Spring-managed Quartz starting multiple threads...

[james minter]

Hi,

I suspect I am doing something really silly here (usually the case).

I have Spring starting up a CronTriggerBean like this:

<bean id="quartzSchedulerFactoryBean" class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
	<property name="triggers">
		<list>
			<ref bean="cronEmailTrigger"/>
		</list>
	</property>
	
	<property name="autoStartup" value="true" />
	<property name="applicationContextSchedulerContextKey" value="applicationContext" />
	<property name="waitForJobsToCompleteOnShutdown" value="true" /> 
</bean>

My cron setup is like this:

email.CronTriggerExpression=0 * * * * ?

(i.e. every minute)

However, when I start up Tomcat, instead of getting one job triggering every minute, I get 3 identical jobs starting up.

This is causing no end of problems as you can imagine. It looks like 3 instances of Quartz are being started up.

Anyone else come across this?

In case it helps, here is my Tomcat server.xml:

<?xml version='1.0' encoding='utf-8'?>

<Server port="8005" shutdown="SHUTDOWN">

  <Listener className="org.apache.catalina.core.AprLifecycleListener" SSLEngine="on" />
  <Listener className="org.apache.catalina.core.JasperListener" />
  <Listener className="org.apache.catalina.mbeans.ServerLifecycleListener" />
  <Listener className="org.apache.catalina.mbeans.GlobalResourcesLifecycleListener" />

  <GlobalNamingResources>
    <Resource name="UserDatabase" auth="Container"
              type="org.apache.catalina.UserDatabase"
              description="User database that can be updated and saved"
              factory="org.apache.catalina.users.MemoryUserDatabaseFactory"
              pathname="conf/tomcat-users.xml" />
  </GlobalNamingResources>

  <Service name="Catalina">
    
    <Connector port="80" protocol="HTTP/1.1" 
               connectionTimeout="20000" 
               redirectPort="8443" />

    <Connector port="8009" protocol="AJP/1.3" redirectPort="8443" />


    <Engine name="Catalina" defaultHost="website.co.uk">

      <Realm className="org.apache.catalina.realm.UserDatabaseRealm"
             resourceName="UserDatabase"/>

      <Host name="website.co.uk" debug="0" appBase="webapps"
             unpackWARs="true" autoDeploy="false"
             xmlValidation="false" xmlNamespaceAware="false">
              
              <Alias>w-w-w.website.co.uk</Alias>       
              
              <Logger className="org.apache.catalina.logger.FileLogger"
                       directory="logs"  prefix="website_log." suffix=".txt"
                  timestamp="true"/>  
                  
      	<Context path="/" docBase="/Website" debug="0" reloadable="true"/>                  
      </Host>
    
      <Host name="websitefe.co.uk" debug="0" appBase="webapps"
             unpackWARs="true" autoDeploy="false"
             xmlValidation="false" xmlNamespaceAware="false">
              
              <Alias>w-w-w.websitefe.co.uk</Alias>       
              
              <Logger className="org.apache.catalina.logger.FileLogger"
                       directory="logs"  prefix="websitefe_log." suffix=".txt"
                  timestamp="true"/>  
                  
      	<Context path="/" docBase="/WebsiteFE" debug="0" reloadable="true"/>  
      	
	<Resource name="jdbc/website" auth="Container" type="javax.sql.DataSource"
		       maxActive="100" maxIdle="30" maxWait="10000"
		       username="website" password="website" driverClassName="com.mysql.jdbc.Driver"
		       url="jdbc:mysql://localhost:3306/website?autoReconnect=true"/>      	
      </Host>  
      
    </Engine>
  </Service>
</Server>

(the w-w-w bit is just because this forum won't let me put URLs in).

Many thanks for any suggestions,

James.

Hi,

Well, I've found a solution (or at least a work-around). I've found that putting:

deployOnStartup="false"

in the <Host> tag in server.xml seems to fix the problem.
