I run a Spring Framework/SmartGWT based web-app, with now an added Quartz job. The job is supposed to run every day at 2am, and picks winners from a DB table. From my logs I see it runs twice, concurrently it seems, because as you can see, the logs overlap:

Generating winners of yesterday...
Generating winners of yesterday...
winning id's: 15
done, mail queue is filled.

winning id's: 18
done, mail queue is filled.

My applicationContext.xml looks like this:

<!-- initiates and calls the job -->  
<beans:bean id="GenerateWinnersAndFillMailingQueueJobDetail" class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean"> 
  <beans:property name="targetObject" ref="GenerateWinnersAndFillMailingQueueJobExecutor"/>  
  <beans:property name="targetMethod" value="execute"/> 
</beans:bean>  
<!-- here's where we use the Cron like scheduling expression      to define when the bean is run. -->  
<beans:bean id="GenerateWinnersAndFillMailingQueueJob" class="org.springframework.scheduling.quartz.CronTriggerBean"> 
  <beans:property name="jobDetail" ref="GenerateWinnersAndFillMailingQueueJobDetail"/>  
  <!-- run every morning at 2AM -->  
  <beans:property name="cronExpression" value="0 0 2 * * ?"/> 
</beans:bean> 
... another quartz jobs is defined here, omitted for clarity ...
<beans:bean class="org.springframework.scheduling.quartz.SchedulerFactoryBean"> 
  <beans:property name="triggers"> 
    <beans:list> 
      <beans:ref bean="GenerateWinnersAndFillMailingQueueJob"/>  
      <beans:ref bean="SendEmailsFromMailQueueJob"/> 
    </beans:list> 
  </beans:property> 
</beans:bean>

I don’t really see what is wrong here, it is a pretty simple use case. When I test this locally, on the server that comes with GWT development mode, it DOES work. Only when deploying to Tomcat6 on Ubuntu 10.04 LTS, I get this issue.

Any ideas?

** edit: after a hint from the comments, increasing the log level, it seems that Spring is running twice. Restarting the tomcat server shows that two Springs are instantiated, about 4 seconds apart.

2011-08-29 08:49:26,484 {ABSOLUTE}  INFO ContextLoader,main:187 - Root WebApplicationContext: initialization started

Later on, two Spring instances seem to be started:

...
2011-08-29 08:49:31,221 {ABSOLUTE}  INFO ContextLoader,main:187 - Root WebApplicationContext: initialization started

What can be causing this, and what’s to be done?

    I fixed it, not only quartz was running twice, but my app was deployed twice. This was because of the following in the Tomcat docs:

    When using automatic deployment, the docBase defined by an XML Context file should be outside of the appBase directory. If this is not the case, difficulties may be experienced deploying the web application or the application may be deployed twice. The deployIgnore attribute can be used to avoid this situation.

    Finally, note that if you are defining contexts explicitly in server.xml, you should probably turn off automatic application deployment or specify deployIgnore carefully. Otherwise, the web applications will each be deployed twice, and that may cause problems for the applications.

    I followed a tutorial on how to get mod_jk working, and this tutorial contained that flaw.
