[JMX] - Cannot persist xmbean
by tosca
Hello!
I used the persistent-service.sar example, made it into a non service jar and deployed it.
I'm able to access the bean from the jmx console, get and set properties, but it is never persisted. Why would that be?
the only changes I made are:
Put this at the beginning of the class
@Service (objectName="jboss.jmx:service=PersistentServiceExample", xmbean="resource:ps-xmbean.xml")
Created ps-xmbean.xml, modified it to confirm to xmbean schema.
Only persistence doesn't work. Any pointer on how to debug would be greatly appreciated.
modified jboss-service.xml (ps-xmbean.xml)

| <!-- Inline xmbean descriptor
|
| This is a normal XMBean descriptor, the only different being the
| specification of the DelegatingPersistenceManager as a persistence-manager.
|
| This persistence manager will invoke a factory operations
| (by default apmCreate()) on an external MBean service
| (by default jboss:service=AttributePersistenceService),
| in order to get a reference to an AttributePersistenceManager
| implementation.
|
| The actual AttributePersistenceManager implementation is instantiated
| by the AttributePersistenceService and shared by many
| DelegatingPersistenceManagers. By default an XMLAttributePersistenceManager
| is instantiated, but other implementations are possible.
|
| The external AttributePersistenceService can be use to manage at runtime
| the AttributePersistenceManager implementation, i.e. list persisted ids,
| remove persisted images, or specify a particular 'version-tag' for all
| saved information.
|
| It is important that the external AttributePersistenceService is
| operational when the XMBean that uses it is instantiated. This will
| normally not be a problem since the AttributePersistenceService is most
| probably started by conf/jboss-service.xml
