Question

I am following this link:
http://www.mkyong.com/spring/spring-quartz-scheduler-example/

Everything is working fine. The tutorial shows 3 classes and pom file.

I want to make it work with 2 classes.

However I am having issues.

import org.springframework.context.support.ClassPathXmlApplicationContext;

public class Loader
{
    public static void main( String[] args ) throws Exception
    {
        new ClassPathXmlApplicationContext("Spring-Quartz.xml");
    }
}

This is the second class

public class Runner extends QuartzJobBean
{
    Runner rRun = new Runner();
    public void printMe() {
        System.out.println(" Quartz Running! ~");
    }

    protected void executeInternal(JobExecutionContext context) 
        throws JobExecutionException
    {
        rRun.printMe();
    }
}

This is the pom bean config file:

<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
       http://www.springframework.org/schema/beans/spring-beans-2.5.xsd">


   <bean name="loader"
    class="org.springframework.scheduling.quartz.JobDetailBean">

        <property name="jobClass" value="Loader" />

        <property name="jobDataAsMap">
            <map>
                <entry key="rRun" value-ref="rRun" />
            </map>
        </property>

    </bean>

    <!--
    <bean id="loader" 
      class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">

        <property name="targetObject" ref="rRun" />
        <property name="targetMethod" value="printMe" />

    </bean>
    -->


<bean id="myPropertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
  <property name="location" value="application.properties"/>
  <property name="placeholderPrefix" value="${props:"/>
</bean>

    <!-- Simple Trigger -->
    <bean id="simpleTrigger"
        class="org.springframework.scheduling.quartz.SimpleTriggerBean">

        <property name="jobDetail" ref="loader" />
        <property name="repeatInterval" value="${props:repeatInterval}" />
        <property name="startDelay" value="${props:startDelay}" />

    </bean>

    <!-- Cron Trigger -->
    <bean id="cronTrigger"
        class="org.springframework.scheduling.quartz.CronTriggerBean">

        <property name="jobDetail" ref="runner" />
        <property name="cronExpression" value="${props:cronExpression}" />

    </bean>

    <bean class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
        <property name="jobDetails">
            <list>
            <ref bean="runner" />
            </list>
        </property>

        <property name="triggers">
            <list>
            <ref bean="simpleTrigger" />
            </list>
        </property>

    </bean>

</beans>

Where did I go wrong?

EDIT:

My issues are:

Answer 1

The exception is in regard to your loader bean. It cannot be found in your bean factory or application context:

<bean name="loader"
    class="org.springframework.scheduling.quartz.JobDetailBean">

    <property name="jobClass" value="Loader" />

    <property name="jobDataAsMap">
        <map>
            <entry key="rRun" value-ref="rRun" />
        </map>
    </property>

</bean>

The jobDataAsMap property has an entry that is attempting to reference another bean named rRun, which doesn’t exist in your bean configuration. You probably mean to be adding your class Runner into your bean configuration, like so:

<bean id="rRun" class="package.of.your.class.Runner" />

This will allow the loader bean to find your class in its application context.
