Problem proxying with Quartz MethodInvokingJobDetailFactoryBean

[hguidetti]

Hi all,
I'm using Spring 2.5.1, Quartz 1.5.2 on JDK 1.4.2

I have a problem using the org.springframework.scheduling.quartz.MethodInvoki ngJobDetailFactoryBean.

As I understand the problem comes from an AOP problem.

Here is my configuration :

  <bean id="cacheManager" class="xx.yy.TraderCacheManagerImpl">

  <bean id="ehcacheJob" class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
    <property name="targetObject" ref="cacheManager" />
    <property name="targetMethod" value="flush" />
    <property name="concurrent" value="false" />
  </bean>

  <bean id="ehcacheTrigger" class="org.springframework.scheduling.quartz.SimpleTriggerBean">
    <property name="jobDetail" ref="ehcacheJob" />
    <property name="startDelay" value="5000" />
    <property name="repeatInterval" value="5000" />
  </bean>

The error I get when I load Spring context is java.lang.IllegalArgumentException: Cannot convert value of type [$Proxy29] to required type [org.quartz.JobDetail] for property 'jobDetail': no matching editors or conversion strategy found

org.springframework.beans.PropertyBatchUpdateException; nested PropertyAccessExceptions (1) are:
PropertyAccessException 1: org.springframework.beans.TypeMismatchException: Failed to convert property value of type [$Proxy29] to required type [org.quartz.JobDetail] for property 'jobDetail'; nested exception is java.lang.IllegalArgumentException: Cannot convert value of type [$Proxy29] to required type [org.quartz.JobDetail] for property 'jobDetail': no matching editors or conversion strategy found
	at org.springframework.beans.AbstractPropertyAccessor.setPropertyValues(AbstractPropertyAccessor.java:104)
	at org.springframework.beans.AbstractPropertyAccessor.setPropertyValues(AbstractPropertyAccessor.java:59)
	at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.applyPropertyValues(AbstractAutowireCapableBeanFactory.java:1198)

I have followed the documentation. I don't see any errors.
I probably do something wrong.
Do you have any advice to revolve my problem ?

Thanks a lot for you help.

Hi all,

I have found my problem.

I'm use <aop:config> in my Spring context. So Spring was creating a proxy automatically for all beans.
I don't know why but the SimpleTriggerBean doesn't support injecting a proxy instead of the object itself.

Any idea ?

Ok, I found the solution.
I have added <aop:scoped-proxy proxy-target-class="true" /> in the bean MethodInvokingJobDetailFactoryBean.

  <bean id="ehcacheJob" class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
    <property name="targetObject" ref="cacheManager" />
    <property name="targetMethod" value="flush" />
    <property name="concurrent" value="false" />
    <aop:scoped-proxy proxy-target-class="true" />
  </bean>

Hope this will help others !
