Unable to Cluster Quartz with JDBC store in Mule 2.2.1

Hi All,

I am running Mule 2.2.1 and trying to implement the clustered JDBC store for quartz.

When mule starts up and trys to create my quartz jobs I get the following exception:

After reading the exception it would lead me to believe that the DefaultMuleContext is the problem since it is not implementing serializable.  I am hoping to disprove this as I don't want to have to modify Mule code to cluster quartz, nor should I have to.  I have a hard time believing that more people have not tried to cluster quartz in Mule.


Here is my quartz connector configuration:

[code]

    <quartz:connector name="zcorumQuartzConnector">
        <quartz:factory-property key="org.quartz.scheduler.instanceName" value="MyClusteredScheduler"/>
        <quartz:factory-property key="org.quartz.scheduler.instanceId" value="AUTO"/>

        <quartz:factory-property key="org.quartz.threadPool.threadCount" value="15"/>
        <quartz:factory-property key="org.quartz.threadPool.threadPriority" value="5"/>

        <quartz:factory-property key="org.quartz.jobStore.misfireThreshold" value="60000"/>

        <quartz:factory-property key="org.quartz.jobStore.clusterCheckinInterval" value="20000"/>

        <quartz:factory-property key="org.quartz.dataSource.myDS.driver" value="${db.driver}"/>
        <quartz:factory-property key="org.quartz.dataSource.myDS.URL" value="${jdbc.url}"/>
        <quartz:factory-property key="org.quartz.dataSource.myDS.user" value="${db.username}"/>
        <quartz:factory-property key="org.quartz.dataSource.myDS.password" value="${db.password}"/>
        <quartz:factory-property key="org.quartz.dataSource.myDS.maxConnections" value="5"/>
        <quartz:factory-property key="org.quartz.dataSource.myDS.validationQuery" value="select 0 from dual"/>
    </quartz:connector>

Any help would be greatly appreciated.  Thanks,
