有人遇到过这种奇怪的问题吗？关于Spring集成quartz并持久化方面的问题。

spring配置文件中的配置如下（截取片段）：

<bean id="Scheduler" lazy-init="false" autowire="no"
    class="org.springframework.scheduling.quartz.SchedulerFactoryBean" >
</bean>





<bean id="addJob" class="com.dhcc.scheduler.action.AddAction">
<property name="scheduler">
<ref local="Scheduler"/>
</property>
</bean>

AddAction的定义如下：

package com.dhcc.scheduler.action;

import org.springframework.scheduling.quartz.CronTriggerBean;
import org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean;
import org.springframework.scheduling.quartz.SchedulerFactoryBean;

import com.opensymphony.xwork2.ActionSupport;

public class AddAction extends ActionSupport {
// 添加新任务的操作对象
private SchedulerFactoryBean scheduler;
private MethodInvokingJobDetailFactoryBean jobdetail;
private CronTriggerBean cron;

@Override
public String execute() throws Exception {
    return super.execute();
}

public SchedulerFactoryBean getScheduler() {
    return scheduler;
}

public void setScheduler(SchedulerFactoryBean scheduler) {
    this.scheduler = scheduler;
}

public MethodInvokingJobDetailFactoryBean getJobdetail() {
    return jobdetail;
}

public void setJobdetail(MethodInvokingJobDetailFactoryBean jobdetail) {
    this.jobdetail = jobdetail;
}

public CronTriggerBean getCron() {
    return cron;
}

public void setCron(CronTriggerBean cron) {
    this.cron = cron;
}

}

但是部署到tomcat却保这样一个错误：（如此奇怪的错误。。。）

然而我根本没有使用org.quartz.impl.StdScheduler这个类，为什么会报类型错误呢》》》？？哪位大哥见多识广的，解救一下。
[b]问题补充：[/b]
谢谢各位大哥们的回答，，问题解决方式我知道，我想搞清楚的是，spring配置文件加载时，里面的bean是怎么加载的，具体发生了什么，是容器自动调用了其构造方法呢，还是init方法，抑或是其他。。。这个方面了解的还不深入，还望哪位大哥指点。。。正如我上面程序一样，为什么工厂类加载后，将其注入给其他对象时，类型就变了呢》》》？？？

    你没搞明白这个bean
    class="org.springframework.scheduling.quartz.Scheduler[color=red]FactoryBean[/color]" >

    它是一个工厂bean，得到的不是它本身，而是它负责创建的org.quartz.impl.StdScheduler对象

    这里要修改下
    public class AddAction extends ActionSupport {
    // 添加新任务的操作对象
    private StdScheduler scheduler;
    private MethodInvokingJobDetailFactoryBean jobdetail;
    private CronTriggerBean cron;
