It doesn't work because of ClassLoader Problems : 11:02:00,022 ERROR [JobStoreTX] Error retrieving job, setting trigger state to ERROR. org.quartz.JobPersistenceException: Couldn't retrieve job because a required class was not found: No ClassLoaders found for: org.jboss.seam.async.QuartzDispatcher$QuartzJob [See nested exception... Is there anybody which success to install quartz with jdbc ? Thx for advance View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4075151#...
