batchTriggerAcquisitionMaxCount = 60

, however, for some reason, apparently it doesn't take effect. because when I start my application, the log shows that it still uses 1 thread in the pool:

[main] INFO org.quartz.impl.StdSchedulerFactory - Using default implementation for ThreadExecutor 
[main] INFO org.quartz.core.SchedulerSignalerImpl - Initialized Scheduler Signaller of type: class org.quartz.core.SchedulerSignalerImpl 
[main] INFO org.quartz.core.QuartzScheduler - Quartz Scheduler v.2.1.1 created. 
[main] INFO org.quartz.simpl.RAMJobStore - RAMJobStore initialized.
[main] INFO org.quartz.core.QuartzScheduler - Scheduler meta-data: Quartz Scheduler (v2.1.1) 'QuartzScheduler' with instanceId 'NON_CLUSTERED' Scheduler class: 'org.quartz.core.QuartzScheduler' - running locally. NOT STARTED. Currently in standby mode. Number of jobs executed: 0   
Using **thread pool 'org.quartz.simpl.SimpleThreadPool' - with 1 threads.**

I know, the quartz.properties needs to be at class path to be found. and I just did it. any other reason why this file is not detected? or it is detected but number of threads is not set correctly?

Thanks

For those who are using Spring + Quartz and quartz.properties file is not working (i.e. gets ignored while starting the application):

Quartz Scheduler (org.quartz.Scheduler) instantiated by Spring Factory Bean (org.springframework.scheduling.quartz.SchedulerFactoryBean) won't read quartz.properties file from the classpath by default as it's said in Quartz docs - you need to set the reference manually:

[in case of Java config]:

@Bean
public SchedulerFactoryBean schedulerFactoryBean() {
    SchedulerFactoryBean schedulerFactoryBean = new SchedulerFactoryBean();
    schedulerFactoryBean.setConfigLocation(new ClassPathResource("quartz.properties"));
    // ...
}

[in case of XML config]:

<bean class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
    <property name="configLocation" value="classpath:quartz.properties" />
    // ...
</bean>
