quartz + spring, how to cleanup for all jobs from scheduler on startup

[Rossiell]

Hi !
I use quartz-1.6.6 and spring-2.0.2

Could you advise any way to clear up all jobs from scheduler on startup?
The reason for this action: quartz scheduler doesn't remove job from database, if it doesn't use more.
Scheduler only can to overwrite existing jobs.
My configuration:
spring configuration
<bean id="com.companyName.schedulerBean"
class="org.springframework.scheduling.quartz.Sched ulerFactoryBean"
p:waitForJobsToCompleteOnShutdown="true"
p:overwriteExistingJobs="true">
<property name="triggers">
<bean
class="com.expedia.e3.lty.batchprocess.batchservic e.impl.TriggersFactoryBean" />
</property>
<property name="quartzProperties">
<props>
...
<props>

Here my quartz properties:
