JBoss Cache Ticket Registry

JBoss integration is enabled by including the following dependency in the Maven WAR overlay:

<dependency>
     <groupId>org.jasig.cas</groupId>
     <artifactId>cas-server-integration-jboss</artifactId>
     <version>${cas.version}</version>
</dependency>

JBossCacheTicketRegistry stores data in a JBoss Cache that supports distributed caches for failover support and is therefore suitable for HA deployments. Almost all of the configuration for this component happens in the JBoss Cache configuration file; we present a starting configuration here but readers should consult JBoss Cache configuration documentation for further details.

Sample JBossCacheTicketRegistry configuration for ticketRegistry.xml.

<bean id="ticketRegistry"
      class="org.jasig.cas.ticket.registry.JBossCacheTicketRegistry"
      p:cache-ref="cache" />
<bean id="cache"
      class="org.jasig.cas.util.JBossCacheFactoryBean"
      p:configLocation="classpath:jbossCache.xml" />
  </bean>

The jbossCache.xml file may be bundled in the overlay which allows it to be accessed from the classpath, as in the example above, or it may be located on the filesystem. A sample jbossCache.xml file follows.
