Can MC4J modify MBean's properties?

[charles-xie]

MC4J shows each MBean I exported from normal beans, i.e. Quartz task beans and I see 2 properties: "CronExpression" and "NextFireTime" and their getter/setter.

But it seems that MC4J doesn't make effect after I modify values of the "CronExpression" and "NextFireTime" even I click "Execute" button of these methods.

Here is my spring xml configuration and the MC4J shows:

schedule-config.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd">

	<bean	class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
		<property name="triggers">
			<list>
				<ref bean="poScheduleTask" />
			</list>
		</property>
	</bean>
	<bean id="baseJobDetail" abstract="true">
		<property name="concurrent" value="false" />
	</bean>

	<bean id="poScheduleTask"
		class="org.springframework.scheduling.quartz.CronTriggerBean">
		<property name="jobDetail">
			<bean
				class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean"
				parent="baseJobDetail">
				<property name="targetObject" ref="poService" />
				<property name="targetMethod" value="printDate" />
			</bean>
		</property>
		<property name="cronExpression" value="0/5 * * * * ?" />
	</bean>

</beans>

		</property>
	</bean>

</beans>

I make it more clear:
I change the cronExpresstion from "0/5 * * * * ?" to "0/10 * * * * ?" and the nextFireTime in MC4J, but it seems that the task still run every 5 seconds.
