Hi, i have a little problem with quartz (v 1.5.2) and JDBCJobStore, problem is simple:

I'm creating quartz Job POJO Class with simple task what printing on console "Hello" string, it looks like this:

Code:
public class SimpleQuartzTest extends QuartzJobBean {

	@Override
	protected void executeInternal(final JobExecutionContext context) throws JobExecutionException {
		System.out.println("Hello");

	}

}
next, I'm adding into spring context xml bean, what is creating quartz tables in my database, if don't exist.
Code:
<bean id="quartzDbInitializer" class="org.springframework.jdbc.datasource.init.DataSourceInitializer">
	<property name="dataSource" ref="dataSource" />
	<property name="enabled" value="true" />
	<property name="databasePopulator">
		<bean class="org.springframework.jdbc.datasource.init.ResourceDatabasePopulator">
                     ....
                </bean>
        </property>
</bean>
and bean for creating scheduler, what use database tables created from code abow:

Code:
	<bean id="nextScheduler" class="org.springframework.scheduling.quartz.SchedulerFactoryBean"
		depends-on="quartzDbInitializer">

		<property name="triggers">
			<list>
				<ref bean="cronTrigger" />
			</list>
		</property>
		<property name="dataSource">
			<ref bean="dataSource" />
		</property>
		<property name="transactionManager">
			<ref bean="transactionManager" />
		</property>
		<property name="quartzProperties">
			<props>
				<prop key="org.quartz.jobStore.tablePrefix">
				QRTZ_
				</prop>
				<prop key="org.quartz.jobStore.selectWithLockSQL">
				SELECT * FROM {0}LOCKS UPDLOCK WHERE LOCK_NAME = ?
				</prop>
			</props>
		</property>
	</bean>
when I have database and scheduler ready, i'm creating jobDetail bean and trigger (running every 1 second) for SimpleQuartzTest Job represented by SimpleQuartzTest.class:

Code:
	<bean name="simpleQuartzTest" class="org.springframework.scheduling.quartz.JobDetailBean">
		<property name="jobClass" value="pl.com.stream.next.asen.server.scheduling.SimpleQuartzTest" />
	</bean>

	<bean id="cronTrigger" class="org.springframework.scheduling.quartz.CronTriggerBean">
		<property name="jobDetail" ref="simpleQuartzTest" />
		<property name="cronExpression" value="* * * * * ?" />
	</bean>
ok i have everything i want, I can run my application now.
When i run my application, everything works fine, and 'Hello' is printing on screen. App works fine. so i close it.

But, i think, that i don't need SimpleQuartzTest Job any more, so I want delete it. I remove SimpleQuartzTest.java file from workspace, JobDetailBean and CronTriggerBean from context xml file, I remove trigger from 'nextScheduler' bean to.

When i run my application again, quartz want's to restore simpleQuartzTest from database, of course there is no more class name SimpleQuartzTest in project, so quartz gets ClassNotFoundException. As a result quartz don't start.

In attachment is full exception I get (txt compressed by zip).Attachment 4390

What can I do with this ? maybe there is some property in quartz or spring what can i set and eliminate this problem.

Thanks for all answers.
