WoW! Thanks for the quick reply, Scott!
I increased the session-timeout for the CAS webapp precisely for the
same reason (i.e. The user should be able to spend 4 hours on a form
before he hits the submit button). We have a web-based photo
application and the user should be able to spend a lot of time
selecting photos before they upload them (hit the submit button). One
of our user's requested this.
I know that I did not intentionally change how often the cleaner runs.
Here are the values from the
cas/WEB-INF/applicaitonContext.xml file:
<!--Quartz -->
<!-- TICKET REGISTRY CLEANER -->
<bean id="ticketRegistryCleaner"
class="org.jasig.cas.ticket.registry.support.DefaultTicketRegistryCleaner"
p:ticketRegistry-ref="ticketRegistry" />
<bean id="jobDetailTicketRegistryCleaner"
class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean"
p:targetObject-ref="ticketRegistryCleaner" p:targetMethod="clean" />
<bean id="triggerJobDetailTicketRegistryCleaner"
class="org.springframework.scheduling.quartz.SimpleTriggerBean"
p:jobDetail-ref="jobDetailTicketRegistryCleaner"
p:startDelay="20000" p:repeatInterval="5000000" />
<bean id="scheduler" class="org.springframework.scheduling.quartz.Schedu
lerFactoryBean">
<property name="triggers">
<list>
<ref local="triggerJobDetailTicketRegistryCle
aner" />
</list>
</property>
</bean>
I appreciate your help Scott. I am hoping that you can help me figure
out what could be going wrong.
Thank you!
