1. Re: Scheduler - ClassNotFoundException
casadelnorte Jul 23, 2004 6:09 PM (in response to rkarn)Heard anything about this? I have exactly the same problem. We just upgraded to JBoss 3.2.5 and still experience the same behavior.
Oddly, once we manually save the scheduler-service.xml file in the deploy directory after the server has started up, it works fine. -
2. Re: Scheduler - ClassNotFoundException
netanelw Aug 1, 2004 3:38 AM (in response to rkarn)Hi!
Have solve the problem? from some reason the deploy of the jar is later then the deploy of scheduler-service.xml file and then the jboss cannot find the jar file on on hot redeploy of the xml file....
anything new? -
3. Re: Scheduler - ClassNotFoundException
starksm64 Aug 2, 2004 12:53 AM (in response to rkarn)The depends tag does not delay service creation. It only controls when the service life cycle events are dispatched. You cannot use depends to pick up classes from other deployments. The service definition should be placed into the ejb jar or enclosing ear rather than using the deploy/scheduler-service.xml.

4. Re: Scheduler - ClassNotFoundException
casadelnorte Aug 11, 2004 12:55 PM (in response to rkarn)OK - I'm confused. I have the same problem - my scheduled job I've created in my application won't start until the application is deployed. I get an error on initial load with [Scheduler] Failed to find: com.mycompany.MyScheduledJob.
My question is - how do you get this to work - or what's the "best practices" alternative? Does this have to be created in a jar and placed in the lib directory (which seems weird)?
Once the application has been loaded, I can update (resave) the scheduler-service.xml and things work just fine.
Thanks for any pointers you can provide.
Larry
My scheduler-service.xml contains:<mbean code="org.jboss.varia.scheduler.Scheduler" name=":service=MyScheduledJob"> <attribute name="StartAtStartup">true</attribute> <attribute name="SchedulableClass">com.mycompany.MyScheduledJob</attribute> <attribute name="SchedulableArguments">test,123</attribute> <attribute name="SchedulableArgumentTypes">int,int,java.lang.String</attribute> <attribute name="InitialStartDate">NOW</attribute> <attribute name="SchedulePeriod">1000</attribute> <attribute name="InitialRepetitions">1</attribute> </mbean>

5. Re: Scheduler - ClassNotFoundException
starksm64 Aug 11, 2004 1:19 PM (in response to rkarn)Throw away the schedule-manager-service.xml and scheduler-service.xml files from deploy, and create your own sar that contains a META-INF/jboss-service.xml containing the Scheduler definition. You put your classes in the sar so that you have a self contained deployment. The sar can be a standard java archive or a directory structure.
