Re: [JBoss-user] Scheduler

I was not able to get a scheduler .sar to work if I deployed it directly in the EAR. However, it does work if I deploy it inside the *ejb-jar*, which is itself inside the EAR.

My working theory is that there is some subtle difference between the EAR deployer and the JAR deployer (maybe the EAR deployer only deploys modules mentioned in the application.xml or in the classpaths of the modules?). But I have not investigated further.

For now, I am OK with this structure. But I would be interested to understand why it behaves like this :-).

Yep, we have the same problem. Your original post said you
needed your scheduler to access a class in your .ear. If you
need to access a bean, then you can't just put the .sar in the
.ear - We solved this by just sleeping for 60 seconds and then
starting - not ideal, but I couldn't find the MBean for
the bean container to make the depends stuff work. If you get
it working could you post a follow-up to the list?

Thanks for the advice.

We can deploy the scheduler MBean by putting it inside a .sar, but we get a similar problem: the first time the scheduler is invoked it does a findAll on a bean that is not deployed. An error message is printed by the loginterceptor (so I'm not sure we can catch it). The next time the scheduler is invoked it works fine, since by that time everything is deployed.

Any suggestions?

Hi all,

Using the online docs at
http://www.jboss.org/online-manual/HTML/ch11s58.html#scheduler-usage and
JBoss3.0.3 we have created a scheduler mbean. We deploy it via a timer
service.xml file. The scheduler mbean refers to a class
(au.com.xcomp.xvs.server.TimedObjectSchedulable) in our ear.

The scheduler deploys fine provided we manually make sure the ear is
deployed before the service.xml. However, when we try to deploy the
service.xml file and ear file in the one ant task, the scheduler deploys
first and gives the error below. Someone else also reported this problem
a while ago
(http://www.mail-archive.com/jboss-user@lists.sourceforge.net/msg23230.html)
.
Any suggestions???

Cause: Incomplete Deployment listing:
Packages waiting for a deployer:
 <none>
Incompletely deployed packages:
 <none>
MBeans waiting for classes:
 <none>
MBeans waiting for other MBeans:
[ObjectName: jboss:schedule=CheckTimeoutDaemon,service=Scheduler
 state: FAILED
 I Depend On:
 Depends On Me: org.jboss.deployment.DeploymentException: Exception

jboss:schedule=CheckTimeoutDaemon,service=Scheduler; - nested throwable:
(java.security.InvalidParameterException: Given class
au.com.xcomp.xvs.server.TimedObjectSchedulable is not valid or not found)]


Thanks
