Hi Jaroslav,
Could you post your entire ticket registry cleaner definition? I tried
setting up a cleaner job patterned after the default ticket registry
cleaner but I am getting
Error creating bean with name 'ticketRegistryCleaner' defined in
ServletContext resource
[/WEB-INF/spring-configuration/ticketRegistry.xml]: Initialization of
bean failed; nested exception is
org.springframework.beans.factory.BeanInitializationException: Bean
state is invalid: logoutManager - may not be null
exceptions on startup. This is what the ticket cleaner definition looks
like:
<!-- 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="3600000" />
