Scheduler Using Spring

[Adeel Ansari]

Hey its not working. No errors though, but showing up nothing. The code goes like this...

applicationContext.xml : Snippet

    <!-- Add scheduling bean and trigger configuration here-->
    <bean id="checkSendSmsJob" class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
        <property name="targetObject" ref="smsAutoResponder" />
        <property name="targetMethod" value="checkSendSmsTask" />
    </bean>
    <bean id="smsAutoResponderTrigger" class="org.springframework.scheduling.quartz.SimpleTriggerBean" >
        <property name="jobDetail" ref="checkSendSmsJob" />
        <property name="startDelay" value="0" />
        <property name="repeatInterval" value="10" />
    </bean>

dispatcher.xml : Snippet

    <context:component-scan base-package="com.myblubermax.component.service"/>

SmsAutoResponder.java

@Service
public class SmsAutoResponder {
 
    private final static int STATUS = 0;
 
    public SmsAutoResponder() {
        System.out.println("Initialized....");
    }
 
    @Autowired
    private SmsRequestDao smsRequestDao;
 
    public void setSmsRequestDao(SmsRequestDao smsRequestDao) {
        this.smsRequestDao = smsRequestDao;
    }
    
    
    public void checkSendSmsTask() {
        System.out.println("Started running....");
        List<SmsRequest> smsRequestList = smsRequestDao.selectByStatus(STATUS);
        for(SmsRequest smsRequest : smsRequestList){
            System.out.println(smsRequest);
        }
        
    }
}

Main.java

public class Main {
 
    ApplicationContext ctx = new ClassPathXmlApplicationContext(new String[]{
                "conf/applicationContext.xml", "conf/dispatcher.xml"
            });
    
    public static void main(String[] args) {        
        Main main = new Main();
        try {
            Thread.sleep(90000);
        } catch (InterruptedException ex) {
            Logger.getLogger(Main.class.getName()).log(Level.SEVERE, null, ex);
        }
    }
}

I am getting the message from SmsAutoResponder constructor. But after that for 90 seconds nothing appears and program exits.

Can you spot possible errors or what I am missing?

Thanks.

Does your Spring applicationContext.xml also contain a bean definition for org.springframework.scheduling.quartz.SchedulerFactoryBean specifying the smsAutoResponderTrigger you're using? This is the main Quartz bean that handles firing triggers, calling jobs, etc. If this isn't defined, the trigger isn't going to be fired.

Oops. I missed that. I found it here as well,
Spring Framework Reference : Scheduling. Previously, i failed to notice this particular snippet, I wonder.

Thanks, Nathan.

At first I was following the example given in JavaRanch Journal. It was just fine. The only thing I realized now is, Christophe, repeated the SimpleTriggerBean in that particular example, but not the SchedulerFactoryBean. And I completely agree, that its reasonable to not repeat that since that would be exactly same even if repeated. But I beleive, it would have been better to mention it, at least.

Bottom line, I didn't read that thoroughly and missed that important snippet.
