DOSGI : Stopping bundle don't remove service reference from Remote Service Admin

[Jérôme Lelong <ar...@gmail.com>]

  Hello,

  I'm trying to implement a remote OSGI service. I'm using spring DM to
export service and to import service. Exported service and service consumer
are running in to different Karaf container. There is two container which
export the remote service.
  When i'm start Karaf container exporting the services, Service Reference
is correctly reference in ZooKeeper and then correctly register by the
Remote Service Admin :

Bundle-SymbolicName = vault-service-endpoint-dosgi
Bundle-Version = 0.0.1
endpoint.framework.uuid = a6b6f785-0372-4edc-8998-85b15d73031c
endpoint.id = http://localhost:9002/sts/vault
endpoint.package.version.com.sts.confiance.vault.endpoint.dosgi = 0.0.0
endpoint.service.id = 196
objectClass = com.sts.confiance.vault.endpoint.dosgi.VaultServiceDosgi
org.apache.cxf.ws.address = http://localhost:9002/sts/vault
org.springframework.osgi.bean.name = vaultServiceDosgiBean
service.id = 224
service.imported = true
service.imported.configs = org.apache.cxf.ws
service.intents = SOAP.1_1, HTTP, SOAP


  But, when i'm stopping one container exporting the service, the reference
is correctly removed from ZooKeeper, but reference is not unregister from
the Remote Service Admin and an exception is throw when consumer try to call
the remote service. What i want is automatically switch on the other
container. Next step will be to add a Round Robin mode.
  Could you help me.


  Thanks,
  Jérôme



 ============================ Exporting services

<osgi:service id="vaultServiceDosgi" ref="vaultServiceDosgiBean"
interface="com.sts.confiance.vault.endpoint.dosgi.VaultServiceDosgi">
<osgi:service-properties>
<entry key="service.exported.interfaces" value="*" />
<entry key="org.apache.cxf.ws.address" value="
http://localhost:9002/sts/vault" />
</osgi:service-properties>
</osgi:service>


<bean id="vaultServiceDosgiBean"
class="com.sts.confiance.vault.endpoint.dosgi.impl.VaultServiceDosgiImpl">


============================= Importing services

<osgi:reference id="vaultServiceRef"
interface="com.sts.confiance.vault.endpoint.dosgi.VaultServiceDosgi"/>
 <bean class="com.sts.confiance.test.VaultServiceConsumer"
init-method="start" destroy-method="stop">
<property name="vaultService" ref="vaultServiceRef"/>
</bean>
 ============================= Service consumer

public class VaultServiceConsumer {
private static final Logger logger =
LoggerFactory.getLogger(VaultServiceConsumer.class);
 private VaultServiceDosgi vaultService;
private VaultServiceConsumerThread vaultServiceConsumerThread;
 public void setVaultService(VaultServiceDosgi vaultService) {
this.vaultService = vaultService;
}
 public void start() {
        logger.info("Start the vault service consumer");

        vaultServiceConsumerThread = new
VaultServiceConsumerThread(vaultService);
        vaultServiceConsumerThread.start();  <==== this thread only call
vaultService method every 5 seconds
    }
 public void stop() {
vaultServiceConsumerThread.exit();
}
}
