Good nigth!
I'm using the Quartz in the application with Spring.
When the quartz execute the task, is being executed the same task 3 times one after another.
I need someone to help me to configure it is done only once this task.
The configuration I'm using is:

Java Code:
<!-- Level Update Scheduling -->
    <bean id="schedulingLevelService" class="br.com.smartsw.copasbrazil.site.model.service.impl.SchedulingLevelServiceImpl">
    	<constructor-arg ref="userPointService" />
	</bean>	
	<bean id="jobDetailLevelService" class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
		<property name="targetObject" ref="schedulingLevelService"/>
		<property name="targetMethod" value="executeJob"/>
	</bean>	
	<bean id="cronTriggerLevelService" class="org.springframework.scheduling.quartz.CronTriggerBean">
		<property name="jobDetail" ref="jobDetailLevelService" />
		<!-- Configured to run the 00:10hs every day -->
		<!--property name="cronExpression" value="0 10 0 * * ?" /-->
		<property name="cronExpression" value="0 30 14 * * ?" />
	</bean>

	<!-- Scheduling Triggers -->
	<bean class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
		<property name="triggers">
			<list>
				<ref bean="cronTriggerLevelService" />
				
			</list>
		</property>
		<property name="quartzProperties">
                        <props>
                        	 	<prop key="org.quartz.scheduler.instanceName">Scheduler</prop>
                                <prop key="org.quartz.scheduler.instanceId">AUTO</prop> 
                                <!-- Configure ThreadPool -->
                                <prop key="org.quartz.threadPool.class">org.quartz.simpl.SimpleThreadPool</prop>
                                <prop key="org.quartz.threadPool.threadCount">1</prop>
                                <prop key="org.quartz.threadPool.threadPriority">1</prop>
                                <prop key="org.quartz.jobStore.class">org.quartz.simpl.RAMJobStore</prop>
                        </props>
          </property>
	</bean>
I looked in the debug and appeared 3 threads.
I tried to use this "THREADCOUNT" in the hope that it runs only once, but did not work.
Now appreciate the help of someone who can.
Excuse my English, Thanks
