During JBoss load time, the quartz scheduler is started and starts catching triggers of waiting scheduled jobs (from the database). At the time a job is activated, the class which implements quartz Job cannot be instaciated (in order to run the job) and the following Exception is thrown: 10:34:11,427 WARN [ServiceController] Problem starting service jboss.jca:service=RARDeployment,name='quartz-ra.rar' javax.resource.spi.ResourceAdapterInternalException: org.quartz.SchedulerConfigException: Failure occured during job recovery. [See nested exception: org.quartz.JobPersistenceException: Couldn't recover jobs: Couldn't store trigger: No ClassLoaders found for: com.lamark.utils.BillingRetryJob [See nested exception: org.quartz.JobPersistenceException: Couldn't store trigger: No ClassLoaders found for: com.lamark.utils.BillingRetryJob [See nested exception: java.lang.ClassNotFoundException: No ClassLoaders found for: com.lamark.utils.BillingRetryJob]]] at org.jboss.resource.adapter.quartz.inflow.QuartzResourceAdapter.start(QuartzReso urceAdapter.java:58) at org.jboss.resource.deployment.RARDeployment.startService(RARDeployment.java:109 ) How can I ensure that the Job class I created will be created before quartz is loaded?
